However, with the right guidance, you’ll soon be able to set up an account, choose a provider, and ensure your new email is secure. This section will walk you through the basic steps of creating an email account, help you compare popular email providers, and guide you on setting up security measures to protect your information.

Prepare the System and Choose the Right Email Provider

Before diving into how to create an email account, it’s important to choose the right email provider. There are a number of factors to consider, such as security, privacy policies, and integration with other services.

Popular email providers like Gmail, Yahoo, and Outlook offer different features that may appeal to various users. For instance, Gmail is known for its integration with Google’s suite of services, while Yahoo offers generous storage limits. Outlook stands out for its clean interface and strong connection with Microsoft tools.

When deciding on an email provider, take note of the following:

• Security Features: Look for options like two-factor authentication (2FA) to help protect your account.
• Privacy Policies: Understand how your provider handles your data and what information they collect.
• Storage Space: Consider how much storage space you need, especially if you plan to store a lot of emails and attachments.

Create Your Email Account: A Simple Walkthrough

Once you’ve chosen an email provider, the next step is to create your email account. Here’s a simple, step-by-step walkthrough of how to create an email account:

1. Go to the Provider’s Sign-Up Page

   Navigate to the sign-up page of your chosen provider. For example, if you’re using Gmail, go to the Gmail sign-up page.

2. Enter Your Details

   Fill out your personal information, such as your name, preferred email address, and password. Make sure to choose a strong password that is at least 8 characters long and includes a mix of letters, numbers, and symbols.

3. Set Up Recovery Options

   Many providers will ask for a recovery email or phone number in case you forget your password. It’s important to provide these to ensure you can recover your account if needed.

4. Agree to Terms and Conditions

   Read through the provider’s terms and conditions, then agree to them to proceed with creating your account.

These steps should help you quickly set up a basic email account, whether you’re using Gmail, Yahoo, or Outlook.

Verify Your Account and Set Initial Preferences

After you’ve created your email account, the next step is verification. Providers typically require you to verify your account by confirming your email address or phone number. Here’s how to do it:

1. Email Verification

   For most providers, you will receive a verification email. Click the link inside the email to confirm your address and activate your account.

2. Phone Number Verification

   Some providers, like Gmail, may also ask for a phone number. This is used to help secure your account and recover it if necessary.

3. Set Initial Preferences

   Once your account is verified, it’s a good idea to set up some basic preferences:

   • Password Settings: Choose a strong password, and enable two-factor authentication (2FA) for added security.
   • Privacy Settings: Review your privacy settings to control who can send you emails or see your account information.
   • Recovery Options: Ensure your recovery email and phone number are correctly set up in case you need to recover your account in the future.

By following these simple steps, your email account will be ready to use and secure. You can now start sending and receiving emails while keeping your information safe.

Step-by-Step Guide: How to Set Up Your Email Account

Creating an email account is a simple process that opens the door to endless communication possibilities. Whether you’re setting it up for personal use, business, or both, understanding how to create an email account, compare services, and configure it with essential security features is crucial for a smooth experience. This guide walks you through the steps to set up your email account and optimize it for security and usability.

Overview of Popular Email Providers and Their Key Features

When learning how to create an email account, it’s important to understand which providers offer the best features for your needs. Some of the most popular email services include Gmail, Outlook, and Yahoo, each offering unique benefits:

• Gmail: Known for its simple interface and strong integration with Google services like Google Drive and Google Calendar. It provides 15 GB of free storage and robust spam filtering.
• Outlook: A solid choice for both personal and business email, Outlook offers seamless integration with Microsoft Office tools. It includes 15 GB of free storage and an excellent user interface.
• Yahoo Mail: Offers 1 TB of free storage, making it a good choice for users who need a lot of space. It also provides enhanced spam filters and a user-friendly interface.

Each provider has its strengths, so choose one based on your preferences for storage, integration with other tools, and ease of use.

How to Evaluate Privacy Policies and Security Features

When setting up an email account, privacy and security are key considerations. To evaluate the privacy and security features of different providers:

1. Read the Privacy Policy: Before creating your account, take a few minutes to review the email provider’s privacy policy. Pay attention to how your data is collected and used, whether the provider shares your information with third parties, and your rights as a user.
2. Check for Encryption: Look for information about email encryption to ensure your emails are secure. Providers like Gmail and Outlook offer built-in encryption for sending and receiving emails.
3. Two-Factor Authentication (2FA): This adds an extra layer of security by requiring a second form of verification, such as a text message or an app, in addition to your password.

For example, enabling 2FA on Gmail is a simple yet effective way to secure your account. Follow the instructions here to get started.

Comparing Email Storage Limits and Account Types

When deciding how to create an email account, consider the storage limits provided by each email service. Most providers offer both free and premium plans with varying storage capacities:

• Gmail: Provides 15 GB of free storage, shared across Google Drive, Gmail, and Google Photos. You can upgrade to Google One for more storage.
• Outlook: Offers 15 GB of free storage for email, with additional storage available through Microsoft 365 subscriptions.
• Yahoo Mail: Provides 1 TB of free storage, which is great for users who need extensive email storage without upgrading to a premium plan.

For personal use, free plans with sufficient storage should meet most needs. However, if you anticipate sending and receiving large files or storing a lot of emails, you might want to consider upgrading to a premium plan.

Business vs. Personal Use: Choosing the Right Email Provider

Choosing the right email provider depends on whether you need it for personal or business use. Here’s how to decide:

• Personal Use: For casual use, Gmail or Yahoo are excellent options. They offer ease of use, ample storage, and reliable security features. Gmail’s integration with Google services makes it a top choice for many.
• Business Use: If you need an email service for business, you might prefer Outlook or even a dedicated business solution like Zoho Mail. These providers offer features designed for business needs, such as custom domains, advanced security measures, and collaboration tools.

For instance, Gmail works well for personal use, while a business may require additional features like custom email domains and professional support, which providers like Zoho Mail or Microsoft 365 offer.

It has a more limited free storage option compared to Gmail and Outlook, but its security features make it an excellent choice for users concerned about privacy. ProtonMail is fully compliant with Swiss privacy laws.

These providers stand out in terms of both functionality and security, making them strong options for most users.

How to Evaluate Privacy Policies and Security Features

When setting up an email account, it’s crucial to evaluate the privacy policies and security features of your chosen provider. Here’s what to look for:

• Encryption: Look for providers that offer end-to-end encryption, such as ProtonMail, which ensures your emails are secure from unauthorized access.
• Two-Factor Authentication (2FA): Most top email services, like Gmail and Outlook, support 2FA, adding an extra layer of protection to your account.
• Privacy Laws: Consider how well providers comply with privacy regulations. For example, ProtonMail adheres to Swiss privacy laws, offering strong protection for users in countries with strict data privacy rules.

These features are essential to ensure your personal and professional information remains secure, especially if you plan to use email for sensitive communications.

Comparing Email Storage Limits and Account Types

When creating an email account, it’s also important to consider email storage limits and whether the provider offers free vs. paid options:

• Gmail: Provides 15GB of free storage for emails and files across Google services. Paid options are available through Google One, which offers additional storage for a low monthly fee.
• Outlook: Offers 15GB of free storage for emails. Premium plans include 50GB of storage and access to Microsoft 365’s suite of apps.
• ProtonMail: Provides 500MB of free storage with paid plans offering up to 20GB of space.

For most users, free accounts will suffice, but if you anticipate needing more space, it’s worth considering the paid options that provide extra storage and additional features.

Business vs. Personal Use: Choosing the Right Email Provider

Choosing the right email provider depends on your specific needs—whether it’s for personal or business use. Here’s a breakdown:

• Personal Use: Providers like Gmail and Outlook are ideal for personal use due to their large free storage options and user-friendly interfaces. They are suitable for light to moderate email needs and integrate well with other apps like calendars and cloud storage.
• Business Use: For business purposes, email services like Microsoft 365 offer a professional email address, additional storage, and advanced collaboration tools. These tools allow teams to work together efficiently, offering features like shared calendars and access to cloud-based office software.

When setting up an email for personal use, ease of access and free storage are key. For business, prioritize integration with productivity tools and advanced security features.

By evaluating popular email providers, understanding their privacy and security features, and comparing storage limits and account types, you’ll be equipped to make an informed decision when creating an email account. Whether you’re choosing for personal or business use, keep in mind the key aspects of security, storage, and privacy to find the provider that best fits your needs.

How to Secure Your Email Account: Privacy Policies and Security Features

When learning how to create an email account, securing it should be your top priority. Email is a key point of contact for most online activities, including banking, social media, and sensitive communications. With cyber threats on the rise, it’s crucial to understand how to protect your email account and ensure its privacy. This section will walk you through security features, privacy policies, and key considerations when setting up your email account.

The Role of Two-Factor Authentication in Email Security

Two-factor authentication (2FA) is one of the most effective ways to secure your email account. It adds an extra layer of protection by requiring two forms of identification before granting access. First, you enter your password, and then you must confirm your identity with a second factor, such as a code sent to your phone.

Setting up 2FA is straightforward with most email providers. For example, if you use ProtonMail, you can follow these simple steps:

1. Log in to your ProtonMail account.
2. Go to Settings > Security.
3. Enable Two-Factor Authentication and follow the prompts to link your phone number or authentication app.

This process significantly reduces the likelihood of unauthorized access, making it much harder for attackers to hijack your account, even if they manage to obtain your password.

For more on setting up 2FA, check out this guide on ProtonMail’s website.

Choosing Between Free and Paid Email Accounts for Security

When choosing between free and paid email services, security should be a key consideration. While free services like Gmail offer basic protection, paid services generally provide enhanced features like encryption, better spam protection, and additional privacy features.

• Free Email Services: Providers like Gmail offer good security features, such as spam filtering and built-in two-factor authentication, but they often prioritize ads and data mining, which may compromise privacy.
• Paid Email Services: Services like ProtonMail or Tutanota offer end-to-end encryption, stronger privacy policies, and zero-access encryption, meaning even the provider cannot access your data. They also often come with better spam filtering and more robust security tools.

If email security and privacy are your main concerns, investing in a paid service may be worthwhile, especially if you’re dealing with sensitive or confidential information.

What to Look for in Spam Filtering and Email Protection Features

Effective spam filtering and email protection features are vital for maintaining a secure email account. Spam filters help block unwanted emails, reducing the risk of phishing attacks, which often appear as fraudulent emails designed to steal personal information.

When choosing an email provider, look for the following protection features:

• Spam Filters: Good providers like ProtonMail use advanced algorithms to detect and block spam, preventing malicious emails from reaching your inbox.
• Phishing Detection: Many email providers, including Gmail and Outlook, include phishing detection features to warn you about suspicious links or attachments in incoming emails.
• Antivirus Scanning: Some providers offer antivirus scanning for attachments, helping prevent malware infections.

These features help ensure that your email account is protected from the most common types of online threats.

Best Practices for Keeping Your Email Account Secure After Setup

Securing your email account doesn’t end once it’s set up. It’s important to continue practicing good security habits. Here are some best practices:

1. Use a Strong Password: Create a complex password with a mix of letters, numbers, and symbols. Avoid using easily guessable information like birthdays or common words.
2. Enable Two-Factor Authentication (2FA): As discussed earlier, this is one of the most effective ways to secure your account.
3. Be Wary of Phishing Attempts: Never click on suspicious links or open attachments from unknown senders.
4. Regularly Review Account Activity: Keep an eye on your account’s activity and look for any signs of unauthorized access.

By following these simple yet effective practices, you can greatly reduce the risk of a breach.

Caasify: Ensuring Compliance and Security for Email Management

When managing email for businesses or compliance-heavy environments, it’s crucial to use services like Caasify, which ensure adherence to security and privacy regulations. Caasify offers compliance with industry standards such as GDPR, ensuring that your email management practices are secure and aligned with legal requirements. This adds an additional layer of trust, especially for businesses handling sensitive customer data.

In conclusion, securing your email account is essential for protecting your privacy and ensuring that sensitive information remains safe. By using two-factor authentication, choosing the right provider, and following best practices, you can confidently manage your email account’s security and privacy.

Optimizing Your Email Account: Tips for Filters, Integrations, and Security Enhancements

Now that you’ve set up your email account, it’s time to make the most of it by optimizing various features. Whether you’re looking to clean up your inbox, integrate your email with productivity tools, or boost security, there are plenty of options available. In this section, we’ll cover practical tips to improve your email experience, from setting up filters to integrating helpful tools, and enhancing your account’s security.

How to Set Up Email Filters and Organize Your Inbox

One of the easiest ways to stay organized is by using email filters. Filters automatically sort your incoming emails into folders based on certain criteria, helping you avoid a cluttered inbox. For example, you can filter all emails from a specific sender into a designated folder. Here’s how to set up a basic filter:

1. Gmail:
   • Open Gmail and click on the gear icon, then select See All Settings.
   • Go to the Filters and Blocked Addresses tab and click on Create a New Filter.
   • Enter the email address or keyword you want to filter, then click Create Filter.
   • Choose actions like Skip the Inbox (Archive it) or Apply the label to organize the emails into folders.
2. Outlook:
   • Click on the Settings gear icon, then select View all Outlook settings.
   • Navigate to Mail > Rules and click on Add new rule.
   • Define the criteria for your rule (such as sender or subject) and choose an action, like moving the email to a folder.

Filters help you stay organized and reduce distractions by automatically sorting emails as they arrive.

Integrating Your Email with Productivity Tools

Integrating your email with productivity tools like Google Calendar or Microsoft Teams can save time and increase efficiency. Here’s how you can link your email to some common tools:

• Google Calendar: If you use Gmail, linking your email to Google Calendar automatically adds events from your emails (like meeting invitations) to your calendar. To integrate:
  • In Gmail, open an email with a calendar invitation.
  • Click on Add to Calendar to save it to your Google Calendar.
• Microsoft Teams: If you use Outlook, linking it with Teams allows you to schedule and join meetings directly from your inbox. You can do this by adding your Microsoft Teams account under Outlook Settings > Calendar.

These simple integrations streamline your workflow and keep all your important tasks in one place.

Configuring Email Forwarding and Auto-Reply Features

Email forwarding and auto-replies are essential tools for managing communication, especially when you’re away or need to redirect emails to another address.

• Setting Up Email Forwarding:
  • Gmail: Go to Settings > Forwarding and POP/IMAP, then click on Add a forwarding address. Enter the email address where you want your emails forwarded.
  • Outlook: Go to Settings > View all Outlook settings > Mail > Forwarding, and enable forwarding to another email address.
• Auto-Reply Setup: Set up an out-of-office auto-reply to notify senders when you’re unavailable.
  • Gmail: In the Settings menu, click Vacation Responder and set your start and end dates with a message.
  • Outlook: Go to Settings > Automatic Replies, and write your auto-reply message.

These features help you maintain communication while keeping your inbox organized.

Email Account Recovery: Ensuring Access in Case of Issues

Having a recovery plan for your email account is crucial to avoid losing access. Most email providers allow you to add a secondary email or phone number to help recover your account.

• Gmail: To set up account recovery, go to Settings > Accounts and Import and add a recovery email address or phone number.
• Outlook: Go to Settings > Security > Additional Security Options, and add a backup email or phone number.

By setting up these recovery options, you ensure that you can regain access if you forget your password or face other account issues.

Comparing Different Email Providers: Making an Informed Decision

When it comes to how to create an email account, choosing the right email provider is essential for both personal and business use. The variety of available options can be overwhelming, but focusing on key factors such as privacy policies, uptime reliability, and the features offered can make the decision easier. In this section, we will compare popular email providers to help you select the one that best suits your needs.

Choosing the Best Email Provider Based on Privacy Policies

Privacy is a critical consideration when choosing an email provider. Some providers, like Gmail, rely on data collection to support targeted advertising, while others, like ProtonMail, prioritize privacy and security.

• Gmail: Gmail collects user data to serve personalized ads and improve service features. While it offers robust features, its privacy policies might not be ideal for users prioritizing confidentiality.

Evaluating Uptime and Reliability for Business Use

When selecting an email provider for business purposes, uptime reliability is paramount. You want an email service that guarantees consistent access to your account, especially during working hours.

• Gmail: Google offers a high level of uptime reliability, typically exceeding 99.9%. For business users, Google also provides Service Level Agreements (SLAs) for paid plans, ensuring guaranteed uptime.
• Outlook: As a Microsoft product, Outlook also provides excellent uptime, typically above 99.9%. It is highly trusted in the corporate world due to its integration with other Microsoft tools.
• ProtonMail: While ProtonMail is a great choice for privacy, its uptime isn’t as consistent as Gmail or Outlook for business-critical operations, especially on the free plan.

How to Compare Email Features for Personal and Business Needs

When comparing email providers, it’s important to look at the specific features that suit your needs, whether for personal use or business purposes.

• Storage: Gmail offers 15 GB of free storage, which is shared across Google services. Outlook offers similar storage options, while ProtonMail’s free plan is limited to 500 MB of storage, with paid options offering more.
• Collaboration Tools: Gmail excels with Google Workspace tools like Google Docs and Sheets, making it a great choice for those who need collaboration features. Outlook, integrated with Microsoft Office, offers similar business-focused collaboration features.
• Custom Domains and Professional Features: Outlook and Gmail (with G Suite) allow custom email domains, which is crucial for business use. ProtonMail offers this feature as well but at a higher price point.

By evaluating these factors, you will be well-equipped to choose the best email provider for your needs, whether it’s for personal use or business purposes.

Post-Setup Email Optimization and Maintenance

After creating an email account, it’s essential to optimize and maintain it for better usability, security, and seamless integration with other tools. Whether you’re creating an email account for personal or professional use, fine-tuning configurations such as email aliases, security settings, and backup strategies will ensure a smooth and efficient experience.

How to Manage Email Account Aliases and Custom Domains

Email aliases and custom domains can enhance your email management by allowing you to use multiple addresses without needing additional accounts. Here’s how you can set them up:

1. Adding an Email Alias in Outlook:
   • Go to Outlook Alias Management for detailed steps.
   • Navigate to Settings > View all Outlook settings.
   • Under Mail, select Sync email and then Manage aliases.
   • Click Add alias, choose the alias name, and complete the process. This alias will act like a second email address linked to your primary account.

   Why use aliases?
   Aliases are useful for managing different purposes, such as having separate addresses for work, personal use, or newsletters, without creating new accounts.

2. Linking a Custom Domain to Your Gmail Account:
   • Visit Google Domains or your domain provider’s dashboard.
   • Set up MX records to direct emails sent to your custom domain to your Gmail account.
   • Once set up, you can send and receive emails from your custom domain through Gmail. Check Google’s official domain setup guide for further details.

   Custom domains lend professionalism and control over your email identity, particularly useful for businesses or brands.

Troubleshooting Common Email Setup Issues

When setting up an email account, you may encounter issues such as incorrect passwords or syncing failures. Here’s how to address them:

1. Fixing “Incorrect Password” in Gmail:
   • If you can’t log in due to a password issue, try resetting your password by clicking Forgot password? on the login screen.
   • Follow the on-screen instructions, and make sure your new password meets Gmail’s security criteria (e.g., minimum length, character variety).
2. Resolving Sync Issues in Outlook:
   • If Outlook is not syncing emails with your mobile device, check the sync settings.
   • Go to File > Account Settings > Account Settings.
   • Select your account, click Repair, and follow the instructions to fix sync issues.

These simple steps should help resolve most common email setup problems, ensuring a smoother experience after you set up your email account.

Backup Strategies for Important Email Data

Backing up your email data ensures you don’t lose valuable information in case of accidental deletions or system failures. Here are some effective strategies:

1. Backing Up Emails in Gmail:
   • In Gmail, go to Settings > See all settings > Forwarding and POP/IMAP.
   • Enable POP for all mail and download your emails to an external device using an email client like Thunderbird. Alternatively, use Google Takeout to export all your Gmail data.

   Why back up?
   Backups prevent the loss of important correspondence, attachments, or historical data, which could be vital for work or personal reference.

2. Backing Up Emails in Outlook:
   • In Outlook, go to File > Open & Export > Import/Export.
   • Choose Export to a file and select Outlook Data File (.pst).
   • Follow the instructions to export your emails and save them securely.

   For cloud backups, use services like OneDrive or Google Drive to back up your emails automatically and have peace of mind knowing your data is safe. Check out the official guide for backing up Outlook emails for detailed steps.

By implementing these backup strategies, you ensure that your email data is safe and recoverable if needed.

What is an Ad Blocker and How Does It Enhance Your Browsing Experience?

An ad blocker is a tool that helps you avoid seeing unwanted ads while browsing the web. By blocking these ads, ad blockers not only improve your browsing experience but also enhance your online privacy, reduce page load times, and create a cleaner, distraction-free environment. This section will explore the importance of ad blockers, how they improve website performance, and the common features that make them so effective.

Understanding the Importance of Ad Blockers for Online Privacy

Ad blockers play a crucial role in protecting your online privacy. Every time you visit a website, various tracking scripts from advertisers and third-party services collect data about your browsing habits. These trackers can follow you across different websites, building a detailed profile of your activities. This type of data collection, known as web tracking, is often used to target you with personalized ads.

By using an ad blocker, you can prevent these tracking scripts from running, ensuring that your browsing activities remain private. For example, an ad blocker can block cross-site tracking, meaning advertisers can no longer track your movements from one website to another. This not only enhances your privacy but also protects you from the risk of malvertising—ads that contain malware designed to harm your computer.

For more information on the privacy benefits of ad blockers, check out the Ad Blockers & Online Privacy: A Comparative Analysis of Privacy Enhancing Technologies (2024).

How Ad Blockers Improve Website Performance

Another significant benefit of ad blockers is their ability to enhance website performance. Ads, especially pop-up ads and video ads, are often large and resource-heavy, slowing down your browsing experience. An ad blocker can prevent these elements from loading, reducing the overall load time of web pages. As a result, you’ll experience faster page loading, especially on media-heavy sites.

For example, a website with numerous ads may take several seconds to load fully, but when you use an ad blocker, many of those ads are blocked before they can even begin to load. This improvement in speed not only makes your browsing experience smoother but can also help reduce data usage, which is especially beneficial for mobile users or those with limited bandwidth.

To learn more about how ad blockers can reduce bandwidth usage and speed up page loads, visit the benefits of ad blocking — reduced bandwidth use and faster page loads.

Common Ad Blocker Features and What They Do

Ad blockers come with various features that work together to improve your browsing experience. Here are some of the most common features and how they benefit you:

• Pop-up and Overlay Blocking: Many websites use pop-up ads or overlays that can disrupt your browsing experience. Ad blockers stop these intrusive elements from appearing, creating a more seamless and uninterrupted experience.
• Ad Removal: One of the primary functions of an ad blocker is to remove display ads from websites. This ensures that you only see the content you want to engage with, not distracting banners or video ads.
• Tracking Prevention: Modern ad blockers are also designed to prevent trackers from monitoring your activity across websites. This helps to maintain your online privacy and reduces the amount of personal data shared with advertisers.
• Custom Block Lists: Some ad blockers, like uBlock Origin, allow you to create custom block lists, giving you full control over the types of ads and trackers you want to block. This level of customization ensures that your ad-blocking tool fits your specific needs.

Each of these features contributes to a better browsing experience, focusing on improving website speed, maintaining privacy, and blocking unwanted distractions.

How Ad Blockers Work: Understanding Their Core Functionality

Ad blockers are software tools designed to prevent ads from being displayed on websites. By using different technologies and filter lists, they offer users a cleaner, faster, and more private browsing experience. Understanding how ad blockers work is crucial for anyone looking to improve their online safety or browsing efficiency. For a more in-depth look at how these tools work, check out this HubSpot guide on how ad blocking works.

Ad Blocker Technologies: Browser Extensions vs. Network-Level Blockers

Ad blockers can be divided into two main categories: browser extensions and network-level blockers. Both types aim to block unwanted ads, but they do so in different ways.

• Browser Extensions: These are tools installed directly into your web browser (such as Chrome, Firefox, or Safari). Popular examples include uBlock Origin and AdBlock Plus. Browser extensions work by analyzing the content on a webpage as it loads, identifying and blocking ads based on pre-configured filter lists. They operate locally on your device, meaning that only the browser you’re using will have ads blocked.
• Network-Level Blockers: These are more comprehensive tools that operate at the network level, often across multiple devices. Pi-hole is a well-known example. Network-level blockers filter ads and other unwanted content before it even reaches your device, often by using DNS filtering. This means that no matter what browser or device you’re using, ads are blocked at the network level.

Each type has its own benefits and limitations. Browser extensions are simple to install and configure, but they only affect the browser they’re installed in. Network-level blockers, on the other hand, can block ads across all devices connected to your network, but they may require more technical setup.

For more details on how browser extensions work, visit uBlock Origin’s Wiki.

The Role of Filters in Blocking Ads

Filters are the backbone of how ad blockers function. These filter lists consist of rules that tell the ad blocker what to look for and block. For example, filter lists like EasyList identify common ad patterns—such as banners, pop-ups, and video ads—and instruct the ad blocker to block them when encountered.

There are two main types of filters:

1. URL-based filters: These target specific URLs that are known to serve ads.
2. Element-based filters: These focus on blocking the elements on a webpage (e.g., banners or scripts) that are used to display ads.

When you load a webpage, the ad blocker checks each element against its filter lists. If the element matches an ad pattern, it’s blocked. This system is simple yet effective for preventing many types of intrusive ads.

For instance, if a filter list detects a script from a known ad server (e.g., Google Ads), it will block that script from executing, preventing the ad from being shown.

How Ad Blockers Impact Web Page Elements and Scripts

Ad blockers not only block ads but also affect other elements on a webpage, including tracking scripts and social media buttons. By removing these elements, ad blockers enhance your online privacy by preventing websites from tracking your activity across different sites.

One of the most significant benefits of using an ad blocker is the improvement in page load speed. Ads, especially large ones, can slow down the loading time of a page. By blocking these elements, the page often loads faster, providing a smoother browsing experience.

However, blocking ads and scripts can sometimes lead to unintended consequences. Some websites rely on ads for revenue, and by blocking them, you may inadvertently prevent some features of the site from working properly, such as videos or embedded content. While this is an understandable concern, many users prefer the trade-off of a faster, ad-free experience.

In conclusion, ad blockers are powerful tools that improve both your privacy and browsing experience by preventing unwanted ads, blocking tracking scripts, and enhancing page load speeds. Whether using a browser extension or a network-level blocker, the technology behind ad blockers ensures a cleaner and faster internet experience.

Benefits of Using Ad Blockers for Privacy and Performance

Ad blockers offer multiple advantages that can significantly improve your online experience. By blocking intrusive ads, preventing tracking, and enhancing security, ad blockers are essential tools for maintaining privacy, boosting browsing speed, and protecting against malicious content. In this section, we’ll explore how ad blockers enhance privacy, performance, and security to create a safer and faster browsing experience.

Protecting Your Privacy: How Ad Blockers Prevent Tracking

One of the primary benefits of using an ad blocker is the protection it offers against online tracking. Ad blockers work by blocking third-party trackers that follow your online activity across websites. These trackers are often embedded in ads and used to collect personal data, such as browsing history, to create targeted advertisements. By blocking these trackers, ad blockers prevent advertisers from building a detailed profile of you based on your online behavior.

For example, when you visit a website, trackers are often embedded in ads that follow you to other sites, collecting data without your consent. An ad blocker can prevent these trackers from loading, ensuring that your browsing activity remains private. This means that you’ll see fewer irrelevant ads and be less exposed to unwanted data collection. The result is a more private and secure browsing experience.

Ad blockers are essential privacy tools that not only prevent tracking but also protect sensitive information from being shared without your knowledge. By using an ad blocker, you can keep your online habits and personal details secure from prying eyes.

Speeding Up Your Browsing Experience by Blocking Intrusive Ads

Ads can significantly slow down your browsing experience. These ads often require large resources to load, and many of them slow down page load times, making your browsing less enjoyable. Ad blockers help by preventing ads from being loaded, which results in faster page load times and an overall smoother browsing experience.

When an ad blocker is activated, it prevents ads such as pop-ups, banners, and video ads from appearing on websites. This can make a noticeable difference in how quickly a page loads. For instance, studies have shown that ad blockers can reduce page load times by up to 30%. By eliminating the need to load bulky advertisements, your web pages will load more quickly, and you’ll have a better browsing experience.

The speed improvement is particularly noticeable on websites filled with heavy advertising. With the ads blocked, the content you want to view loads faster, and you avoid interruptions like auto-playing videos and pop-up ads. Using an ad blocker not only speeds up browsing but also improves overall web performance, allowing you to browse the web with ease.

Improving Security: Preventing Malicious Ads and Pop-ups

Another crucial benefit of ad blockers is enhanced security. Malicious ads, also known as “malvertising,” can be used to deliver malware, phishing scams, or other harmful content to unsuspecting users. These types of ads are often disguised as legitimate content, tricking users into clicking on them and exposing their devices to potential threats.

Ad blockers can prevent these malicious ads from loading, significantly reducing the risk of encountering harmful content. For example, when you visit a site with an ad promoting malicious software or phishing attempts, the ad blocker will prevent it from appearing, ensuring that you are not exposed to potential scams or malware.

This added layer of security is especially important for protecting your personal information. By blocking harmful pop-ups and ads that attempt to trick you into revealing sensitive details, ad blockers provide a safer online environment. Whether it’s blocking a pop-up attempting to steal login credentials or stopping malware from being downloaded, ad blockers play a key role in safeguarding your device and your data.

By configuring your ad blocker settings, you can effectively minimize distractions from ads while ensuring that your personal data remains protected from trackers. In this section, we’ll walk you through the key steps to configure your ad blocker for maximum efficiency and privacy.

Customizing Filter Settings for Maximum Efficiency

To make your browsing experience faster and more enjoyable, you can customize the filter lists in your ad blocker. Filter lists are pre-made sets of rules that block specific types of ads, trackers, or other unwanted content. By selecting the right filter lists, you can ensure that unnecessary ads are blocked without affecting the speed or functionality of websites.

How to Customize Filter Settings:

1. Open your ad blocker’s settings: Most ad blockers, like uBlock Origin or Adblock Plus, allow you to manage filter lists directly in the settings menu.
2. Select filter lists: Choose the filter lists that align with your goals. For example, the “EasyList” filter blocks most common ads, while the “Privacy” or “Tracking Protection” filters are aimed at blocking trackers and improving privacy.
3. Enable/Disable specific lists: In uBlock Origin, go to the “Filter Lists” tab and enable or disable lists by checking or unchecking the boxes next to each list.

By using relevant filter lists, such as EasyList for general ad-blocking or Malware domains to block malicious content, you can maximize your ad blocker’s efficiency and minimize the strain on system resources.

Common Filter Lists to Consider:

Selecting and enabling these lists will help reduce the number of unwanted ads and trackers, improving your browsing speed.

Ensuring Privacy Protection by Blocking Tracking Scripts

One of the key benefits of using an ad blocker is privacy protection. Many websites use tracking scripts to monitor your behavior, collect personal information, and display targeted ads. Blocking these trackers is essential for maintaining your privacy online.

How to Block Tracking Scripts:

1. Enable privacy-focused filter lists: In your ad blocker’s settings, make sure to enable filters designed to block trackers. For example, uBlock Origin offers a “Privacy” filter list specifically aimed at blocking such scripts.
2. Enable “Block third-party scripts”: Many ad blockers have an option to block third-party scripts, which are often used for tracking. This can typically be found under the “Privacy” or “Advanced” settings.

By enabling these settings, you can prevent websites from tracking your online activity, ensuring a more private browsing experience.

Why Privacy Protection Matters: Blocking trackers helps protect you from invasive advertising and can reduce the risk of data being sold to third-party companies. It also ensures your browsing data stays private from advertisers.

Adjusting Ad Blocker Settings for Specific Websites

Sometimes, certain websites may require ads to function properly, or they may not display content correctly when ads are blocked. In these cases, it’s helpful to adjust your ad blocker settings to allow ads on trusted websites or whitelist them entirely.

How to Whitelist a Website:

1. Go to the website you want to whitelist.
2. Click on the ad blocker icon in your browser toolbar.
3. Select “Whitelist” or “Disable on this site”. This will allow the website to display ads and content as intended, without interference from your ad blocker.

For example, many news websites use ads to support free content. Whitelisting such sites ensures you can still enjoy the content while supporting their advertising model.

When to Use Website-Specific Settings:

• If a website is broken or doesn’t display properly due to ad blocking.
• If you trust a site and want to support its ad-based revenue model.

By adjusting your ad blocker for specific sites, you can maintain a balance between blocking unwanted content and ensuring websites function as intended.

Troubleshooting Common Issues with Ad Blockers

Ad blockers are great tools for enhancing your online privacy and improving your browsing experience by removing intrusive ads. However, like any software, they can sometimes cause issues. Whether it’s compatibility problems with websites, conflicts with other extensions, or performance slowdowns, troubleshooting ad blocker issues can seem intimidating. This section will guide you through common problems and offer simple, beginner-friendly solutions to help you get your ad blocker working smoothly again.

Fixing Ad Blocker Compatibility Issues with Websites

One common issue that ad blockers cause is interfering with the display of website content. Sometimes, websites may appear broken, or elements such as images, buttons, or menus might not work properly. This often happens when the ad blocker mistakenly identifies legitimate content as an ad and blocks it.

To resolve compatibility issues with websites, follow these simple steps:

1. Disable Specific Filters: If the ad blocker is blocking important content, it may be due to a specific filter. Open your ad blocker’s settings and look for an option to disable certain filter lists. Start by disabling the most aggressive ones, such as “Social media” or “Anti-adblock,” to see if the issue resolves.
2. Use the Whitelist Feature: If a particular website isn’t working properly, try whitelisting it. Most ad blockers allow you to add sites to a whitelist so that ads and other content on those sites aren’t blocked. You can typically find this option in the ad blocker’s menu by clicking on the extension icon in your browser.
3. Update Your Ad Blocker: Ensure that your ad blocker is up to date. Sometimes, an outdated version of the software can lead to compatibility issues with newer web technologies.

For example, if you visit a site like your bank or a news site and notice some content missing, whitelisting the site can fix the problem without compromising your privacy.

Comparing Docker Installation Methods on Ubuntu: APT vs Manual Setup

When it comes to setting up Docker on Ubuntu, there are two common methods: using the APT package manager or performing a manual installation. Both approaches have their advantages and considerations, depending on your needs and expertise. In this section, we will explore each method, outlining their pros and cons, so you can make an informed decision on which one is best suited for your Docker installation on Ubuntu.

APT Installation: Advantages and Considerations

The APT installation method is the most straightforward way to install Docker on Ubuntu, particularly for beginners. APT (Advanced Package Tool) is the default package manager for Ubuntu, and Docker is included in Ubuntu’s official repositories.

To install Docker using APT, simply run the following command:

sudo apt install docker.io

This command installs Docker from the official Ubuntu repositories, ensuring that you get a stable, tested version of the software. The advantages of this method include:

• Ease of Use: The APT method is incredibly simple, requiring just a single command. It handles dependencies and ensures Docker is correctly installed.
• Security Updates: When you install Docker using APT, your system will automatically receive security updates through the regular Ubuntu update process.
• Compatibility: APT ensures that Docker will work well with your specific version of Ubuntu, as it’s part of the official repository.

However, there are some considerations to keep in mind. APT installs a stable version of Docker, which may not always be the latest version available. If you need the most up-to-date features, you might need to look into other installation methods.

Manual Installation: Pros and Cons

The manual installation method gives you more control over the version of Docker you install. It involves downloading the installation script directly from Docker’s official website and running it on your system. To install Docker manually, use the following commands:

curl -fsSL https://get.docker.com -o get-docker.sh
sudo sh get-docker.sh

This process downloads Docker’s installation script and executes it, installing the latest version of Docker. The advantages of manual installation include:

• Control Over Version: Manual installation allows you to install the latest version of Docker, which might include new features and updates not yet available through APT.
• Flexibility: By choosing manual installation, you can tailor the installation process to your specific needs, including selecting a different version or adjusting configuration settings.

However, manual installation also has some downsides:

• Updates Management: Unlike APT, manual installation does not automatically handle updates. You will need to manually update Docker whenever a new version is released.
• Complexity: The manual installation process may seem a bit more complex, especially for beginners, as it requires fetching a script from an external site.

When to Choose APT vs Manual Setup

Choosing between APT and manual installation depends largely on your needs and experience level.

• APT Installation: If you’re new to Docker or need a simple and reliable installation process, APT is the best choice. It’s quick, easy, and secure, making it ideal for most users, particularly those who are not concerned about having the latest version of Docker.
• Manual Installation: If you need the latest version of Docker with specific features or configuration options, the manual installation method is the way to go. It provides flexibility and control over your setup, but requires more attention to detail, particularly when managing updates.

For most beginner users, APT is the preferred method due to its simplicity and reliability. However, advanced users or those who need the latest Docker features may find manual installation more suitable.

If you’re looking to set up your Docker environment with flexibility, consider exploring how Buy Ubuntu VPS: Say Goodbye to Hidden Costs with Caasify can help. Caasify’s flexible scaling options allow you to easily adjust resources as your Docker environment grows, providing the scalability you need to run your applications efficiently.

Optimizing Docker on Ubuntu: Best Practices for Performance and Scalability

Optimizing Docker on Ubuntu is crucial for achieving better performance and scalability, especially when managing multiple containers. By making a few simple adjustments, you can significantly improve the speed and resource usage of your Docker containers. Whether you are running applications in a development environment or preparing for a production workload, these tips will help you enhance the overall performance and scalability of your Docker setup.

Configuring Docker for Performance Tuning

To optimize Docker on Ubuntu, the first step is to configure Docker’s resources to ensure containers run efficiently. Limiting resources like CPU and memory helps avoid overconsumption, leading to faster and more stable operations.

• Limit CPU and Memory Usage: Use the docker run command to set resource limits for each container. For example:

docker run --memory="512m" --cpus="1" my_container

This command limits the container to 512 MB of memory and 1 CPU core. By managing resources this way, you ensure that containers do not consume excessive CPU or memory, which can slow down your system.

• Optimize Storage Drivers: Docker uses storage drivers to manage container images and file systems. For optimal performance on Ubuntu, use the overlay2 storage driver if your system supports it:

"storage-driver": "overlay2"

The overlay2 driver is generally faster and more efficient than other options. To set this, edit the Docker configuration file at /etc/docker/daemon.json and include the line above.

By configuring resource limits and optimizing the storage driver, you can improve Docker’s performance on Ubuntu significantly.

Setting Up Docker for Scalability on Ubuntu

Scaling Docker containers allows you to run multiple instances of an application across different containers. Docker Compose makes this process much easier by allowing you to define multi-container environments in a simple configuration file.

• Using Docker Compose for Scaling: Here is an example of a basic docker-compose.yml file for setting up a web and database service:

version: '3'
services:
  web:
    image: nginx
    ports:
      - "80:80"
  db:
    image: mysql
    environment:
      MYSQL_ROOT_PASSWORD: example

This file defines two services: a web service using the Nginx image and a database service using the MySQL image. With Docker Compose, you can scale these services up or down with a simple command:

docker-compose up --scale web=3

This command will scale the web service to run 3 containers. Docker Compose is an easy way to manage multiple containers on Ubuntu, making it simpler to scale your applications as needed.

Docker Container Networking and Optimization

Optimizing Docker container networking ensures that your containers can communicate efficiently with each other and the outside world. By configuring networks properly, you improve security and performance.

• Creating Custom Networks: To optimize communication between containers, you can create a custom bridge network:

docker network create --driver bridge my_network

This command creates a custom network named my_network using the bridge driver, which is the default network mode. Containers attached to this network can communicate with each other more securely and efficiently.

By setting up custom networks, you can ensure containers interact smoothly, reducing latency and potential bottlenecks.

Leveraging Caasify’s Global Infrastructure for Docker Performance

For optimal performance and scalability, leveraging cloud-based infrastructure like Caasify’s global network can greatly enhance your Docker setup on Ubuntu. Cloud infrastructure offers benefits such as improved uptime, fast access to resources, and the ability to scale on demand.

By using a platform like Caasify, you can offload infrastructure management, ensuring your Docker containers are running on high-performance servers with global reach. This helps maintain consistent performance even during traffic spikes, making it an excellent choice for Docker users who need reliable and scalable solutions.

With these best practices, you are now equipped to optimize Docker on Ubuntu for both performance and scalability. Whether you’re managing a small application or scaling a large project, these tips will help you achieve a smoother and more efficient Docker experience.

Introduction

When working with Node.js, generating unique resource IDs with base32 encoding and checksum verification ensures data integrity and security. This process involves creating identifiers from random bytes, encoding them using base32, and appending a checksum to verify their accuracy and prevent tampering. Whether you’re building APIs or managing databases, these techniques help ensure that each ID remains unique, readable, and permanent. In this tutorial, we’ll walk through the steps to create and validate these resource IDs using Node.js, base32 encoding, and checksum calculations.

Step 1 — Generating an Encoded ID

In this step, you will write a function to generate an identifier from random bytes into a unique alphanumeric string. Your identifier will be encoded using base32 encoding, but it will not have a checksum affiliated until later in the tutorial. The encoding process will create a unique identifier of a specified length based on the number of bytes you choose, building an ID that incorporates some of the characteristics of a good ID.

Start by making a new folder for this project, then move into that folder:

$ mkdir checksum
$ cd checksum

The project folder will be called checksum for this tutorial. Create and open a package.json file in your project folder (using your favorite editor):

$ nano package.json

Then add the following lines of code:

{
“name”: “checksum”,
“version”: “1.0.0”,
“main”: “index.js”,
“type”: “module”
}

In this file, you define the project name as checksum, and you consider the code version “1.0.0”. You define the main JavaScript file as index.js. When you have “type”: “module” in the package.json file, your source code should use import syntax. In this file, you use the JSON data format, which you can learn more about in How to Work with JSON in JavaScript. Save and close the file.

You’ll use a few Node.js modules to generate the ID: crypto and base32-encode, with its corresponding decoder base32-decode. The crypto module is packaged with Node.JS, but you will need to install base32-encode and base32-decode for use later in this tutorial. Encoding is putting a sequence of characters (letters, numbers, punctuation, and certain symbols) into a specialized format for efficient transmission or storage. Decoding is the opposite process: converting an encoded format back into the original sequence of characters. Base32 encoding uses a 32-character set, which makes it a textual 32-symbol notation for expressing numbers.

In a terminal session, install these module packages in the project folder with the following command:

$ npm i base32-encode base32-decode

You will receive an output that indicates these modules have been added:

added 3 packages, and audited 5 packages in 2s
found 0 vulnerabilities

If you encounter issues during installation, you can refer to How To Use Node.js Modules with npm and package.json for support. Still in your project folder, create a new file called index.js:

$ nano index.js

Add the following lines of JavaScript code to the index.js file:

import crypto from ‘crypto’;
import base32Encode from ‘base32-encode’;
import base32Decode from ‘base32-decode’;

function generate_Id(byte_size) {
const bytes = crypto.randomBytes(byte_size);
return base32Encode(bytes, ‘Crockford’);
}

console.log(‘ID for byte size = 1:’, generate_Id(1), ‘n’);
console.log(‘ID for byte size = 12:’, generate_Id(12), ‘n’);
console.log(‘ID for byte size = 123:’, generate_Id(123), ‘n’);

The import command loads the required modules. To generate bytes from the number, you define a generate_Id function to take the bytes’ size of bytes and then create random bytes of this size using the randomBytes function from the crypto module. The generate_Id function then encodes these bytes using the Crockford implementation of base32 encoding. For instructional purposes, a few IDs are generated and then logged to the console. The base32-decode module will be used to decode the resource ID in the next steps.

Save your index.js file, then run the code in a terminal session with this command:

$ node index.js

You will receive an output response similar to this:

ID for byte size = 1: Y8
ID for byte size = 12: JTGSEMQH2YZFD3H35HJ0
ID for byte size = 123: QW2E2KJKM8QZ7174DDB1Q3JMEKV7328EE8T79V1KG0TEAE67DEGG1XS4AR57FPCYTS24J0ZRR3E6TKM28AM8FYZ2AZTZ55C9VVQTABE0R7QRH7QBY7V3GBYBNN5D9JK0QMD9NXSWZN95S0772DHN43Q003G0QNTPA2J3AFA3P7Q167C1VNR92Z85PCDXCMEY0M7WA

Your ID values might differ due to the randomness of generated bytes. The generated ID may be shorter or longer in length, depending on the byte size you select. Back in index.js, comment out the console outputs using the JavaScript commenting feature (adding a double slash // before the line):

//console.log(‘ID for byte size = 1:’, generate_Id(1), ‘n’);
//console.log(‘ID for byte size = 12:’, generate_Id(12), ‘n’);
//console.log(‘ID for byte size = 123:’, generate_Id(123), ‘n’);

These lines demonstrate how encoding will output different identifiers based on the bytes associated. Because these lines will not be used in the following sections, you can comment them out as demonstrated in this code block or delete them entirely. In this step, you created an encoded ID by encoding random bytes. In the next step, you will combine the encoded bytes and a checksum, creating a unique identifier.

Step 2 — Generating a Resource Identifier

Now you will create an ID with a checksum character. Generating the checksum character is a two-step process. For instructional purposes, each function that creates the composite function will be built separately in the following subsections. First, you will write a function that runs a modulo operation. Then, you will write another function that maps the results to a checksum character, which is how you will generate the checksum for your resource ID. Finally, you will verify the identifier and checksum to ensure that the resource identifier is accurate.

Step 3 — Running a Modulo Operation

In this section, you will convert the bytes corresponding to the number ID to a number between 0-36 (limits inclusive, which means any number between 0 to 36, including 0 and 36). The bytes corresponding to the number ID are converted to an integer as a result of a modulo operation. The modulo operation will return the remainder of the dividend obtained by converting the bytes to BigInteger (BigInt) values. To implement this procedure, add the following lines of code to the bottom of the index.js file:

function calculate_checksum(bytes) {
const intValue = BigInt(`0x${bytes.toString(‘hex’)}`);
return Number(intValue % BigInt(37));
}

The function calculate_checksum works with the bytes defined earlier in the file. This function will convert bytes to hexadecimal values, which are further converted to BigInteger BigInt values. The BigInt data type represents numbers greater than those represented by the primitive data type number in Javascript. For example, although integer 37 is relatively small, it is converted to BigInt for the modulo operation. To achieve this conversion, you first set the intValue variable with the BigInt conversion method, using the toString method to set bytes to hex. Then, you return a numerical value with the Number constructor, in which you run the modulo operation with the % symbol to find the remainder between the intValue and BigInt using the sample value of 37. That integer value (in this example, 37) acts as an index to select an alphanumeric character from a custom-built string of alphanumeric characters. If intValue value is 123 (depending on the bytes), the module operation will be 123 % 37. The result of this operation with 37 as the integer value will be a remainder of 12 and a quotient of 3. With a value of 154 for the resource ID, the operation 154 % 37 will result in a remainder of 6. This function maps the incoming bytes to the modulo result.

Step 4 — Obtaining a Checksum Character

After obtaining the modulo result in the previous section, you can map it to a checksum character. Add the following lines of code to the index.js file just below the previous code:

function get_checksum_character(checksumValue) {
const alphabet = ‘0123456789ABCDEFG’ + ‘HJKMNPQRSTVWXYZ*~$=U’;
return alphabet[Math.abs(checksumValue)];
}

For the function get_checksum_character, you call checksumValue as a parameter. Within this function, you define a string constant named alphabet as a custom-built string of alphanumeric characters. Depending on the value set for the checksumValue, this function will return a value that pairs the defined string from the alphabet constant with the absolute value of the checksumValue.

Step 5 — Generating ID with Checksum

Next, you will write a function that uses the two functions written in these sections to generate an ID from the encoding of bytes combined with a checksum character. Add the following lines of code to the index.js file:

function generate_Id_with_checksum(bytes_size) {
const bytes = crypto.randomBytes(bytes_size);
const checksum = calculate_checksum(bytes);
const checksumChar = get_checksum_character(checksum);
console.log(“checksum character: “, checksumChar);
const encoded = base32Encode(bytes, ‘Crockford’);
return encoded + checksumChar;
}

const Hotel_resource_id = generate_Id_with_checksum(132);
console.log(“Hotel resource id: “, Hotel_resource_id);

Step 6 — Verifying the ID

The verify_Id function checks the integrity of the ID by checking the checksum. The remaining characters of the identifier are decoded into a buffer, and then calculate_checksum and get_checksum_character are run subsequently on this buffer to extract the checksum character for the comparison (with calculated_checksum_char == checksum_char).

Step 7 — Altering the Identifier for a Non-matching Result

You will now alter the value for the identifier to check if the checksums will get matched. The alteration in this step will always result in a non-matching checksum, as the integrity is not maintained if any character in the ID is manipulated. An alteration like this may result from transmission errors or malicious behavior. This alteration is for instructional purposes and is not recommended for production builds but will enable you to assess a non-matching checksum result.

You can learn more about generating unique identifiers and checksums in programming through this detailed guide on Node.js Resource ID Generation and Checksum Techniques.

Conclusion

In conclusion, generating unique resource IDs with a checksum in Node.js using base32 encoding is a powerful method for ensuring data integrity and security. By creating an identifier from random bytes, encoding it, and appending a checksum for verification, you can guarantee that the ID remains unaltered and reliable. This process highlights key qualities like uniqueness, readability, and permanence, which are essential for any robust API or data management system. As you apply these techniques, remember that leveraging base32 encoding and checksum verification is crucial in maintaining secure, tamper-proof identifiers in your applications. Looking ahead, these practices will continue to evolve as the demand for secure and scalable systems grows, particularly in API development and database management.

Introduction

Setting up a cloud-based IDE like code-server on Ubuntu can drastically improve your development workflow by providing a consistent environment accessible from any device. With Nginx as a reverse proxy and Let’s Encrypt securing the connection, you can ensure a smooth, reliable, and secure experience while using Visual Studio Code remotely. In this guide, we’ll walk you through the step-by-step process of installing and configuring code-server on Ubuntu 22.04, securing it with Let’s Encrypt certificates, and making it accessible via your own domain. By the end, you’ll have a fully functional, cloud-powered development environment that works seamlessly from anywhere.

Step 1 — Installing code-server

In this step, you’ll set up code-server on your server by downloading the latest version and creating a systemd service that will keep code-server running in the background. You’ll also set up a restart policy for the service, so if code-server crashes or the server reboots, it’ll start right back up. All the data related to code-server will be saved in a folder named ~/code-server.

To create this folder, run:

mkdir ~/code-server

Now, navigate to the folder:

cd ~/code-server

You’ll need the latest Linux build of code-server from its Github releases (it’ll have “linux” in the filename). At the time I’m writing this, the latest version is 4.8.2. To download it, use the command:

wget https://github.com/coder/code-server/releases/download/v4.8.2/code-server-4.8.2-linux-amd64.tar.gz

Once the download finishes, unpack the archive with this command:

tar -xzvf code-server-4.8.2-linux-amd64.tar.gz

This will create a folder with the same name as the archive. This folder contains all the source code for code-server. To make it available system-wide, run the following command to copy it to /usr/lib/code-server:

sudo cp -r code-server-4.8.2-linux-amd64 /usr/lib/code-server

Now, create a symbolic link so that you can run code-server from anywhere:

sudo ln -s /usr/lib/code-server/bin/code-server /usr/bin/code-server

Next, you’ll need to create a directory where code-server will store user data. To do this, run:

sudo mkdir /var/lib/code-server

With code-server downloaded and made globally accessible, you’ll now set up a systemd service to keep it running in the background. You’ll store the service configuration in a file called code-server.service in the /lib/systemd/system directory (where systemd stores all its services). To create it, open your text editor (this example uses nano):

sudo nano /lib/systemd/system/code-server.service

Now, add the following lines to the file:

[Unit]
Description=code-server
After=nginx.service
[Service]
Type=simple
Environment=PASSWORD=your_password
ExecStart=/usr/bin/code-server –bind-addr 127.0.0.1:8080 –user-data-dir /var/lib/code-server –auth password
Restart=always
[Install]
WantedBy=multi-user.target

This section specifies that the service depends on nginx (meaning nginx must be up and running before code-server starts). It also defines how the service should run and what parameters it should use. For example, –bind-addr 127.0.0.1:8080 binds the code-server to localhost, so it’s only accessible within the server itself. –user-data-dir sets the user data directory. –auth password means that anyone trying to access code-server will need a password, which you can set in the PASSWORD environment variable. Don’t forget to replace your_password with your desired password. The Restart=always directive ensures code-server will restart automatically in case of a failure or system reboot. The [Install] section tells systemd to start the service when the server logs in. After that, save and close the file.

Start the code-server service by running:

sudo systemctl start code-server

To make sure it’s running correctly, check the status:

sudo systemctl status code-server

You should see an output similar to this:

● code-server.service – code-server
Loaded: loaded (/lib/systemd/system/code-server.service; disabled; preset: enabled)
Active: active (running) since Thu 2022-11-03 12:39:26 UTC; 5s ago
Main PID: 2670 (node)
Tasks: 22 (limit: 1116)
Memory: 90.9M
CPU: 799ms
CGroup: /system.slice/code-server.service
├─2670 /usr/lib/code-server/lib/node /usr/lib/code-server –bind-addr 127.0.0.1:8080 –user-data-dir /var/lib/code-server –auth password
└─2692 /usr/lib/code-server/lib/node /usr/lib/code-server/out/node/entry

To make sure code-server starts up automatically after a reboot, run this command to enable it:

sudo systemctl enable code-server

The output should indicate that a symlink was created:

Created symlink /etc/systemd/system/multi-user.target.wants/code-server.service → /lib/systemd/system/code-server.service.

With code-server set up and enabled to start at boot, you can now expose it to the web by configuring nginx to act as a reverse proxy.

Step 2 — Exposing code-server at Your Domain

Now that code-server is up and running, you’ll want to make it accessible through your domain. For this, you’ll use nginx as a reverse proxy. You’ve probably already dealt with nginx configuration files in a previous step. These configuration files are stored under /etc/nginx/sites-available and need to be symlinked to /etc/nginx/sites-enabled to activate them.

Start by creating a new configuration file for code-server in /etc/nginx/sites-available. You can do that with your preferred text editor:

sudo nano /etc/nginx/sites-available/code-server.conf

Now, add the following lines:

server {
listen 80;
listen [::]:80;
server_name code-server.your-domain;
location / {
proxy_pass http://localhost:8080/; 
proxy_set_header Upgrade $http_upgrade; 
proxy_set_header Connection upgrade; 
proxy_set_header Accept-Encoding gzip; 
}
}

In this file, replace code-server.your-domain with your actual domain. The server block tells nginx to listen on port 80 for incoming HTTP requests. The server_name directive tells nginx to apply this configuration to your specific domain. The location block passes all incoming requests to the code-server running on localhost at port 8080. The proxy_set_header directives carry over important HTTP headers, necessary for the correct functioning of WebSockets that code-server relies on.

Once you’ve added the configuration, save and close the file. Now you need to activate this site configuration by creating a symlink from /etc/nginx/sites-available to /etc/nginx/sites-enabled:

sudo ln -s /etc/nginx/sites-available/code-server.conf /etc/nginx/sites-enabled/code-server.conf

Test the validity of your configuration with:

sudo nginx -t

You should see an output like this:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

For the changes to take effect, restart nginx:

sudo systemctl restart nginx

Now, you should be able to access code-server through your domain. Next, you’ll secure your domain with a free Let’s Encrypt TLS certificate.

Step 3 — Securing Your Domain

Now that your domain is properly set up, let’s make sure it’s secure by using a Let’s Encrypt TLS certificate. You’ll use Certbot to get the certificate and configure it for your domain. Once done, your code-server will be running behind HTTPS.

Before proceeding, you’ve probably already enabled ufw (Uncomplicated Firewall) and set it up to allow unencrypted HTTP traffic. To allow encrypted traffic, run the following command:

sudo ufw allow https

You should see an output like this:

Rule added
Rule added (v6)

Just like with nginx, you’ll need to reload ufw for the change to take effect:

sudo ufw reload

Once that’s done, navigate to your domain in a web browser. The code-server login prompt should appear. Enter the password you set earlier, and you’ll be taken directly to the editor GUI.

Now that code-server is properly exposed, you can request Let’s Encrypt TLS certificates to secure it. Start by installing Certbot and the nginx plugin:

sudo apt install certbot python3-certbot-nginx -y

Then, to request a certificate for your domain, run:

sudo certbot –nginx -d code-server.your-domain

Certbot will ask for your email address (in case they need to notify you about any certificate-related issues) and to agree to the terms of service. After that, it’ll automatically configure nginx to support HTTPS and request the certificate. You should see an output like this:

Requesting a certificate for code-server.your-domain
Successfully received certificate.
Certificate is saved at: /etc/letsencrypt/live/code-server.your-domain/fullchain.pem
Key is saved at: /etc/letsencrypt/live/code-server.your-domain/privkey.pem
The certificate will expire on 2023-02-01, but don’t worry—Certbot will automatically renew it in the background.

The certificate is now deployed, and your site is secured! You’ll see the padlock icon in the browser, indicating that your connection is secure. Congratulations! Your code-server is now live and secure on your domain.

Introduction

Building a REST API with Prisma, PostgreSQL, TypeScript, and Express is an essential skill for modern web development. With the power of Prisma ORM and PostgreSQL, you can efficiently manage data models and database queries, while TypeScript ensures type safety and scalability. In this guide, we’ll walk you through the process of setting up your environment, creating and migrating your database schema, and implementing CRUD operations for a blogging application. Additionally, you’ll learn how to leverage Express to handle API routes, making your development process faster and more efficient. Let’s dive into building a robust and scalable REST API for your app.

Step 1 — Creating Your TypeScript Project

Alright, in this step, we’re going to set up a basic TypeScript project using npm. This will be the foundation for building your REST API in the tutorial. First things first, let’s create a new folder for your project. You can do this by running this command in your terminal:

$ mkdir my-blog

Now, move into that folder and initialize an empty npm project. You’ll notice that the -y flag will skip all those pesky prompts that normally pop up when you run npm init. This means npm will create the project with default settings. But, if you’re feeling adventurous and want to customize things manually, just skip the -y flag when you run the command. Here’s what you need to do next:

$ cd my-blog
$ npm init -y

Once you’ve done this, you’ll see something like this in your terminal output. It’s the default configuration of your new npm project:

Wrote to /…/my-blog/package.json:
{
“name”: “my-blog”,
“version”: “1.0.0”,
“description”: “”,
“main”: “index.js”,
“scripts”: {
“test”: “echo “Error: no test specified” && exit 1″
},
“keywords”: [],
“author”: “”,
“license”: “ISC”
}

Basically, this command creates a simple package.json file, which is like the instruction manual for your npm project. At this point, we’re ready to add TypeScript to your project. So, run this next command to install TypeScript, ts-node, and @types/node as development dependencies:

$ npm install typescript ts-node @types/node –save-dev

Here’s a quick breakdown of what’s happening:

• typescript: The TypeScript toolchain that will convert your TypeScript code into JavaScript.
• ts-node: This allows you to run your TypeScript code directly, without needing to first compile it to JavaScript manually.
• @types/node: This is like the Rosetta Stone for TypeScript, ensuring that TypeScript knows how to talk to Node.js and its built-in modules.

Next, let’s set up your tsconfig.json file. This file makes sure TypeScript is properly configured for your project. You can create it by running:

$ nano tsconfig.json

In the newly opened file, add this JSON code:

{
“compilerOptions”: {
“sourceMap”: true,
“outDir”: “dist”,
“strict”: true,
“lib”: [“esnext”],
“esModuleInterop”: true
}
}

After you’ve added this, save the file and close it. Now, let’s break down what this configuration does:

• sourceMap: This makes sure you can debug your TypeScript code easily by letting you trace it back to its original source in the browser or debugging tools.
• outDir: This tells TypeScript where to put the compiled JavaScript files. Here, we’ve set it to a folder named dist.
• strict: This turns on TypeScript’s strict type-checking, which helps you catch bugs earlier in development.
• lib: This includes the latest JavaScript features (think ECMAScript), so you’re all set for modern JavaScript.
• esModuleInterop: This makes it easier for TypeScript to play nice with different module systems (like CommonJS and ES Modules), which is really useful in Node.js.

This setup might be basic, but it’s a solid foundation to get you started. If you want to dive deeper into the specific settings in the tsconfig.json file, you can check out the official TypeScript documentation.

Now that your TypeScript project is ready to roll, the next step is to set up your PostgreSQL database using Docker and link it up with Prisma, a really cool ORM (Object-Relational Mapping) tool. Let’s get into that next!

Read more about setting up TypeScript projects and managing dependencies in the official guide TypeScript Configuration Options.

Step 2 — Setting Up Prisma with PostgreSQL

In this step, we’re going to install the Prisma CLI, create the first version of your Prisma schema file, set up PostgreSQL using Docker, and connect Prisma to PostgreSQL. The Prisma schema file is basically the main blueprint for your Prisma setup. It will define how your database is structured.

To start, let’s install the Prisma CLI in your project. You can do that with the following command:

$ npm install prisma –save-dev

Now, here’s a tip: It’s better to install the Prisma CLI locally in your project rather than globally. This is because if you’re working on multiple Prisma projects, having a local version of Prisma in each project avoids version conflicts. This way, each project will use its own specific version of the Prisma CLI.

Next up, we’ll set up your PostgreSQL database using Docker. You’ll need to create a docker-compose.yml file to configure and launch your database container. To make this file, run the following command:

$ nano docker-compose.yml

Then, add the following configuration inside the file:

version: ‘3.8’
services:
postgres:
image: postgres:10.3
restart: always
environment:
– POSTGRES_USER=sammy
– POSTGRES_PASSWORD=your_password
volumes:
– postgres:/var/lib/postgresql/data
ports:
– ‘5432:5432’
volumes:
postgres:

This docker-compose.yml file configures a PostgreSQL database that will run in a Docker container. It sets up the database to be accessed through port 5432. The database credentials are set as sammy for the username and your_password for the password. You can, of course, change these values to whatever you prefer. After you’re done, save the file and exit.

Now, we’re ready to launch the PostgreSQL container. To do that, run the following command:

$ docker-compose up -d

What this command does is pull the image from Docker Hub, create a container, and start the PostgreSQL database. The terminal output will look like this:

Pulling postgres (postgres:10.3)…
10.3: Pulling from library/postgres
f2aa67a397c4: Pull complete
6de83ca23e55: Pull complete
…
Status: Downloaded newer image for postgres:10.3
Creating my-blog_postgres_1 … done

To make sure everything is working, you can verify the status of your PostgreSQL container by running this command:

$ docker ps

This will show you the list of active containers. You should see your PostgreSQL container listed, along with its status and port mappings. It’ll look something like this:

CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
8547f8e007ba postgres:10.3 “docker-entrypoint.s…” 3 seconds ago Up 2 seconds 0.0.0.0:5432->5432/tcp my-blog_postgres_1

Now that the PostgreSQL container is running, let’s move on to setting up Prisma. In your terminal, run this command to initialize Prisma in your project:

$ npx prisma init

After running this, you’ll see an output like this:

✔ Your Prisma schema was created at prisma/schema.prisma. You can now open it in your favorite editor.

Here’s a quick note: It’s a good idea to always use npx to run Prisma commands, so you’re using the version of Prisma that’s installed locally in your project. After running this command, Prisma will create a prisma folder in your project directory. Inside that folder, you’ll find the schema.prisma file, which is where your data model will go.

Along with the schema.prisma file, Prisma will also generate a .env file in the root of your project. This file will contain the environment variables for your project, including the database connection URL. To update that connection URL, open the .env file with this command:

$ nano .env

Then, change the DATABASE_URL to match your locally running PostgreSQL database. Here’s how it should look:

DATABASE_URL=”postgresql://sammy:your_password@localhost:5432/my-blog?schema=public”

Make sure to replace sammy and your_password with the actual username and password you set in the Docker Compose file. Once you’re done, save and close the .env file.

Congrats! You’ve now successfully set up PostgreSQL using Docker, installed the Prisma CLI, and connected Prisma to your PostgreSQL database through the .env file. The next step will be to define your data model in Prisma and create the corresponding database tables.

For more on setting up Prisma with PostgreSQL and using it effectively, check out this comprehensive guide on Connecting Prisma with PostgreSQL.

Step 3 — Defining Your Data Model and Creating Database Tables

In this step, you’ll define your data model in the Prisma schema file. This is where you lay out how you want your database to look. Afterward, we’ll use Prisma Migrate to translate your model into SQL and create the corresponding database tables.

So, since you’re building a blogging application, the two main pieces of data you’ll need are users and posts. Prisma makes it easy to define how these entities should relate to each other with its own data modeling language. This language lets you lay things out in a simple, clear way.

To start, open up the schema.prisma file that was created during the Prisma setup. You can open it by running this:

$ nano prisma/schema.prisma

Now, in this file, we’re going to define two models: User and Post. Each model represents a key part of your app. The fields inside each model correspond to the properties of the user and post, like name, email, content, and so on. Here’s how you’ll define the two models:

model User {
id Int @default(autoincrement()) @id
email String @unique
name String?
posts Post[]
}

model Post {
id Int @default(autoincrement()) @id
title String
content String?
published Boolean @default(false)
author User? @relation(fields: [authorId], references: [id])
authorId Int?
}

Here’s a quick rundown of what each model does:

• The User model has an auto-incrementing id, a unique email field, an optional name field, and a list of posts. The posts field links a user to multiple posts—more on that in a sec.
• The Post model has an auto-incrementing id, a title, optional content, a published field (defaulting to false), and an author field that links each post to a user. The authorId field is used to connect the post to a specific user.

The magic here is the relationship: A user can have many posts, but each post can only have one author. This is called a one-to-many relationship, and it’s represented by the posts field in the User model and the author field in the Post model.

Once you’ve added these models to the schema.prisma file, save and exit.

Now, we’re going to create the corresponding database tables based on these models using Prisma Migrate. To do this, you’ll run the following command:

$ npx prisma migrate dev –name init

What this command does is generate a new SQL migration and apply it to the database. The –name init part just names the migration—this helps keep things organized. You’ll see something like this in your terminal output:

Environment variables loaded from .env
Prisma schema loaded from prisma/schema.prisma
Datasource “db”: PostgreSQL database “my-blog”, schema “public” at “localhost:5432”
PostgreSQL database my-blog created at localhost:5432
The following migration(s) have been created and applied from new schema changes:
migrations/
└─ 20201209084626_init/
└─ migration.sql
Running generate… (Use –skip-generate to skip the generators)
✔ Generated Prisma Client (2.13.0) to ./node_modules/@prisma/client in 75ms

After running the migration, Prisma will create a migration file in the prisma/migrations/ folder. The file will contain all the SQL commands needed to create the tables and set up the relationships. It’ll look something like this:

— CreateTable
CREATE TABLE “User” (
“id” SERIAL,
“email” TEXT NOT NULL,
“name” TEXT,
PRIMARY KEY (“id”)
);

— CreateTable
CREATE TABLE “Post” (
“id” SERIAL,
“title” TEXT NOT NULL,
“content” TEXT,
“published” BOOLEAN NOT NULL DEFAULT false,
“authorId” INTEGER,
PRIMARY KEY (“id”)
);

— CreateIndex
CREATE UNIQUE INDEX “User.email_unique” ON “User”(“email”);

— AddForeignKey
ALTER TABLE “Post”
ADD FOREIGN KEY(“authorId”) REFERENCES “User”(“id”) ON DELETE SET NULL ON UPDATE CASCADE;

This SQL migration creates the User and Post tables, along with a foreign key relationship between the two, so that posts are linked to their authors.

Finally, Prisma also generates the Prisma Client in this step. You’ll use this Prisma Client to interact with your database later on, so it’s all set up and ready for you to start making queries.

At this point, you’ve successfully defined your data model and created the necessary tables in the database. In the next step, you’ll install Prisma Client into your project, so you can query your database easily.

For more on defining data models and creating database tables with Prisma, you can explore this in-depth guide on Prisma Data Modeling and Schema Design.

Step 4 — Exploring Prisma Client Queries in a Plain Script

Prisma Client is like your new best friend when it comes to interacting with your database in Node.js or TypeScript applications. It’s an auto-generated and type-safe query builder that makes it easier to work with databases, replacing older tools like Object-Relational Mappers (ORMs), custom data access layers, or plain SQL queries. You’ll be using Prisma Client to handle all the database operations in your REST API routes.

But before we dive into setting up those routes for your API, let’s first get a feel for how Prisma Client works by writing some basic queries. These queries will help you understand how Prisma connects with your database and how to use it effectively. So, in this step, we’ll write a plain script to experiment with Prisma Client and run some queries.

Installation and Setup

Let’s get started by installing Prisma Client in your project folder. You can do this by running the following command:

$ npm install @prisma/client

Next, create a new folder called src where you’ll store all your source files:

$ mkdir src

Now, inside the src folder, create a TypeScript file named index.ts:

$ nano src/index.ts

This is where you’ll write your script to interact with Prisma Client.

Code Structure

Prisma Client queries always return promises, so you’ll need to use async/await to handle them properly. What this means is that you need to wrap your Prisma Client queries inside an asynchronous function. Below is a basic template that will get you started:

import { PrismaClient } from ‘@prisma/client’

const prisma = new PrismaClient()

async function main() {
// … your Prisma Client queries will go here
}

main()
.catch((e) => console.error(e))
.finally(async () => await prisma.$disconnect())

Explanation of the Boilerplate

Let’s break it down:

• Importing PrismaClient: You bring in PrismaClient from the @prisma/client package you just installed.
• Creating Prisma Client Instance: You create an instance of PrismaClient, which allows you to interact with your database. This instance is named prisma.
• Async Function: The main() function is where your queries will live. Since Prisma queries return promises, you need to mark this function as async.
• Error Handling: If something goes wrong inside the main() function, it will be caught and logged by .catch().
• Closing Database Connection: After your queries are finished, Prisma Client gracefully closes the connection with .finally(async () => await prisma.$disconnect()).

Adding Queries to the Script

Now that you’ve got the boilerplate set up, it’s time to actually start adding some queries. Below is an example of how you can create a new user and also fetch all users from the database:

import { PrismaClient } from ‘@prisma/client’

const prisma = new PrismaClient()

async function main() {
// Create a new user and a related post in one query
const newUser = await prisma.user.create({
data: {
name: ‘Alice’,
email: ‘[email protected]’,
posts: {
create: {
title: ‘Hello World’,
},
},
},
})
console.log(‘Created new user: ‘, newUser)

// Fetch all users with their posts
const allUsers = await prisma.user.findMany({
include: { posts: true },
})
console.log(‘All users: ‘)
console.dir(allUsers, { depth: null })
}

main()
.catch((e) => console.error(e))
.finally(async () => await prisma.$disconnect())

Breakdown of the Queries

Here’s a closer look at what’s happening in these two queries:

• Create Query: prisma.user.create(): This creates a new user in the database. The data object contains the user’s details (name and email). Inside the data object, we also create a post for this user with the title “Hello World”. This is done using Prisma’s nested write query (posts.create).
• Find Query: prisma.user.findMany(): This query fetches all user records from the database. The include: { posts: true } option makes sure that for each user, the associated posts are also fetched (because of the relationship between User and Post).

Running the Script

After you’ve added your queries, save and close the file. To run the script, use the following command in your terminal:

$ npx ts-node src/index.ts

Expected Output

Once the script runs successfully, you’ll see output like this in your terminal:

Created new user: { id: 1, email: ‘[email protected]’, name: ‘Alice’ }
[ { id: 1, email: ‘[email protected]’, name: ‘Alice’, posts: [ { id: 1, title: ‘Hello World’, content: null, published: false, authorId: 1 } ] } ]

• Created User: The first part of the output shows the newly created user, including their ID, email, and name.
• Fetched Users: The second part lists all users, including their posts. In this case, Alice has a post titled “Hello World” linked to her.

Validation

If you’re using a database GUI (like pgAdmin for PostgreSQL), you can double-check that the data was added by looking at the User and Post tables. Or, if you want to use Prisma’s own tool, you can launch Prisma Studio by running:

$ npx prisma studio

Now you’ve used Prisma Client to both read and write data to your database. In the next steps, you’ll implement the routes for your REST API to interact with this data programmatically.

To dive deeper into Prisma Client queries and how to use them effectively, check out the comprehensive guide on Using Prisma Client for Data Queries.

Step 5 — Implementing Your First REST API Route

In this step, you’re going to install and set up Express in your app. Express is a really popular web framework for Node.js that will help you build your REST API routes. The first route we’re going to build is a simple GET request that lets you fetch all users from your API. You’ll pull the user data from your PostgreSQL database using Prisma Client, which we already set up in earlier steps.

Installing Express and Dependencies

First thing’s first, let’s install Express into the project with the following command:

$ npm install express

Since we’re working with TypeScript, you also need to install the corresponding TypeScript type definitions for Express. These types help TypeScript understand and check your code for Express. Install these types using this command:

$ npm install @types/express –save-dev

Setting Up Your Express Application

Now that we’ve got the necessary dependencies installed, it’s time to set up Express in your app. Let’s open the main source file, usually index.ts, and start editing. Open it like this:

$ nano src/index.ts

If there’s any code already in this file, feel free to delete it and replace it with the following to kick-start your REST API server:

import { PrismaClient } from ‘@prisma/client’
import express from ‘express’

const prisma = new PrismaClient()
const app = express()

app.use(express.json()) // Middleware to parse JSON bodies
// … your REST API routes will go here

app.listen(3000, () => console.log(‘REST API server ready at: http://localhost:3000’))

Breakdown of the Code

Let’s break down what’s going on here:

• Import PrismaClient and Express: First, we import the necessary modules. We bring in PrismaClient from the Prisma Client library and express from the Express library.
• Creating an Instance of PrismaClient: We create an instance of PrismaClient, called prisma, which we’ll use to interact with the database.
• Creating the Express App: Calling express() gives us an instance of the Express app, stored in the app variable. This is the main thing that handles incoming requests.
• Middleware to Parse JSON: The line app.use(express.json()) tells Express to properly handle JSON data that comes in with requests. This is pretty important since you’ll likely be dealing with JSON in your requests.
• Start the Server: app.listen(3000) starts the server and listens on port 3000. Once it’s running, it’ll log a message to the console, so you know the server is ready to accept requests at http://localhost:3000.

Implementing the /users Route

Now that your server is set up, it’s time to create the /users route, which will allow you to fetch all users from your database. Add this code between app.use(express.json()) and app.listen():

app.use(express.json())

app.get(‘/users’, async (req, res) => {
const users = await prisma.user.findMany() // Fetch all users
res.json(users) // Send the list of users as a JSON response
})

app.listen(3000, () => console.log(‘REST API server ready at: http://localhost:3000’))

Here’s what’s going on in the code:

• GET Request for /users: The route handler listens for GET requests at /users. Whenever a request is made to this endpoint, it fetches all users from the database using prisma.user.findMany().
• Responding with Data: The res.json(users) sends the list of users as a JSON response to the client. This makes it easy for the client to display the data.

Running the Server

After adding the route, save the file and close it. You can start your local web server by running the following command:

$ npx ts-node src/index.ts

Once the server is running, you should see this message in your terminal:

REST API server ready at: http://localhost:3000

Testing the /users Route

To test the /users route, open a new terminal window (make sure the server is still running), and use curl, a terminal-based HTTP client, to send a request to the server:

$ curl http://localhost:3000/users

You should get a response that contains the user data you created earlier. For example, it might look something like this:

[{“id”:1,”email”:”[email protected]”,”name”:”Alice”}]

This response shows the user with ID 1, email [email protected], and name Alice. Notice that the posts array isn’t included here because we didn’t pass the include option to the findMany query in the /users route.

Testing with GUI Tools

If you’re not into using the terminal and prefer something more visual, you can use GUI-based tools like Hoppscotch or Postman. These tools let you send HTTP requests and view the responses in a way that’s a bit friendlier than the command line.

Next Steps

Now that the /users route is up and running, you’ve got a basic API that can fetch user data. The next steps involve building out more functionality for your REST API, like adding routes to manage posts, update user data, and handle other CRUD operations.

To learn more about creating and implementing REST API routes effectively, explore this detailed resource on Implementing REST APIs in Node.js with Express.

Step 6 — Implementing the Remaining REST API Routes

In this step, you’ll be adding the rest of your REST API routes for your blogging app. By the end of it, your server will be ready to handle a variety of HTTP requests, like GET, POST, PUT, and DELETE. Here’s a rundown of the routes we’ll be adding:

• GET /feed: Fetches all published posts.
• GET /post/:id: Fetches a specific post by its ID.
• POST /user: Creates a new user.
• POST /post: Creates a new post (as a draft).
• PUT /post/publish/:id: Sets the “published” field of a post to true.
• DELETE /post/:id: Deletes a post by its ID.

Implementing the GET Routes

Let’s start by implementing the two GET routes. To get going, stop the server by pressing CTRL+C in your terminal. Then, open up your index.ts file for editing:

nano src/index.ts

Now, let’s add the following lines to define those two GET routes:

app.use(express.json())
app.get(‘/feed’, async (req, res) => {
const posts = await prisma.post.findMany({
where: { published: true }, // Fetch only published posts
include: { author: true }, // Include related author information
})
res.json(posts) // Send the list of published posts
})

app.get(‘/post/:id’, async (req, res) => {
const { id } = req.params
const post = await prisma.post.findUnique({
where: { id: Number(id) }, // Find a specific post by ID
})
res.json(post) // Send the found post
})

app.listen(3000, () => console.log(‘REST API server ready at: http://localhost:3000’))

Breakdown of the GET Routes

• /feed: This route retrieves all the posts that have been published. It uses Prisma Client’s findMany() method with a where condition to get only the posts where the published field is set to true. The include option is also used to get the related author information for each post.
• /post/:id: This route lets you fetch a specific post based on the ID you pass in the URL. It uses Prisma Client’s findUnique() method, and grabs the ID from the URL’s params. That allows the app to return a single post, based on the ID provided.

Testing the GET Routes

Once you’ve added the new routes, save and exit the file. Restart the server with:

npx ts-node src/index.ts

You should see this in the terminal:

REST API server ready at: http://localhost:3000

Testing the /feed Route

To test the /feed route, open a new terminal window (keeping your server running) and use curl to make a request to this endpoint:

curl http://localhost:3000/feed

Since no posts have been published yet, you’ll get an empty array:

[]

Testing the /post/:id Route

Next, let’s test the /post/:id route by making a request for a specific post ID:

curl http://localhost:3000/post/1

If there’s a post with ID 1, you should see something like this:

{
“id”: 1,
“title”: “Hello World”,
“content”: null,
“published”: false,
“authorId”: 1
}

Implementing the POST Routes

Now, we’re moving on to the POST routes for creating new users and posts. Again, stop the server by pressing CTRL+C and open up index.ts for editing:

nano src/index.ts

Add this code to implement the two POST routes:

app.post(‘/user’, async (req, res) => {
const result = await prisma.user.create({
data: { …req.body }, // Pass the request body data to the Prisma create method
})
res.json(result) // Send the created user data
})

app.post(‘/post’, async (req, res) => {
const { title, content, authorEmail } = req.body
const result = await prisma.post.create({
data: {
title,
content,
published: false, // Default value for new posts is false
author: { connect: { email: authorEmail } }, // Link the post to an existing user by email
},
})
res.json(result) // Send the created post data
})

app.listen(3000, () => console.log(‘REST API server ready at: http://localhost:3000’))

Explanation of the POST Routes

• /user: This route allows you to create a new user in the database. It uses Prisma Client’s create() method and passes the data from the request body (like name and email) directly into the query.
• /post: This route creates a new post. The request body should include the post’s title, content, and author’s email. The create() method is used, and the post’s author is linked to an existing user by email using the connect method.

Testing the POST Routes

To create a new user through the /user route, you can send a POST request using curl like this:

curl -X POST -H “Content-Type: application/json” -d ‘{“name”:”Bob”, “email”:”[email protected]”}’ http://localhost:3000/user

This will return something like:

{“id”:2,”email”:”[email protected]”,”name”:”Bob”}

To create a new post via the /post route, run this command:

curl -X POST -H “Content-Type: application/json” -d ‘{“title”:”I am Bob”, “authorEmail”:”[email protected]”}’ http://localhost:3000/post

The response will look like:

{“id”:2,”title”:”I am Bob”,”content”:null,”published”:false,”authorId”:2}

Implementing the PUT and DELETE Routes

Stop the server one more time, open index.ts again, and add the following routes for updating and deleting posts:

nano src/index.ts

Add this code:

app.put(‘/post/publish/:id’, async (req, res) => {
const { id } = req.params
const post = await prisma.post.update({
where: { id: Number(id) },
data: { published: true }, // Set the post’s published field to true
})
res.json(post) // Send the updated post
})

app.delete(‘/post/:id’, async (req, res) => {
const { id } = req.params
const post = await prisma.post.delete({
where: { id: Number(id) }, // Delete the post by its ID
})
res.json(post) // Send the deleted post’s data
})

app.listen(3000, () => console.log(‘REST API server ready at: http://localhost:3000’))

Explanation of the PUT and DELETE Routes

• /post/publish/:id (PUT): This route is used to publish a post by setting its published field to true. It grabs the post’s ID from the URL parameters and uses the update() method to modify the post’s status.
• /post/:id (DELETE): This route deletes a post by its ID using the delete() method.

Testing the PUT and DELETE Routes

To test the PUT route and publish a post, use this curl command:

curl -X PUT http://localhost:3000/post/publish/2

After publishing the post, you can test the DELETE route with:

curl -X DELETE http://localhost:3000/post/1

To make sure the post with ID 1 was deleted, send another GET request:

curl http://localhost:3000/post/1

Final Result

At this point, you’ve successfully added all the remaining REST API routes for your blogging app. Your API now supports GET, POST, PUT, and DE
