How to Build a Simple Web App Using GitHub Copilot in 2026

Building a web app can feel daunting, especially if you're a beginner. You might have the idea, but when it comes to coding, you might feel lost. Here’s where GitHub Copilot comes in. It’s like having a coding buddy who can help you write code quickly and efficiently, but it's important to know how to leverage it properly. In just about 2 hours, you can create a simple web app using GitHub Copilot, and I’m here to guide you through it step-by-step.

Prerequisites

Before you dive in, make sure you have the following:

• GitHub Account: You’ll need this to access GitHub Copilot.
• Visual Studio Code (VS Code): Download and install it if you don’t have it already.
• GitHub Copilot Subscription: It's $10/month after a free trial, which is pretty reasonable for what it offers.

Step-by-Step Guide

Step 1: Set Up Your Environment

1. Install Visual Studio Code: If you haven’t installed it yet, go to Visual Studio Code and download the latest version.
2. Install GitHub Copilot: Open VS Code, go to the Extensions view (Ctrl+Shift+X), and search for "GitHub Copilot". Click "Install".

Step 2: Create a New Project

1. Open VS Code.
2. Create a new folder for your project and open it in VS Code.
3. Create an index.html file for your web app.

Step 3: Start Coding with Copilot

Now the fun part begins! Here’s how to utilize GitHub Copilot effectively:

1. Write Comments: Start by writing a comment about what you want to achieve. For example:

   <!-- Create a simple webpage with a title and a button -->
   

   Copilot will suggest code based on your comment. Accept the suggestion to auto-generate the HTML structure.

2. Build Features Incrementally: Add features one at a time. For instance, if you want to create a button that alerts "Hello World", write:

   <!-- Create a button that alerts "Hello World" -->
   

   Copilot will likely suggest the JavaScript code you need.

3. Refine and Edit: Sometimes Copilot’s suggestions may not be perfect. Review the code it generates and make necessary adjustments.

Expected Outputs

After completing the above steps, you should have a simple web app that looks something like this:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>My Simple Web App</title>
</head>
<body>
    <h1>Welcome to My Web App</h1>
    <button onclick="alert('Hello World')">Click Me!</button>
    <script>
        // JavaScript code here
    </script>
</body>
</html>

Step 4: Troubleshooting Common Issues

• Copilot Doesn't Suggest Anything: Make sure your comments are clear. If it still doesn't work, try refreshing VS Code.
• Code Doesn’t Work: Double-check the syntax. Sometimes Copilot gets it wrong, especially with complex functions.

What's Next?

You now have a basic web app! Consider the following next steps:

• Styling: Add CSS to make your app look better.
• Deploy: Use platforms like GitHub Pages or Netlify to host your web app. Both are free for basic usage.
• Enhance Functionality: Explore adding more features, like a form or data fetching.

Conclusion

Building a simple web app using GitHub Copilot is not only feasible but also a fun way to learn how to code. Start with a clear idea, use comments to guide Copilot, and refine the code it suggests. With practice, you’ll get faster and more proficient.

What We Actually Use

In our experience, GitHub Copilot is a valuable tool for quickly generating code snippets, especially for beginners. However, it’s essential to know how to refine and edit the suggestions to suit your needs. If you find Copilot's suggestions lacking, consider supplementing your learning with resources like MDN Web Docs or Codecademy.
