How to Build a Simple Web App Using GitHub Copilot in Just 2 Hours
If you've ever felt overwhelmed at the thought of building a web app from scratch, you're not alone. Many indie hackers and solo founders struggle with coding, especially if they don't have a background in software development. But what if I told you that you could leverage AI to accelerate your coding process significantly? In this guide, we'll walk through building a simple web app using GitHub Copilot in just 2 hours. Yes, you read that right!
Prerequisites: What You Need Before You Start
Before diving into the development process, make sure you have the following:
- GitHub Account: You’ll need a GitHub account to use Copilot. Sign up for free if you don’t have one.
- Visual Studio Code (VS Code): Download and install VS Code, which is where we’ll be writing our code.
- GitHub Copilot Subscription: Copilot costs $10/month or $100/year. There’s a free trial available, so you can test it out.
- Basic HTML/CSS/JavaScript Knowledge: Familiarity with these languages will help you understand what you're building.
Step 1: Setting Up Your Environment
Time: 15 minutes
- Install Visual Studio Code: Go to the VS Code website and download the latest version for your OS.
- Install GitHub Copilot: Open VS Code, go to Extensions (Ctrl+Shift+X), and search for "GitHub Copilot." Click Install.
- Create a New Project Folder: Name it something like "MyWebApp".
Step 2: Initialize Your Project
Time: 10 minutes
- Open your project folder in VS Code.
- Create your main files: Inside your project folder, create
index.html,style.css, andapp.js.
Expected output: Your project structure should look like this:
MyWebApp/
├── index.html
├── style.css
└── app.js
Step 3: Using GitHub Copilot to Write Code
Time: 1 hour
- Open
index.htmland start typing: Begin with a basic HTML structure. As you type, GitHub Copilot will suggest completions.- For example, type
<!DOCTYPE html>and see what suggestions come up.
- For example, type
- Add a basic layout: Use Copilot to create a header and a simple form. You can type comments like
<!-- Create a header -->and let Copilot generate the HTML for you. - Style with CSS: Open
style.cssand type in some basic styles. Copilot can help you with common CSS properties. - Implement functionality in
app.js: Add simple JavaScript functions. For example, if you typefunction submitForm(), Copilot will suggest a complete function based on your input.
Example Code Snippet
<!-- index.html -->
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="style.css">
<title>My Web App</title>
</head>
<body>
<header>
<h1>Welcome to My Web App</h1>
</header>
<form onsubmit="submitForm(); return false;">
<input type="text" placeholder="Enter something..." required>
<button type="submit">Submit</button>
</form>
<script src="app.js"></script>
</body>
</html>
Step 4: Testing Your Web App
Time: 20 minutes
- Open your
index.htmlin a browser: Right-click on the file in VS Code and select "Open with Live Server" (you may need to install the Live Server extension). - Test functionality: Ensure that your form submits correctly and any JavaScript functionality works as expected.
Troubleshooting: What Could Go Wrong
- Copilot is not suggesting anything: Ensure you're logged into GitHub in VS Code.
- Errors in JavaScript: Use the console in your browser's developer tools to debug any issues.
What’s Next: Expanding Your Web App
Once you've built your basic web app, consider adding more features like user authentication, database integration, or deploying your app to a platform like Vercel or Netlify.
Conclusion: Start Here
Building a web app doesn't have to be daunting. With GitHub Copilot, you can significantly speed up your development process. Start with the basics, leverage AI to write your code, and don't forget to iterate on your project as you learn!
What We Actually Use
We rely on GitHub Copilot for rapid prototyping and coding assistance. However, we also recommend checking out alternatives like Tabnine or Codeium if you're looking for different AI coding experiences.
