How to Use GitHub Copilot to Write Your First Application in Under 2 Hours

If you're like many indie hackers or solo founders, the thought of coding your first application can be daunting. But what if I told you that with the right tools, you could build something functional in under two hours? Enter GitHub Copilot, an AI-powered coding assistant that can streamline your development process. As of 2026, it's become a game-changing tool for beginners and experienced developers alike. Let’s dive into how you can leverage Copilot to get your first app off the ground quickly.

Prerequisites: What You Need to Get Started

Before we jump into the coding, here’s what you need to have ready:

1. GitHub Account: Sign up for free if you don’t already have one.
2. Visual Studio Code: Download and install this code editor; it’s the most compatible with Copilot.
3. GitHub Copilot Subscription: You'll need to subscribe to Copilot for $10/month after a 30-day free trial.
4. Basic Understanding of JavaScript: Familiarity with JavaScript will help, but Copilot can guide you through the syntax.

Setting Up GitHub Copilot

1. Install Visual Studio Code: If you haven't already, go to the Visual Studio Code website and download the app for your operating system.
2. Install GitHub Copilot Extension: Open Visual Studio Code, go to the Extensions view (Ctrl+Shift+X), and search for "GitHub Copilot." Click "Install."
3. Log In to GitHub: Once installed, you'll be prompted to sign in to your GitHub account. Follow the prompts to authorize Copilot.

Building Your First Application

Step 1: Set Up Your Project

1. Create a New Directory: Open your terminal and create a new folder for your project:

   mkdir my-first-app
   cd my-first-app
   

2. Initialize a Git Repository:

   git init
   

3. Create Your Initial Files: Start with an index.html and app.js:

   touch index.html app.js
   

Step 2: Use Copilot to Generate Code

1. Open index.html: Start by typing the basic HTML structure. Copilot will suggest completions as you type.

   <!DOCTYPE html>
   <html>
   <head>
       <title>My First App</title>
   </head>
   <body>
       <h1>Hello, World!</h1>
       <script src="app.js"></script>
   </body>
   </html>
   

   Copilot will fill in the rest based on your patterns.

2. Open app.js: Now, let’s add some interactivity. Type:

   function greet() {
       alert("Welcome to my first app!");
   }
   

   As you type, Copilot will suggest ways to enhance this function.

3. Add Event Listeners: Type a comment for Copilot:

   // Add event listener to greet on page load
   

   Copilot will likely suggest:

   window.onload = greet;
   

Step 3: Run Your Application

1. Open index.html in a Browser: You can simply double-click the file or use an extension like Live Server in Visual Studio Code for live reloading.
2. Test the Functionality: When the page loads, you should see an alert welcoming you to your app.

Troubleshooting Common Issues

• Copilot Doesn't Suggest Anything: Make sure you're logged in and the extension is enabled. Sometimes, restarting Visual Studio Code can help.
• Errors in Code: If you encounter errors, check your syntax. Copilot can make mistakes, so always review its suggestions.

What's Next?

Once you’ve built your first application, consider expanding its functionality. Here are a few ideas:

• Add a CSS File: Style your app with custom styles.
• Integrate APIs: Use a public API to fetch and display data.
• Deploy Your App: Explore platforms like Netlify or Vercel for easy deployment.

Conclusion: Start Here

GitHub Copilot is a powerful tool that can significantly reduce the time it takes to build your first application. With just a few hours and some basic coding knowledge, you can have a functional app ready to go. Remember, the key is to experiment and learn from the suggestions Copilot provides.

If you’re ready to dive in, start by setting up your environment as outlined above, and let Copilot guide you through the coding process. Happy building!
