How to Build a Simple App Using GitHub Copilot in Just 2 Hours

Building an app can feel overwhelming, especially if you're a solo founder or indie hacker without deep coding experience. But what if I told you that you could leverage AI to help you create a simple app in just 2 hours? Enter GitHub Copilot, the AI-powered coding assistant that can help you write code faster and more efficiently. In this tutorial, I’ll walk you through how to use GitHub Copilot to build a basic app, along with tips, tools, and a few pitfalls to avoid.

Time Estimate: 2 Hours

You can finish this project in about 2 hours, assuming you have a basic understanding of coding concepts and access to the necessary tools.

Prerequisites

1. GitHub Account: You'll need this to use GitHub Copilot and host your code.
2. Visual Studio Code: Download and install this code editor.
3. GitHub Copilot Subscription: As of March 2026, it costs $10/month after a 60-day free trial.
4. Node.js: Install this for running JavaScript applications.

Step-by-Step Guide to Building Your App

Step 1: Set Up Your Environment

1. Install Visual Studio Code: Download it from Visual Studio Code's website.
2. Install GitHub Copilot: Go to the Extensions Marketplace in VS Code and search for GitHub Copilot. Follow the prompts to install it.
3. Set Up Node.js: Download Node.js from nodejs.org and install.

Step 2: Create a New Project

1. Open Visual Studio Code and create a new folder for your project.
2. Open the terminal in VS Code and run:

   npm init -y
   

   This will create a package.json file for your app.

Step 3: Write Your First Code with Copilot

1. In your project folder, create a new file called app.js.
2. Start typing a comment like // Create a simple web server and wait for Copilot to suggest code.
3. Accept the suggestion by pressing Tab.

Step 4: Implement Features

1. Add more functionality by typing comments for each feature you want. For example:

   • // Add a route for home page
   • // Fetch data from an API

   Copilot will suggest code snippets based on these comments.

Step 5: Test Your App

1. In the terminal, run your app using:

   node app.js
   

2. Open your browser and go to http://localhost:3000 (or whichever port your app is set to).

Step 6: Debugging

If you encounter errors, here are common issues and solutions:

• Error: Port Already in Use: Change the port number in your code.
• Syntax Errors: Double-check the suggested code from Copilot. Sometimes it might not be perfect.

What's Next?

Once your app is running, think about:

• Adding a database for data persistence (e.g., MongoDB).
• Deploying your app using platforms like Heroku or Vercel.
• Enhancing the UI with frameworks like React or Vue.js.
