How to Build a Simple App with GitHub Copilot in 2 Hours
How to Build a Simple App with GitHub Copilot in 2026
Building an app can feel like a daunting task, especially if you’re a beginner. You might be asking yourself if you have the right skills or how long it’s going to take. Well, here's the good news: with GitHub Copilot, you can build a simple app in about 2 hours. Yes, I said 2 hours. In this guide, I’ll walk you through the process, share the tools you’ll need, and provide some honest insights based on our experience.
Prerequisites: What You Need Before You Start
Before diving in, make sure you have the following:
- GitHub Account: You’ll need this for Copilot and version control.
- Visual Studio Code: This is the IDE we'll be using, and GitHub Copilot integrates seamlessly with it.
- Node.js and npm: Install these to manage your app dependencies.
- Basic JavaScript Knowledge: You don’t need to be an expert, but some familiarity will help.
Step-by-Step Guide to Building Your App
Step 1: Set Up Your Environment (15 minutes)
- Install Visual Studio Code: Download and install it from here.
- Install GitHub Copilot: You can get a subscription for $10/month after a free trial.
- Install Node.js: Download it from here. This also installs npm.
- Create a New Project: Open VS Code, and create a new folder for your app. Open the terminal and run:
mkdir my-simple-app cd my-simple-app npm init -y
Step 2: Create Your App (1 hour)
-
Set Up Your Basic Files: Create an
index.jsfile and anindex.htmlfile in your project folder. -
Write Your HTML: In
index.html, create a basic HTML structure.<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <meta name="viewport" content="width=device-width, initial-scale=1.0"> <title>My Simple App</title> </head> <body> <h1>Hello, World!</h1> <script src="index.js"></script> </body> </html> -
Use GitHub Copilot to Generate Code: In
index.js, start typing a function, and Copilot will suggest code. For example, type:function greet() { console.log('Hello from GitHub Copilot!'); }Then accept the suggestion or modify it as needed.
-
Run Your App: Use a live server extension in VS Code (like Live Server) to view your app in the browser.
Step 3: Testing and Debugging (30 minutes)
- Test Your App: Make sure everything works as expected. Use the browser console to check for errors.
- Troubleshooting: If something doesn't work, check:
- Console errors in the browser.
- Typos in your code.
- Make sure all files are linked correctly.
What Could Go Wrong
- Copilot Suggestions May Not Fit: Sometimes, the code suggestions might not be what you want. Don’t hesitate to tweak them.
- Dependency Issues: If you run into issues with npm packages, check the package documentation for compatibility.
What's Next
Once you've built the app, consider expanding its functionality. You could add features like user input, API calls, or even a simple database connection. This is where you can really start to learn and grow as a developer.

What We Actually Use
We primarily rely on GitHub Copilot for code suggestions, Visual Studio Code for development, and Postman for API testing. This stack keeps our workflow efficient and allows us to focus on building rather than troubleshooting.
