How to Build a Simple App Using GitHub Copilot in 45 Minutes

Let’s be real: building an app can feel daunting, especially if you’re a solo founder or indie hacker who’s not a coding wizard. But what if I told you that you could leverage AI to turbocharge your development process? With GitHub Copilot, you can build a simple app in just 45 minutes. Sounds too good to be true? Let’s dive in.

Prerequisites: What You Need Before You Start

Before we jump into the app-building process, there are a few things you’ll need:

1. GitHub Account: Sign up for free if you don’t have one.
2. Visual Studio Code (VS Code): Download and install VS Code, which is a free code editor.
3. GitHub Copilot: You’ll need a subscription, which costs $10/month after a 60-day free trial.
4. Basic Understanding of JavaScript: Familiarity with coding concepts will help, but I’ll guide you through the basics.

Step 1: Set Up Your Environment (10 Minutes)

1. Install GitHub Copilot:

   • Open VS Code.
   • Go to Extensions (Ctrl+Shift+X).
   • Search for “GitHub Copilot” and click install.

2. Create a New Project:

   • Open a new terminal in VS Code (Ctrl+`).
   • Run mkdir my-simple-app to create a new directory and cd my-simple-app to enter it.
   • Initialize a new Node.js project by running npm init -y.

3. Install Express:

   • Run npm install express to set up a simple server.

Step 2: Start Coding with GitHub Copilot (25 Minutes)

Now comes the fun part. You’ll use GitHub Copilot to write code. Here’s how:

1. Create the Server File:

   • In your project folder, create a file called server.js.
   • Start typing const express = require('express'); and watch Copilot suggest the rest of the server setup. Hit Tab to accept suggestions.

2. Set Up Routes:

   • Type app.get('/', (req, res) => { and see Copilot suggest a simple response. Accept it to create your homepage.

3. Run Your Server:

   • Add app.listen(3000, () => console.log('Server running on http://localhost:3000')); to start the server.
   • Save the file and run node server.js in the terminal.

4. Test Your App:

   • Open your browser and go to http://localhost:3000. You should see your response!

Step 3: Troubleshooting Common Issues

While the process is straightforward, you might run into a few hiccups:

• Copilot Doesn’t Suggest Code: Make sure you’re connected to the internet and GitHub Copilot is enabled in VS Code.
• Server Not Starting: Double-check that you’ve installed Express correctly. If you see errors, read the console output for hints on what’s wrong.

What's Next: Enhancing Your App

Now that you have a basic app running, here are some ideas for enhancements:

• Add More Routes: Create additional pages for different functionalities.
• Integrate a Database: Use MongoDB or SQLite for data storage.
• Deploy Your App: Consider using platforms like Heroku or Vercel for deployment, which have free tiers.

Conclusion: Start Here

Building an app doesn’t have to be a long, drawn-out process. With GitHub Copilot, you can create a simple app in just 45 minutes. Start by following this guide, and don’t hesitate to iterate on your project. The more you play with it, the more comfortable you’ll become.

What We Actually Use

In our experience, GitHub Copilot is a powerful tool for speeding up development, but it’s not perfect. We often pair it with Stack Overflow for troubleshooting and specific coding challenges.
