If you're a solo founder or an indie hacker, you probably know that writing code can be a time-consuming and sometimes frustrating task. Enter GitHub Copilot, an AI-powered coding assistant that can help you crank out code faster than ever. In this guide, I'll show you how to leverage GitHub Copilot to write 100 lines of code in just 30 minutes. Yes, you read that right. Let's dive in.

Prerequisites: What You Need Before Starting

Before you jump into using GitHub Copilot, make sure you have the following:

• GitHub Account: Sign up for free if you don’t have one.
• Visual Studio Code (VS Code): Download and install this code editor if you haven't already. It's free and widely used.
• GitHub Copilot Subscription: As of March 2026, GitHub Copilot costs $10/month after a 30-day free trial.

Step-by-Step Guide to Writing 100 Lines of Code

Step 1: Set Up Your Environment (5 minutes)

1. Install Visual Studio Code: Go to the VS Code website and download the appropriate version for your OS.
2. Install GitHub Copilot: Open VS Code, navigate to the Extensions view, and search for "GitHub Copilot." Click "Install."

Step 2: Create a New Project (5 minutes)

1. Open VS Code and create a new folder for your project.
2. Create a new file named app.js (or any language you prefer) within that folder.

Step 3: Write a Simple Function (10 minutes)

1. Start with a comment: Type // Function to calculate factorial and press Enter. Copilot will suggest code for you.
2. Accept the suggestion: If it looks good, hit Tab to accept it.
3. Add more comments to guide Copilot for additional functions, such as // Function to calculate Fibonacci series, and accept its suggestions.

Step 4: Iterate and Expand (5 minutes)

1. Use Copilot’s suggestions to flesh out your functions. You can type partial lines or comments, and it will try to complete them.
2. Refine the code by testing it in the terminal. Remember to run your code frequently to catch errors early.

Step 5: Review and Finalize (5 minutes)

1. Go through the code and make any necessary tweaks.
2. Add comments to explain your logic, which can also guide future Copilot suggestions.

Expected Output

After following these steps, you should have a functional script with at least 100 lines of code, including comments and functions.

Troubleshooting: What Could Go Wrong

• Copilot Suggests Incorrect Code: If the suggestions are off, try rephrasing your comments or adding more context.
• Performance Issues: If VS Code is slow, check your system resources or consider closing other applications.

What's Next: Building on Your Code

Once you've successfully written your code, consider the following next steps:

• Integrate with a Database: Use tools like Firebase or MongoDB to store your data.
• Deploy Your Application: Explore platforms like Heroku or Vercel for easy deployment.
• Iterate and Improve: Use feedback from users to refine your code and add features.
