How to Use GitHub Copilot to Write 100 Lines of Code in 30 Minutes

If you’re a solo founder or an indie hacker, you know that time is often your most precious resource. Writing code can be a time-consuming task, especially when you’re juggling multiple projects. Enter GitHub Copilot: an AI-powered coding assistant designed to help you write code faster. In this guide, I’ll show you how to leverage Copilot to crank out 100 lines of code in just 30 minutes.

Prerequisites: What You Need

Before diving into the coding session, here are a few things you’ll need:

• A GitHub account (free).
• Visual Studio Code installed on your machine.
• GitHub Copilot extension installed in Visual Studio Code (free trial available; $10/month thereafter).
• Basic understanding of the programming language you plan to use (JavaScript, Python, etc.).

Step 1: Set Up Your Environment (5 Minutes)

1. Install Visual Studio Code: If you haven’t already, download and install Visual Studio Code from here.
2. Install GitHub Copilot: Go to the Extensions Marketplace in VS Code, search for “GitHub Copilot,” and install it. You’ll need to log into your GitHub account and authorize the extension.
3. Create a New Project: Open a new folder in VS Code and create a new file (e.g., app.js or script.py).

Step 2: Define Your Project Scope (5 Minutes)

Before you start coding, it's crucial to know what you want to accomplish. For this example, let’s say we’re building a simple web application feature—like a to-do list. Outline the primary functions you need:

• Add a task.
• Mark a task as complete.
• Delete a task.
• List all tasks.

Step 3: Use GitHub Copilot to Generate Code (15 Minutes)

Now comes the fun part. Here’s how to effectively use Copilot to generate code based on your outlined features:

1. Start with Comments: Write a comment describing what you want to do. For example:

   // Function to add a task
   

   Copilot will suggest code for you based on this comment. Accept the suggestions by pressing Tab.

2. Iterate for Each Function: Repeat this process for each function:

   // Function to mark a task as complete
   // Function to delete a task
   // Function to list all tasks
   

3. Review and Edit: After generating the code, review it. Make any necessary tweaks to fit your specific requirements. This is where you refine the AI-generated code.

Step 4: Test Your Code (5 Minutes)

Once you have your 100 lines of code (or close to it), run your application to see if everything works as expected. You can do this in your terminal or through a browser if it’s a web app.

Expected Outputs:

You should see:

• A working interface for adding, completing, and deleting tasks.
• No syntax errors or crashes.

Troubleshooting: What Could Go Wrong

1. Syntax Errors: If Copilot generates code that doesn’t compile, look for mismatched parentheses or incorrect variable names.
2. Logic Errors: If the functionality isn’t working as expected, check the logic in the generated code. Sometimes, you might need to adjust how functions interact.

What’s Next

Once you’ve built your feature, consider expanding it. You might want to add user authentication, persistence (using a database), or even deploy it using a service like Vercel or Netlify.

Conclusion: Start Here

If you’re new to coding or just want to speed up your development process, GitHub Copilot is a powerful tool worth trying. Set aside 30 minutes, follow the steps outlined above, and you’ll be amazed at how much you can accomplish.

Pricing Breakdown for GitHub Copilot

| Feature | Pricing | Best For | Limitations | Our Take | |-----------------------|----------------------|-------------------------------|-----------------------------------------------|---------------------------------| | GitHub Copilot | Free trial, then $10/mo | Beginners to intermediates | Limited to specific languages and contexts | We use Copilot for rapid prototyping. |

What We Actually Use

In our experience, GitHub Copilot is best for generating boilerplate code quickly, but we still rely on manual coding for critical components to ensure quality. If you find Copilot isn’t working for you, consider alternatives like Tabnine or Codeium.
