How to Use GitHub Copilot to Generate Code in 30 Minutes

If you're a solo founder or indie hacker, you know that time is often your most valuable resource. Enter GitHub Copilot, an AI-powered coding assistant that can help you generate code snippets faster than you can type them. In this guide, I’ll show you how to get started with GitHub Copilot in just 30 minutes, so you can spend less time coding and more time building your project.

Prerequisites: What You Need Before Starting

Before diving in, here’s what you need:

• A GitHub account (Free or Pro)
• Visual Studio Code (VS Code) installed on your computer
• GitHub Copilot subscription ($10/month or $100/year for individuals)
• Basic understanding of JavaScript or Python (or the language you plan to use)

Step 1: Setting Up GitHub Copilot

1. Install VS Code: If you don't have VS Code yet, download and install it from here.

2. Sign Up for GitHub Copilot: Go to the GitHub Copilot page and sign up. Choose the monthly or yearly subscription based on your needs.

3. Install the GitHub Copilot Extension: Open VS Code, go to the Extensions tab (or press Ctrl+Shift+X), and search for "GitHub Copilot". Click "Install".

4. Sign In: Once installed, sign in with your GitHub account. You may need to authorize the extension to access your GitHub account.

Expected Output: You should see a prompt in your VS Code editor indicating that GitHub Copilot is ready to assist you.

Step 2: Generating Code with Copilot

1. Create a New File: Start a new file in VS Code with the appropriate file extension (e.g., .js for JavaScript or .py for Python).

2. Write a Comment: Begin by writing a comment that describes what you want to achieve. For example:

   // Function to calculate the factorial of a number
   

3. Let Copilot Suggest: Hit Enter and wait for GitHub Copilot to generate a code suggestion. It might suggest a complete function based on your comment.

4. Accept the Suggestion: If you like the suggestion, press Tab to accept it. You can also cycle through other suggestions by pressing Ctrl + ] or Ctrl + [.

Expected Output: You should see a complete function generated by Copilot that you can further customize.

Step 3: Fine-Tuning Your Code

1. Modify the Code: After accepting a suggestion, you might want to tweak variables or add error handling. Copilot can also help with these modifications. Just type your intention, and it will suggest relevant changes.

2. Test Your Code: Run the code in your terminal or use any testing framework you're comfortable with to ensure it works as expected.

Expected Output: A working function that meets your requirements.

Troubleshooting Common Issues

• No Suggestions Appearing: If Copilot isn’t suggesting code, ensure you’re connected to the internet and that the extension is enabled in VS Code.

• Irrelevant Suggestions: Sometimes, Copilot might not understand your comment. Try rewriting it for clarity.

• Performance Issues: If VS Code feels slow, consider disabling other unused extensions.

What's Next?

Once you’ve generated some code with Copilot, you can explore more advanced features such as:

• Integrating Copilot with other languages.
• Using it alongside frameworks like React or Django.
• Exploring Copilot Labs for more experimental features.

Conclusion: Start Here with GitHub Copilot

In our experience, GitHub Copilot is a valuable tool for speeding up the coding process, especially for repetitive tasks or boilerplate code. While it’s not perfect and can miss context at times, the time savings are undeniable. Start by setting up your environment and generating simple functions, then gradually incorporate it into your workflow.

What We Actually Use

For our projects, we primarily use GitHub Copilot for generating boilerplate code and quick functions. We find it particularly useful when prototyping new features or when we're stuck on syntax. However, we still review the generated code carefully, as it’s not always perfect.
