How to Set Up GitHub Copilot for JavaScript in 20 Minutes

If you’re a solo founder or indie hacker, you know the struggle of balancing coding with all the other hats you wear. Enter GitHub Copilot—an AI-powered coding assistant that promises to help you write code faster and more efficiently. But how do you actually set it up for JavaScript? Spoiler: it’s easier than you think. In this guide, I’ll walk you through the setup process in about 20 minutes.

Prerequisites

Before diving in, make sure you have the following:

1. GitHub Account: You’ll need an account to access GitHub Copilot.
2. Visual Studio Code (VS Code): This is where you’ll be coding. If you haven’t installed it yet, you can grab it here.
3. GitHub Copilot Subscription: As of January 2026, GitHub Copilot costs $10/month after a free trial.

Step 1: Install Visual Studio Code

If you don’t have VS Code installed already, head over to the VS Code download page. It’s free and lightweight, perfect for indie developers.

Step 2: Install GitHub Copilot Extension

1. Open VS Code.
2. Go to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side of the window.
3. Search for "GitHub Copilot".
4. Click "Install".

Step 3: Sign in to GitHub

1. After installing the extension, you’ll see a prompt to sign in to GitHub.
2. Click on the "Sign in" button and follow the authentication steps.
3. Grant permissions when prompted.

Step 4: Configure Settings

1. Open the Command Palette by pressing Ctrl + Shift + P.

2. Type "Preferences: Open Settings (JSON)" and hit enter.

3. Add or modify the following settings:

   "github.copilot.enable": true,
   "github.copilot.suggestAutomatically": true
   

This ensures that Copilot is enabled and will suggest code automatically.

Step 5: Start Coding

1. Create a new JavaScript file (.js).
2. Begin typing a function or a comment about what you want to do. For example, type // function to add two numbers.
3. Copilot will start suggesting code. Accept the suggestions by pressing Tab.

Expected Output

You should see GitHub Copilot generating code snippets based on your input. For example, it might generate an add function automatically when you type your comment.

Troubleshooting

• No Suggestions Appearing: Make sure you’re connected to the internet and that you’ve signed in correctly. Check the output panel for any error messages.
• Performance Issues: If VS Code is slow, try disabling other extensions to see if there’s a conflict.

What’s Next?

Once you’ve got Copilot up and running, consider exploring how it can assist with more complex JavaScript tasks, like setting up frameworks like React or Node.js. Also, check out our episodes on the Built This Week podcast for tips on maximizing AI tools in your workflow.

Pricing Breakdown

| Feature | Price | Best For | Limitations | Our Take | |-----------------------------|------------------|---------------------------------|--------------------------------|----------------------------------| | GitHub Copilot | $10/mo | Solo developers and startups | Limited to supported languages | We use it for faster prototyping. | | Free alternatives (e.g., TabNine) | Free (limited) | Beginners | Less accurate than Copilot | We don’t use it because it lacks features. |

Conclusion

Setting up GitHub Copilot for JavaScript is straightforward and can significantly boost your coding efficiency. Start by installing VS Code and the Copilot extension, then follow the steps to get coding with AI assistance in no time.

If you’re serious about speeding up your development process, give GitHub Copilot a try. You’ll find that it not only saves time but also helps you think through problems differently.
