How to Create a Simple Application Using GitHub Copilot in 2 Hours

In 2026, the landscape of coding has changed dramatically with the advent of AI tools like GitHub Copilot. If you've ever felt overwhelmed by the thought of building an application from scratch, you're not alone. Many indie hackers and solo founders struggle with the coding aspect of their projects. The good news? With GitHub Copilot, you can create a simple application in just two hours. Yes, you read that right! Let’s dive into how you can leverage this tool effectively.

Prerequisites: What You Need Before You Start

Before we jump into the actual coding, make sure you have the following:

• GitHub Account: Free account is sufficient.
• Visual Studio Code (VS Code): Download and install it from the official site. It’s free and works great with Copilot.
• GitHub Copilot Subscription: Costs $10/month or $100/year after a free trial. It’s essential for accessing the AI features.
• Basic Knowledge of JavaScript: Familiarity with JavaScript will help you understand the code that Copilot suggests.

Step 1: Setting Up Your Environment

1. Install VS Code: Once installed, open the editor.
2. Install GitHub Copilot: Go to the Extensions marketplace in VS Code and search for GitHub Copilot. Click on "Install" and log in with your GitHub account.
3. Create a New Project Folder: Name it something like "MyFirstApp".

Expected Output:

You should see a clean workspace in VS Code ready for coding.

Step 2: Start Coding with Copilot

Now, let’s create a simple to-do list application. Follow these steps:

1. Create an index.html File: This will be your main HTML file.
   • Type <!DOCTYPE html> and hit enter. Copilot will suggest the rest of the HTML structure.
2. Add Basic Structure: Start writing the <head> section. Copilot will assist you in filling in the title and linking stylesheets.
3. Create a script.js File: This file will handle the logic of your application.
   • Start by typing function addTask() and let Copilot fill in the function body.

Expected Output:

You should have a basic HTML structure and a JavaScript function ready to go.

Step 3: Building Features

1. Adding Tasks: Type out the functionality for adding a task. For example:

   function addTask(task) {
       // Code to add task
   }
   

   Let Copilot suggest the implementation.

2. Displaying Tasks: Type function displayTasks() and see what Copilot generates.

3. Styling with CSS: Create a styles.css file and start typing some styles. Copilot can suggest common styles based on class names.

Expected Output:

You should have a functional to-do list where you can add and display tasks.

Troubleshooting: What Could Go Wrong

• Copilot Doesn't Suggest What You Expect: If Copilot seems off, try rephrasing your function names or comments. It learns from context.
• Errors in Code: Always run your code in the browser to catch any errors. Debugging is part of the process!

What's Next: Expanding Your Application

Once you’ve got the basic app running, consider these enhancements:

• Add Local Storage: Save tasks even after refreshing the page.
• Implement Task Deletion: Allow users to remove tasks.
• Style It Up: Use a CSS framework like Bootstrap for better aesthetics.

Conclusion: Start Here

Creating an application with GitHub Copilot can be an efficient way to bring your ideas to life. With just two hours and some basic coding knowledge, you can have a simple yet functional app. Remember, the key is to dive in and let Copilot assist you along the way. If you get stuck, don’t hesitate to refer back to the documentation or seek help from the community.

What We Actually Use: We currently rely on GitHub Copilot for rapid prototyping and development. It saves us time and helps us focus on higher-level design decisions rather than getting bogged down by syntax errors.
