How to Build a Complete Application Using GitHub Copilot in 30 Days

Building an application can feel like a daunting task, especially if you're navigating it solo or as a side project. The good news? With tools like GitHub Copilot, you can leverage AI to streamline your development process. In this guide, I’ll show you how to build a complete application using GitHub Copilot in just 30 days, sharing real experiences, practical steps, and the limitations of relying on AI.

Why Use GitHub Copilot?

GitHub Copilot is an AI-powered code completion tool that can help you write code faster and with fewer errors. It suggests whole lines or blocks of code based on the context of what you’re working on. However, it's not a magic solution; it requires your guidance and understanding of the project.

What You’ll Build

For this guide, we’ll create a simple task management application. By the end of 30 days, you’ll have a functional app that allows users to create, read, update, and delete tasks.

Prerequisites

• Time: You’ll need about 2-3 hours a week to dedicate to this project.
• Skills: Basic knowledge of JavaScript, HTML, and CSS.
• Tools:
  • GitHub Copilot (pricing: $10/month after trial)
  • GitHub account (free)
  • Node.js (free)
  • A code editor like VSCode (free)

Step-by-Step Breakdown

Day 1-3: Set Up Your Environment

1. Install Node.js: Download and install from the official site.
2. Set Up GitHub: Create a new repository for your project.
3. Enable GitHub Copilot: Activate it in your VSCode settings.

Day 4-10: Build the Basic Structure

1. Create Your Project Structure:

   • Use Copilot to generate basic folder structures (e.g., /src, /public, /styles).
   • Expected output: A clean project layout.

2. Initialize Your App:

   • Use Copilot to set up a basic Express server.
   • Expected output: A server running on localhost.

Day 11-15: Implement Core Features

1. Task Creation:

   • Ask Copilot to generate a function for adding tasks.
   • Limitations: Be prepared to modify the suggested code to fit your specific needs.

2. Task Display:

   • Use Copilot to create a function to retrieve and display tasks.
   • Expected output: A list of tasks displayed in the browser.

Day 16-20: Add Update and Delete Functionality

1. Update Tasks:

   • Implement functionality to edit tasks using Copilot's suggestions.
   • Expect some trial and error; Copilot may not always get the logic right.

2. Delete Tasks:

   • Add a delete function and ensure it interacts correctly with your database.
   • Test thoroughly to avoid any data loss.

Day 21-25: Styling and User Interface

1. Use CSS Frameworks:

   • Implement a CSS framework like Bootstrap or Tailwind CSS.
   • Copilot can help generate responsive design components.

2. User Testing:

   • Share the app with friends or colleagues for feedback.
   • Iterate based on their suggestions.

Day 26-30: Final Touches and Deployment

1. Deploy Your App:

   • Use services like Heroku or Vercel to deploy your application.
   • Copilot can assist with setting up the deployment scripts.

2. Documentation:

   • Write clear documentation for your app. Use Copilot to help generate README files.

Potential Challenges

• Learning Curve: While Copilot is powerful, it’s not perfect. You will need to understand the code it generates.
• Debugging: Be prepared to troubleshoot issues that arise from AI-generated code.
• Cost: GitHub Copilot is priced at $10/month, which can add up if you’re on a tight budget.

What We Actually Use

In our team, we rely on GitHub Copilot for rapid prototyping but also combine it with manual coding to ensure quality. We find it particularly useful for generating boilerplate code and repetitive tasks.

Conclusion

Building an application using GitHub Copilot in 30 days is entirely feasible. Start with a clear plan, utilize the power of AI for repetitive tasks, and don’t shy away from getting your hands dirty with code.

Start here: begin your journey by setting up your environment and enabling GitHub Copilot. With consistent effort and the right mindset, you’ll have a fully functional application in no time.
