How to Build Your First App with GitHub Copilot in 7 Days

If you're a beginner looking to build your first app, you might feel overwhelmed by the sheer amount of resources and tools available. Enter GitHub Copilot—a tool that can help you code faster and more intuitively. But can it really transform a newbie into a confident coder in just seven days? Let’s break down how you can leverage GitHub Copilot to build your first app, while keeping costs low and expectations realistic.

Prerequisites: What You Need Before Starting

Before diving in, here’s what you’ll need to get started:

• Basic programming knowledge: Familiarity with JavaScript or Python is helpful.
• GitHub Account: You can sign up for free.
• Visual Studio Code: Free code editor where you'll integrate Copilot.
• GitHub Copilot subscription: $10/month after a 30-day free trial.
• Time commitment: Approximately 1-2 hours daily over the week.

Day 1: Setting Up Your Environment

Step-by-Step Setup

1. Create a GitHub account if you don’t already have one.
2. Download and install Visual Studio Code.
3. Install the GitHub Copilot extension:
   • Open VS Code, go to Extensions, and search for GitHub Copilot.
   • Click "Install."
4. Sign in to GitHub within VS Code to activate Copilot.

Expected Output

By the end of Day 1, you should have a fully set up development environment and be ready to start coding.

Day 2: Brainstorming Your App Idea

Choosing the Right Project

Pick a simple app idea that you can realistically build in a week. Here are some suggestions:

• To-do list application
• Weather app using a public API
• Simple blog platform

Our Take

We recommend starting with a to-do list app. It covers basic CRUD (Create, Read, Update, Delete) operations, which are foundational for many applications.

Day 3: Structuring Your App

Planning Your App’s Features

Define the features you want to include, such as:

• User authentication
• Task creation
• Task deletion
• Task completion status

Using Copilot for Guidance

As you outline your features, use Copilot to generate code snippets. For example, type “create a function to add a task” and see what Copilot suggests.

Limitations

Keep in mind that Copilot may not always provide the best solution. You’ll still need to review and modify its suggestions.

Day 4: Building the Frontend

Step-by-Step Frontend Development

1. Set up HTML/CSS files for your app.
2. Use Copilot to generate basic HTML structure:
   • Start typing <div> and let Copilot fill in the rest.
3. Style your app using CSS, asking Copilot for help with specific styles.

Expected Output

You should have a basic layout for your app by the end of Day 4, ready for functionality to be added.

Day 5: Implementing the Backend

Building Your Backend

1. Choose a backend framework: Express for Node.js or Flask for Python are great choices.
2. Set up your server and routes using Copilot to generate boilerplate code.

Example Code Snippet

You might type “create an Express server” and let Copilot generate the initial setup.

Limitations

Copilot may not cover more complex logic well, so be prepared to refer to documentation.

Day 6: Connecting Frontend and Backend

Integrating Your App

1. Fetch data from your backend using JavaScript’s fetch API.
2. Use Copilot to help with AJAX requests by typing comments that describe what you need.

Expected Output

By the end of Day 6, your app should be fully functional, allowing users to add and delete tasks.

Day 7: Testing and Deployment

Final Steps

1. Test your app thoroughly to catch any bugs.
2. Deploy your app using platforms like Heroku or Vercel (both offer free tiers).

Troubleshooting Section

If you encounter issues, check the console for errors and consult Copilot for debugging suggestions.

Conclusion: Start Here

Building your first app with GitHub Copilot is not just possible; it can be a fun and educational experience. Start with a simple project, set aside daily time, and lean on Copilot as a coding partner.

What We Actually Use:

• GitHub for version control.
• Visual Studio Code with Copilot for coding assistance.
• Heroku for deployment.

By following this plan, you’ll be surprised at what you can accomplish in just seven days.
