How to Create a Simple To-Do App Using GitHub Copilot in 2 Hours

Building a simple to-do app is a classic project for developers, especially if you're just getting started. But what if I told you that you could leverage AI to speed up the process significantly? In this guide, I'm going to show you how to create a simple to-do app using GitHub Copilot in just 2 hours. Whether you're a beginner or looking to enhance your coding skills, this tutorial is designed to be practical and straightforward. Let's dive in!

Time Estimate

You can finish this in 2 hours if you follow the steps closely and have a basic understanding of JavaScript and GitHub.

Prerequisites

Before you start, make sure you have the following:

• A GitHub account (free)
• Visual Studio Code installed (free)
• The GitHub Copilot extension for Visual Studio Code (free for students or $10/mo for individual use)
• Basic knowledge of HTML, CSS, and JavaScript

Step-by-Step Guide

Step 1: Set Up Your Project

1. Create a New Repository on GitHub named simple-todo-app.
2. Clone the Repository to your local machine.
3. Open Visual Studio Code and navigate to your project folder.

Step 2: Create the Basic HTML Structure

In your project folder, create a file named index.html and add the following code:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>Simple To-Do App</title>
    <link rel="stylesheet" href="styles.css">
</head>
<body>
    <div id="app">
        <h1>My To-Do List</h1>
        <input type="text" id="taskInput" placeholder="Add a new task">
        <button id="addTaskButton">Add Task</button>
        <ul id="taskList"></ul>
    </div>
    <script src="script.js"></script>
</body>
</html>

Step 3: Style Your App

Create a file named styles.css and add some basic styles:

body {
    font-family: Arial, sans-serif;
    margin: 0;
    padding: 20px;
}

#app {
    max-width: 400px;
    margin: auto;
}

button {
    margin-left: 10px;
}

Step 4: Implement JavaScript Functionality

Create a file named script.js. Here, you can use GitHub Copilot to help you write the functionality. Start typing the following code and let Copilot suggest the rest:

const taskInput = document.getElementById('taskInput');
const addTaskButton = document.getElementById('addTaskButton');
const taskList = document.getElementById('taskList');

addTaskButton.addEventListener('click', function() {
    const task = taskInput.value;
    
    if (task) {
        const listItem = document.createElement('li');
        listItem.textContent = task;
        taskList.appendChild(listItem);
        taskInput.value = '';
    }
});

Expected Outputs

After following these steps, you should have a working to-do app where you can add tasks by typing in the input field and clicking the "Add Task" button.

Troubleshooting

• Issue: Nothing happens when I click "Add Task".

  • Solution: Ensure that your JavaScript file is linked correctly in the HTML and that you don’t have any console errors.

• Issue: Tasks don't appear.

  • Solution: Check if the event listener is set up correctly and that you are getting the value from the input field.

What's Next?

Now that you have a basic to-do app, consider enhancing it by adding features like:

• Task deletion
• Saving tasks to local storage
• Adding due dates

Conclusion

Creating a simple to-do app using GitHub Copilot is a straightforward way to familiarize yourself with coding while leveraging AI. Start with the basics, and you can evolve your app into something more complex as you learn.

What We Actually Use

For our personal projects, we typically use GitHub Copilot for quick prototyping. It's a great tool for beginners and helps speed up the coding process significantly, especially when you're stuck on syntax or need suggestions.
