How to Use AI Coding Tools to Build a Simple Web App in 3 Hours

Building a web app can feel overwhelming, especially if you're a solo founder or indie hacker with limited time. You might wonder, "Can I really get something functional up and running in just three hours?" The answer is yes, especially if you leverage AI coding tools. These tools can streamline the development process, allowing you to focus on the big picture rather than getting lost in the code.

In this guide, I’ll walk you through the essentials of using AI coding tools to create a simple web app. By the end, you’ll have a working prototype and a clear understanding of the tools that can help you save time and effort.

Prerequisites: What You Need to Get Started

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

1. Basic Understanding of HTML/CSS/JavaScript: You don’t need to be an expert, but familiarity helps.
2. A Code Editor: I recommend Visual Studio Code (free) for its wide range of extensions.
3. An AI Coding Tool: We'll explore several options below.
4. A Hosting Platform: Basic hosting (like GitHub Pages) to deploy your app.

Step 1: Choose Your AI Coding Tool

Let’s compare some AI coding tools that can help you build your web app:

| Tool Name | Pricing | Best For | Limitations | Our Take | |-------------------|-----------------------------|---------------------------|------------------------------------------------------|---------------------------| | GitHub Copilot | $10/mo | Code suggestions | Limited to GitHub repos; may require a learning curve | We use this for most of our coding. | | Tabnine | Free tier + $12/mo pro | Autocompletion | May not understand complex context well | Good for quick snippets. | | Replit | Free tier + $7/mo pro | Collaborative coding | Limited features in the free tier | Great for team projects. | | Codeium | Free | Code generation | Limited language support | Worth trying for beginners. | | DeepCode | Free tier + $19/mo pro | Code reviews | May miss context in larger projects | Good for quality checks. | | Sourcery | Free tier + $12/mo pro | Code improvement | Limited to Python | Not our primary choice. |

What We Actually Use

We primarily use GitHub Copilot for its robust code suggestions and integration with our workflow.

Step 2: Set Up Your Development Environment

1. Install Visual Studio Code: Download and install it from the official site.
2. Add Your AI Tool: If you choose GitHub Copilot, install the extension from the marketplace.
3. Create a New Project: Set up a new folder for your web app and create an index.html, style.css, and script.js file.

Step 3: Build Your Web App

3.1: HTML Structure

Start by defining the basic HTML structure in your index.html:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <link rel="stylesheet" href="style.css">
    <title>My Simple Web App</title>
</head>
<body>
    <h1>Welcome to My Web App!</h1>
    <button id="clickMe">Click Me!</button>
    <div id="output"></div>
    <script src="script.js"></script>
</body>
</html>

3.2: CSS Styling

Next, add some basic styles in style.css:

body {
    font-family: Arial, sans-serif;
    text-align: center;
    margin: 50px;
}

button {
    padding: 10px 20px;
    font-size: 16px;
}

3.3: JavaScript Functionality

Finally, add functionality in script.js:

document.getElementById('clickMe').addEventListener('click', function() {
    document.getElementById('output').innerText = 'Button clicked!';
});

Step 4: Deploy Your Web App

1. Choose a Hosting Platform: For simplicity, we’ll use GitHub Pages.
2. Push Your Code: Commit your code to a GitHub repository.
3. Enable GitHub Pages: Go to your repository settings and enable GitHub Pages under the "Pages" section.

Troubleshooting: What Could Go Wrong

• Issue: The web app doesn’t display correctly.

  • Solution: Check your HTML structure and ensure all files are linked correctly.

• Issue: The button doesn’t respond.

  • Solution: Ensure your JavaScript file is correctly linked and that there are no syntax errors.

What's Next?

Now that you have a simple web app, consider these next steps:

• Add More Features: Use your AI tool to generate more complex functionalities.
• Gather Feedback: Share your app with friends or fellow builders for feedback.
• Iterate and Improve: Use the feedback to refine your app and consider deploying to a more robust hosting solution.

Conclusion: Start Here

If you’re looking to quickly build a web app, start with GitHub Copilot. It’s the most versatile tool for code generation and suggestions, and it integrates seamlessly into your workflow.

By following this guide, you can leverage AI coding tools to build a simple web app in just three hours. Remember, the key is to keep it simple and focus on functionality over perfection.
