How to Build a Simple Web App in 2 Hours Using AI Code Assistance

Building web apps can often feel like a daunting task, especially for indie hackers and solo founders who might not have a deep technical background. The good news? With AI coding tools, you can create a simple web app in just two hours. In this guide, I’ll walk you through the process and share the tools you can use along the way.

Time Estimate

You can finish this in about 2 hours if you follow the steps closely.

Prerequisites

Before we dive in, here’s what you’ll need:

• A code editor like Visual Studio Code (VS Code)
• An account on a cloud platform like Vercel or Netlify for deployment
• Basic knowledge of HTML, CSS, and JavaScript (we're keeping it simple!)

Step-by-Step Instructions

Step 1: Define Your App Idea

First, choose a simple app idea. For this guide, let’s create a "To-Do List" web app. It’s functional, easy to build, and a great way to demonstrate the power of AI coding tools.

Step 2: Set Up Your Environment

1. Install Visual Studio Code: Download and install VS Code from here.
2. Create a New Project Folder: This will be where all your app files live.

Step 3: Use AI Coding Assistance

Here are the AI tools you can leverage to speed up your development:

| Tool Name | What It Does | Pricing | Best For | Limitations | Our Take | |-------------------|---------------------------------------------|-----------------------------|------------------------------|------------------------------------------------|-------------------------------------------| | GitHub Copilot | AI-powered code completion and suggestions | $10/mo | JavaScript, Python, Ruby | Limited to supported languages | We use this for quick coding suggestions | | Tabnine | AI-driven code completions | Free tier + $12/mo pro | Java, C++, JavaScript | May not understand complex context | Great for completing boilerplate code | | Replit | Online IDE with built-in AI assistant | Free tier + $7/mo pro | Quick prototyping | Limited features compared to desktop IDEs | Good for quick iterations | | Codeium | AI code assistant with multi-language support| Free | Various programming languages | Fewer integrations compared to others | Good for experimenting with new languages | | Ponicode | AI tool for unit tests | Free tier + $19/mo pro | JavaScript testing | Limited to JavaScript | Useful for ensuring code quality | | Sourcery | AI-powered code review and refactoring | Free tier + $12/mo pro | Python | Limited to Python only | We use this for improving code readability | | BuildAI | No-code AI app builder | Free tier + $25/mo pro | No-code solutions | Limited to app templates | Not for full custom apps | | DeepCode | AI-powered code review | Free | Java, JavaScript, Python | May miss some edge cases | Great for catching bugs | | Codex by OpenAI | Generate code from natural language prompts | Varies | Various | Requires OpenAI API key | Excellent for generating complex snippets | | CodeGPT | Generate code snippets from prompts | Free | Various | Sometimes lacks context for more complex tasks | Good for quick prototypes |

Step 4: Build Your App

1. Create Basic Files: In your project folder, create index.html, style.css, and app.js.

2. HTML Structure: Use GitHub Copilot to generate the HTML structure for your To-Do List app. Here’s a simple example:

   <html>
   <head>
       <link rel="stylesheet" type="text/css" href="style.css">
   </head>
   <body>
       <h1>To-Do List</h1>
       <input type="text" id="task" placeholder="Add a new task">
       <button onclick="addTask()">Add</button>
       <ul id="taskList"></ul>
       <script src="app.js"></script>
   </body>
   </html>
   

3. CSS Styling: Use Tabnine to suggest some basic styles. For example:

   body { font-family: Arial, sans-serif; }
   h1 { color: #333; }
   

4. JavaScript Functionality: Use CodeGPT to generate functions for adding and removing tasks. For example:

   function addTask() {
       const taskInput = document.getElementById("task");
       const taskList = document.getElementById("taskList");
       const newTask = document.createElement("li");
       newTask.textContent = taskInput.value;
       taskList.appendChild(newTask);
       taskInput.value = '';
   }
   

Step 5: Testing Your App

Once you have your basic app built, test it in your browser. Make sure tasks can be added and displayed correctly.

Troubleshooting Tips

• If something isn't working, check the console in your browser for error messages.
• Ensure all file paths are correct.

Step 6: Deploy Your App

1. Deploy to Vercel or Netlify: Create an account and follow their guides to deploy your app. Both platforms offer free tiers that are perfect for small projects.
2. Share Your App: Once deployed, you’ll receive a link to share your app with others.

What's Next?

Now that you have a simple web app up and running, consider expanding its functionality. You could add features like task completion, storage using local storage, or even user authentication.

Conclusion

Building a simple web app using AI coding tools can be done in about 2 hours. Start with a clear idea, use the right tools for coding assistance, and don’t hesitate to troubleshoot along the way.

What We Actually Use: In our experience, we rely heavily on GitHub Copilot for quick coding tasks and Tabnine for completing boilerplate code. If you're starting out, these tools will significantly speed up your workflow.
