How to Build a Simple CRUD App in 2 Hours Using AI Coding Tools

Building a CRUD (Create, Read, Update, Delete) app is a rite of passage for any aspiring developer. But let’s be honest: if you’re a solo founder or side project builder, you don’t always have the luxury of spending weeks on a project. Enter AI coding tools, which can help you whip up a functional CRUD app in just 2 hours. This guide will walk you through the essentials, tools, and pitfalls to avoid.

Prerequisites: What You Need Before You Start

Before diving in, ensure you have the following:

• A computer: Windows, macOS, or Linux will work.
• Node.js installed: Necessary for running JavaScript applications.
• Basic understanding of JavaScript: If you can write simple functions, you’re good to go.
• An IDE: Visual Studio Code is recommended for its extensions and ease of use.

Step-by-Step Guide to Building Your CRUD App

Step 1: Setting Up Your Environment (15 minutes)

1. Install Node.js: Download from Node.js official site.
2. Create a new project directory:

   mkdir my-crud-app
   cd my-crud-app
   

3. Initialize your Node.js project:

   npm init -y
   

Step 2: Choose Your AI Coding Tool (10 minutes)

Here’s a list of AI coding tools that can help you generate boilerplate code and streamline development:

| Tool Name | Pricing | Best For | Limitations | Our Take | |------------------|-------------------------------|---------------------------|-------------------------------------|-----------------------------------| | GitHub Copilot | $10/mo or $100/yr | Autocompleting code | Limited to popular libraries | We use it for quick suggestions. | | Tabnine | Free tier + $12/mo pro | Code completion | Less effective for niche languages | Good for JavaScript projects. | | Codeium | Free | Autocompletion | Limited integrations | Offers decent suggestions. | | Replit | Free tier + $7/mo pro | Full-stack development | Free tier has limited storage | Great for quick prototypes. | | Sourcery | Free | Code optimization | Focuses on Python | Not suitable for JS apps. | | CodeGPT | $19/mo | Generating functions | Requires a solid prompt | Useful for boilerplate. | | Ponicode | Free tier + $10/mo pro | Unit testing code | Limited to JavaScript | Good for testing while building. | | AI Dungeon | Free | Story-based coding | Not focused on practical coding | Fun but not for serious apps. | | Koder | $8/mo | Code generation | Works best with PHP | Useful for backend-focused apps. | | Jupyter Notebook | Free | Data-driven apps | Not ideal for web apps | Excellent for Python-centric CRUD. |

Step 3: Generate Your API (20 minutes)

Using GitHub Copilot, start generating your backend API. Here’s a simple example:

1. Install Express:

   npm install express
   

2. Create a basic server:

   const express = require('express');
   const app = express();
   app.use(express.json());
   
   const items = []; // In-memory storage
   
   app.post('/items', (req, res) => {
       items.push(req.body);
       res.status(201).send(req.body);
   });
   
   app.get('/items', (req, res) => {
       res.send(items);
   });
   
   app.listen(3000, () => {
       console.log('Server is running on port 3000');
   });
   

Step 4: Frontend Setup (30 minutes)

1. Choose a frontend framework: React is a solid choice.
2. Create your React app:

   npx create-react-app my-crud-frontend
   cd my-crud-frontend
   

3. Install Axios for API calls:

   npm install axios
   

Step 5: Connect Frontend to API (30 minutes)

In your React app, set up Axios to connect to your API:

import axios from 'axios';

const fetchData = async () => {
    const response = await axios.get('http://localhost:3000/items');
    console.log(response.data);
};

Step 6: Test Your CRUD Operations (15 minutes)

Use Postman or a similar tool to test your API. Make sure you can create, read, update, and delete items.

Troubleshooting: What Could Go Wrong

• CORS issues: If your frontend can’t access your backend, you may need to set up CORS middleware in Express.
• Unexpected errors: Check your console for errors and debug accordingly.

What's Next?

Once your CRUD app is up and running, consider adding user authentication, deploying your app, or enhancing the UI.

Conclusion: Start Here
