45-Day MERN Stack Challenge: Level Up Your Skills!

Listen to this Post

Week 1-2: JavaScript & TypeScript Basics

  • ES6+ Features:
    [javascript]
    // Example of arrow functions and async/await
    const fetchData = async () => {
    const response = await fetch(‘https://api.example.com/data’);
    const data = await response.json();
    console.log(data);
    };
    [/javascript]

  • TypeScript Fundamentals:

    interface User {
    id: number;
    name: string;
    }
    const user: User = { id: 1, name: 'John Doe' };
    console.log(user);
    

Week 3-4: Backend with Node.js & Express

  • REST APIs with Express.js:
    [javascript]
    const express = require(‘express’);
    const app = express();
    app.get(‘/api/data’, (req, res) => {
    res.json({ message: ‘Hello, World!’ });
    });
    app.listen(3000, () => console.log(‘Server running on port 3000’));
    [/javascript]

  • Authentication with JWT:
    [javascript]
    const jwt = require(‘jsonwebtoken’);
    const token = jwt.sign({ userId: 1 }, ‘secretKey’, { expiresIn: ‘1h’ });
    console.log(token);
    [/javascript]

Week 5-6: Frontend with React & Tailwind

  • React Hooks:
    [javascript]
    import React, { useState, useEffect } from ‘react’;
    const App = () => {
    const [data, setData] = useState([]);
    useEffect(() => {
    fetch(‘https://api.example.com/data’)
    .then(response => response.json())
    .then(data => setData(data));
    }, []);
    return
{data.map(item =>

{item.name}

)}

;
};
export default App;
[/javascript]

  • Tailwind CSS:
    </li>
    </ul>
    
    <div class="bg-blue-500 text-white p-4">
    This is a styled div using Tailwind CSS.
    </div>
    
    

    Week 7: Full-Stack Project Development

    • Connecting React with Express:
      [javascript]
      // React Fetch Example
      fetch(‘http://localhost:3000/api/data’)
      .then(response => response.json())
      .then(data => console.log(data));
      [/javascript]

    Final Week: Optimization & Deployment

    • Performance Optimization:
      [javascript]
      // Lazy Loading in React
      const LazyComponent = React.lazy(() => import(‘./LazyComponent’));
      const App = () => (
      <React.Suspense fallback={

      Loading…

      }>

      </React.Suspense>
      );
      [/javascript]

    What Undercode Say

    The 45-Day MERN Stack Challenge is a comprehensive roadmap for mastering the MERN stack, from JavaScript basics to full-stack development and deployment. By following this guide, you’ll gain hands-on experience with modern web development tools and techniques. Here are some additional Linux and Windows commands to enhance your workflow:

    • Linux Commands:
      – `curl http://localhost:3000/api/data` – Test your API endpoints.
      – `pm2 start server.js` – Manage your Node.js application with PM2.
      – `nginx -t` – Test your Nginx configuration before deploying.

    • Windows Commands:
      – `tasklist | findstr node` – Check if your Node.js server is running.
      – `netstat -an | find “3000”` – Verify if your Express server is listening on port 3000.
