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
{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.
