Learning Path to Become a Full-Stack Developer

1. Master the Fundamentals

Start with HTML, CSS, and JavaScript. Build simple static websites before moving to dynamic applications.

2. Choose a Front-End Framework

React.js is currently the most popular choice, but Vue.js and Angular are also excellent options.

3. Learn a Back-End Language

Node.js (JavaScript) is great for beginners since you can use the same language on both ends. Python (Django/Flask) is another beginner-friendly option.

4. Understand Databases

Start with a relational database like PostgreSQL, then explore NoSQL options like MongoDB.

5. Build Full-Stack Projects

Combine all your knowledge to create complete applications. Some project ideas:

6. Learn Deployment and DevOps

Deploy your projects using platforms like Heroku, Netlify, or Vercel. Learn basic Linux commands and server management.

Sample Full-Stack Application Code

Here's a simple Express.js server with React front-end integration: 

// Backend (server.js)
const express = require('express');
const app = express();
const PORT = 5000;

app.use(express.json());

app.get('/api/data', (req, res) => {
    res.json({ message: 'Hello from the backend!' });
});

app.listen(PORT, () => {
    console.log(`Server running on port ${PORT}`);
});

// Frontend (React component)
import React, { useEffect, useState } from 'react';

function App() {
    const [data, setData] = useState('');
    
    useEffect(() => {
        fetch('/api/data')
            .then(res => res.json())
            .then(data => setData(data.message));
    }, []);

    return (
        <div>
            <h1>Full-Stack App</h1>
            <p>{data}</p>
        </div>
    );
}

export default App;
