Introduction to Full-Stack Development 🌐

Welcome to the exciting world of Full-Stack Development - where you become the Swiss Army knife of web development! Full-stack developers are the versatile professionals who can build complete web applications from the ground up, handling everything from user interfaces to server logic and databases.

What is Full-Stack Development? 🤔​

Full-Stack Development refers to the practice of working on both the front-end (client-side) and back-end (server-side) portions of web applications. A full-stack developer is proficient in multiple programming languages, frameworks, and technologies across the entire web development stack.

The Full-Stack Architecture 🏗️​

The Complete Web Application Stack​

Frontend Technologies 🎨​

Core Technologies​

  • HTML5 - Structure and semantic markup
  • CSS3 - Styling, animations, and responsive design
  • JavaScript - Interactive functionality and dynamic behavior

Modern Frontend Frameworks​

// React Component Example
import React, { useState, useEffect } from 'react';

function UserProfile({ userId }) {
    const [user, setUser] = useState(null);
    const [loading, setLoading] = useState(true);
    
    useEffect(() => {
        fetchUser(userId)
            .then(userData => {
                setUser(userData);
                setLoading(false);
            })
            .catch(error => {
                console.error('Error fetching user:', error);
                setLoading(false);
            });
    }, [userId]);
    
    if (loading) return <div>Loading...</div>;
    
    return (
        <div className="user-profile">
            <img src={user.avatar} alt={user.name} />
            <h2>{user.name}</h2>
            <p>{user.email}</p>
            <p>Joined: {new Date(user.joinDate).toLocaleDateString()}</p>

    username: { type: String, required: true, unique: true },
    email: { type: String, required: true, unique: true },
    password: { type: String, required: true },
    createdAt: { type: Date, default: Date.now }
});

const User = mongoose.model('User', userSchema);

// Registration endpoint
app.post('/api/auth/register', async (req, res) => {
    try {
        const { username, email, password } = req.body;
        
        // Hash password
        const saltRounds = 10;
        const hashedPassword = await bcrypt.hash(password, saltRounds);
        
        // Create user
        const user = new User({
            username,
            email,
            password: hashedPassword
        });
        
        await user.save();
        
        // Generate JWT token
        const token = jwt.sign(
            { userId: user._id }, 
            process.env.JWT_SECRET, 
            { expiresIn: '24h' }
        );
        
        res.status(201).json({
            message: 'User created successfully',
            token,
            user: {
                id: user._id,
                username: user.username,
                email: user.email

    } catch (error) {
        res.status(400).json({ error: error.message });
    }
});

// Login endpoint
app.post('/api/auth/login', async (req, res) => {
    try {
        const { email, password } = req.body;
        
        // Find user
        const user = await User.findOne({ email });
        if (!user) {
            return res.status(401).json({ error: 'Invalid credentials' });
        }
        
        // Check password
        const isPasswordValid = await bcrypt.compare(password, user.password);
        if (!isPasswordValid) {
            return res.status(401).json({ error: 'Invalid credentials' });
        }
        
        // Generate token
        const token = jwt.sign(
            { userId: user._id }, 
            process.env.JWT_SECRET, 
            { expiresIn: '24h' }
        );
        
        res.json({
            token,
            user: {
                id: user._id,
                username: user.username,
                email: user.email
            }
        });
    } catch (error) {
        res.status(500).json({ error: error.message });
