JWT Authentication

npm install jsonwebtoken bcrypt

const jwt = require('jsonwebtoken');
const bcrypt = require('bcrypt');

// Hash password
const hashedPassword = await bcrypt.hash(password, 10);

// Generate token
const token = jwt.sign({ userId: user.id }, 'secret_key');

// Verify token
const decoded = jwt.verify(token, 'secret_key');
