Get started with jsonwebtoken CDN

const jwt = require('jsonwebtoken')({ signingKey: 'your-secret-key' }); // Initialize JWT with a secret key

// Function to generate a JWT token
function generateToken(payload) {
  const token = jwt.sign(payload, 'your-secret-key', { expiresIn: '1h' }); // Sign the payload with the secret key and set expiration time
  return token;
}

// Function to verify a JWT token
function verifyToken(token) {
  try {
    const decoded = jwt.verify(token, 'your-secret-key'); // Verify the token with the secret key
    return decoded;
  } catch (err) {
    return null;
  }
}

// Usage example
const payload = { sub: '1234567890', name: 'John Doe', iat: 1615137222 }; // Replace with your actual payload
const token = generateToken(payload);
console.log('Generated token:', token);

const decoded = verifyToken(token);
console.log('Decoded token:', decoded); // Should print the original payload
