Nodejs working with JWT (JSON Web Token)

npm install jsonwebtoken

var jwt = require('jsonwebtoken');

var auth = {
    id : id,
    name : 'moin',
    email : 'mastermoin409@gmail.com',
} 

var token = jwt.sign({ authToken: auth }, 'shhh.....', {expiresIn : 1800});


'shhh.....' is private key or secret key of your application, it is normally string

1800 is  token expiry time
