Sorry if this is a stupid question, but how can I get a token for authentication? 😄

Here is how I did it

var jwt = require('jsonwebtoken');
.
.
.
router.post('/login', function (req, res) {
    moduleUser.User.findOne({username: req.body.username}, function (err, user) {
        if (err)
            res.status(401).json({success: false, message: "Error"});
        if (user) {
            user.comparePassword(req.body.password, function (err, isMatch) {
                if (isMatch && !err) {
                    // Create token if the password matched and no error was thrown
                    var token = jwt.sign(user, 'my_secret', {expiresIn: 10000}); // in seconds
                    res.json({success: true, token: 'JWT ' + token});
                } else {
                    res.status(401).json({success: false, message: err});
                }
            })
        } else {
            res.status(401).json({success: false, message: "Invalid credentials"});
        }
    });
});
