        error: err
      });
    });
});
module.exports = router;

Please help me fetch username, id & mobile along with the token

Answer 1

Add those information while creating token.

const token = jwt.sign({
        username: users[0].username,
        email: users[0].email,
        userId: users[0]._id,
        mobile: users[0].mobile
      }, process.env.JWT_KEY,
        {
          expiresIn: "1h"
        }
      );

Also you should use mongoose "findOne" instead of using "find" it will allow you to use user object like "user.email" rather than dealing with array and doing "users[0]".
