A basic example of express server with JWT authentication (passport.js) and user entity handled by Mongoose
The authentication is jwt based. I use passport with passport-local and passport-jwt strategies in order to handle the authentication with the basic email / password fields.
When a user is authenticated, the jwt token is sent to the client which has to store it. When the client wants to access to a restricted route, the client must provide the jwt token in the header request.

You need put the jwt token in the request header, using Authorization key field and concat "JWT " + jwtToken in the value field.

This example required bcrypt npm module. On Windows OS, bcrypt is really painful to install. So feel free to replace this module with this one !
