Write some Software

I would like some one to create a sample API with the following requirements. * API should authenticate the users via FB/Google from mobile. * Implementation difference in mobile is that the Access token would get generated at mobile end and we need to verify the Access token at our back end. * Once the user's authentication is complete at server end, a JWT token should be generated for authentication via passport JS. Tech stack * NodeJS * LoopBack [login to view URL] * API's authentication and authorization should be oauth 2.0 complaint * API's tokens should be JWT and not bearer tokens * Third party login, viz google, facebook etc to be handled using passport plugin for LoopBack.
