IMMEDIATE START - DELIVER IN 3 DAYS We require a nodejs developer to work on our server end to add passport facebook login. SCOPE Implement social login with Paspport Facebook functionality into our existing Loopback API framework. This involves full backend implementation; analysis; unit tests; admin web end and assist in integration with our mobile app. FUNCTIONALITY Loopback JS framework: 1. Implment passport-facebook functionality so that our user can login/register to our Native Mobile app backed by [login to view URL] 1. The implementation MUST support TOKEN access (not just session cookies) 3. The API should direct the caller to Facebook, login and then redirect back our our API server which will authenticate the details and register/login the Facebook authenticated user into our system and give them an access token (string) for future authenticated access (ie COOKIE and AUTHENTICATION TOKEN support) 6. Provide us a simple web based administrative end to the above so we can manage and disable users etc. 10.
