This Meteor package adds a login service which accepts a Facebook accessToken directly. Handy for case such as react-native where you don't want to use the usual oauth login pathway.
Call the login method with the following parameter:
{ facebookAccessToken: <access_token> }
The access token is verified with the Facebook Graph API's debug service.
As an extra bonus, the user profile and user document root is supplemented with a profilePictureURL field.
You must set up Facebook in your service configurations - this package has a dependency on the Facebook package. It loads your app secret and app ID from this configuration.
