Easy way to request FB profile data after login?

[scutler19]

Is there an easy way to request Facebook Profile data without doing a full authentication? It seems like the only two functions are $auth.authenticate(provider) and $auth.link(provider). What if I just want to do something like $auth.getProfile(provider) to update a user's information (within the scope of my app) without having to relogin?

I'm using Node for the backend and I've structured my project like this example https://github.com/yhnavein/satellizer-sequelize
