How do I get a user's email address using accounts-facebook in Meteor?

Question

I created a Meteor app that allows users to sign on using Facebook. To do this, I'm using the accounts-ui and accounts-facebook packages. This works fine.

How do I retrieve the user's email address once they've signed on? I understand that this requires special permission, and so I added email as a "User & Friend's Permission" in the app settings on the Facebook developers site. Following the Meteor documentation, I also set up Account.ui.config like this:

Accounts.ui.config({
  requestPermissions: {
    facebook: ['email'],
  },
  passwordSignupFields: 'USERNAME_AND_EMAIL'
});

As expected, when a user of my app signs on using Facebook, it correctly asks them to share their email address. But how do I retrieve it? The user document has only the _id and profile.name.

Answer 1

The Facebook user's email address is stored in [userDocument].services.facebook.email, which is not published to the client, but can be accessed from the server or from the client using Meteor.methods and Meteor.call.
