Firebase query to get users email registered with social login (js)

Question

What is on Firebase the query to get users email if they signed up using social login?

I'm using javascript, i know how to access database etc. but i'm not personally saving users email address, firebase does that automatically.

There is no client-side API to get a listing of users, as that would make it very easy to leak information about your users.

If you want to expose this information, you have two common options:

1. Store the information you want to expose in a database (such as the Firebase Realtime Database, or Cloud Firestore), and then access that from the app.
2. Create an endpoint (for example through Cloud Functions) that uses the Admin SDK to return a list of users.

Neither is pertinently better in all situations, although I believe the first one is a lot more commonly used.
