How to get user id from a given mail

Question

I need to get the user ID when I input the mail of the user.

Is it possible?

Of course I have an authenticated user who is asking for the mail of a user already created.

I want to retrieve users like

var refer = firebase.auth ().ref ('[email protected]')
  refer.on ('value', function (snapshot) {
    console.log (snapshot.val());
  })

But in a possible way.

`firebase.auth ().ref ('[email protected]')` I don't think that is the `auth` service has a `ref()` method: https://firebase.google.com/docs/reference/js/firebase.auth.Auth. — Frank van Puffelen, Oct 17 '16 at 18:26
Aside from that: there is no API to look up the uid of a user based on their email address in Firebsae Authentication. If you need that functionality, you'll need to store the mapping yourself ; for example in the Firebase Database. — Frank van Puffelen, Oct 17 '16 at 18:30

Store the user info you want on a separate node in your database structure, then when the user asks for that, you retrieve from that endpoint.
