Im trying to create a user within Firebase and then create a user profile within the database on a web server. I have implemented the following code which creates the user quite nicely. However im not sure on how to receive the user id (which i need for a unique ID) to create the database structure. Is there a way to return a user object when the createUserWithEmailAndPassword is called?

I have tried to implement a firebase.auth().onAuthStateChangedfunction but i then receive a timeout error

If you havn't gathered this is for a web app.

<script>

function createUser() {

var Result = true;

var textUser = document.getElementById('userName').value;

var textPassword = document.getElementById('userPassword').value;

var textAccountID = document.getElementById('accountRef').value;

var textDateCreated = document.getElementById('dateCreated').value;

var textDisplayName = document.getElementById('displayName').value;

var UID;



firebase.auth().createUserWithEmailAndPassword(textUser, textPassword).catch(function(error) {

  // Handle Errors here.

  var errorCode = error.code;

  var errorMessage = error.message;

  return Result = false;

  // ...

});



writeUserData(UID, textDisplayName, textAccountID, textDateCreated);



return Result;



}



function writeUserData(userId, displayName, accountID, dateCreated) {

  firebase.database().ref('User/' + userId).set({

  userId:{

    AccountID: accountID,

    Created: dateCreated,

    Name: displayName}

  });

}





</script>
