Firebase Returning user object after account creation

Looks like firebase has made some changes on this method. The accepted solution needs a little fix:

firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(data){
  console.log('uid',data.user.uid)

  //Here if you want you can sign in the user
}).catch(function(error) {
    //Handle error
});

Now you get to acces the user via data.user

Hope this helps :)

The createUserWithEmailAndPassword() function returns a so-called Promise, which has methods catch() and then(). You're already using catch() to handle problems. To handle "non-problems", you need to use then():

firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(user) {
  console.log(user); // see https://firebase.google.com/docs/reference/js/firebase.User
})
.catch(function(error) {
  // Handle Errors here.
  var errorCode = error.code;
  var errorMessage = error.message;
  return Result = "false";
  // ...
});

See the reference documentation for createUserWithEmailAndPassword and for firebase.User.

In order to get the user id in the client side you should do this:

firebase.auth().createUserWithEmailAndPassword(textUser, textPassword)
.then(function(user){
  console.log('uid',user.uid)

  //Here if you want you can sign in the user
}).catch(function(error) {
    //Handle error
});

as it is described here:

https://firebase.google.com/docs/reference/js/firebase.auth.Auth#createUserWithEmailAndPassword

Returns non-null firebase.Promise containing non-null firebase.User
