Send data to firebase cloud function - firebase

Question

I'm using firebase cloud function to add users to my database after they register.
I want to add (when user is created) a nickname for example.
In the register form, there is a box for nickname, but how can I send it the firebase function so it would be added to the user in the database?
This is firebase function:
const functions = require('firebase-functions');
const admin = require('firebase-admin');
admin.initializeApp(functions.config().firebase);
const ref = admin.database().ref()
exports.createUserAccount = functions.auth.user().onCreate(event=>{
const uid = event.data.uid
const email = event.data.email
const photoUrl = event.data.photoUrl || 'https://vignette1.wikia.nocookie.net/paulblartmallcop/images/9/9c/Person-placeholder-male.jpg/revision/latest?cb=20120708210100'
const newUserRef = ref.child(`/users/${uid}`)
return newUserRef.set({
photoUrl: photoUrl,
email: email,
})
});
The register form is in another file (register.js), how can I send data from there to the function?
I do not call createUserAccount anywhere, it is triggered when this function happens:
handlePress = (navigation)=>{
if(this.state.password == this.state.verify){
firebaseRef.auth().createUserWithEmailAndPassword(this.state.email, this.state.password).then((newUser)=>{
const resetAction = NavigationActions.reset({
index: 0,
actions: [
NavigationActions.navigate({ routeName: 'Home'})
]
})
navigation.dispatch(resetAction)
}).catch(function(error){
console.log(error);
});
}else{
//password not match, show error.
}
}
Thanks in advance!

Answer 1

You don't have to use a firebase cloud function to add a nickname to the user (If the user is already created).
Just call from your js :
ref.child("users").child(uid).child("nickname").set(nickname);
Other solution
You can create the user only when the nickname is filled. You can save it in the user.displayName and access to it from your onCreate trigger.
exports.createUserAccount = functions.auth.user().onCreate(event=>{
const user = event.data; // The Firebase user.
const uid = user.uid;
const email = user.email;
const nickname = user.displayName;
const photoUrl = user.photoUrl || 'https://vignette1.wikia.nocookie.net/paulblartmallcop/images/9/9c/Person-placeholder-male.jpg/revision/latest?cb=20120708210100';
const newUserRef = ref.child('/users/${uid}');
return newUserRef.set({
nickname: nickname,
photoUrl: photoUrl,
email: email
});
});
