Cloud Functions For Firebase - Write To Database When A New User Created

I am pretty new Cloud Functions for Firebase and the javascript language. I am trying to add a function every time a user created to write into the database. This is my code: const

Solution 1:

I found the problem. The problem is that shouldn't use the ${id}, and I shouldn't have use the child. So the code should look like this:

const functions = require('firebase-functions');
const admin = require('firebase-admin');

admin.initializeApp(functions.config().firebase);

exports.addAccount = functions.auth.user().onCreate(event => {
    const user = event.data; // The firebase user
    const id = user.uid;
    const displayName = user.displayName;
    const photoURL = user.photoURL;

    return admin.database().ref("/users/"+id+"/info/status").set("ok"); 
});
