So far I have written the following code:
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;
return admin
.database()
.ref("/users/" + id)
.set("ok");
});
The idea here is to execute a cloud function once a new user gets created. As this happens, I want to create a new node in the Firestore database. Under the 'users' collection I want to add a document with the uid, which contains a bit of information, in this case a String that says 'ok'.
When deploying this function it produces an error. How exactly should I go about creating it?
The admin.database() returns the Realtime Database service. To use Firestore, use firebase.firestore(). Try refactoring the code as shown below:
exports.addAccount = functions.auth.user().onCreate((event) => {
const user = event.data; // The firebase user
const id = user.uid;
return admin
.firestore()
.collection("users")
.doc(id)
.set({ uid: id, ...user });
});
