I'm trying to get a unique key from the push function but whenever I call it I get this error: Uncaught TypeError: postsRef.push is not a function at HTMLFormElement. These are my imports:
import { initializeApp } from "https://www.gstatic.com/firebasejs/9.6.6/firebase-app.js";
import { getDatabase, set, ref, update, onValue, remove, push } from "https://www.gstatic.com/firebasejs/9.6.6/firebase-database.js";
import { getAuth, createUserWithEmailAndPassword, signInWithEmailAndPassword, onAuthStateChanged, signOut } from "https://www.gstatic.com/firebasejs/9.6.6/firebase-auth.js";
And these are the lines that I use to call the push function:
const app = initializeApp(firebaseConfig);
const db = getDatabase(app);
const postsRef = ref(db, 'devices/');
const newPostRef = postsRef.push();
I hope you guys can help me, thank you
CodePudding user response:
push
is nowadays a top-level function, and no longer a method in a reference.
Since you're already importing push
, you can use it as:
const newPostRef = push(postsRef);
The change is very mechanical here: changing from object.operation()
to operation(object)
, which is a common pattern when moving over from older Firebase SDK to v9 and above.
