I'm trying to do a very simple data load from firebase but it wont work when I use path segments in react
something very simple as
import { getFirestore, getDoc, getDocs, setDoc, doc, updateDoc, getCollection, collection } from "firebase/firestore";
import { firebaseConfig } from "config";
// Initialize Firebase
const app = initializeApp(firebaseConfig);
const firestore = getFirestore(app);
getDoc(doc(firestore, 'collection', ['path','to','document']));
it will throw an exception
Uncaught (in promise) TypeError: n.split is not a function
how can i do to pass an array for that function?
The doc() doesn't take an array as param but path segments (strings). Try using the spread syntax on array as shown below:
getDoc(doc(firestore, 'collection', ...['path','to','document']));
// spread syntax here ⬆
// Equivalent to:
getDoc(doc(firestore, 'collection', 'path', 'to', 'document'));
doc() function signature from the documentation:
export declare function doc(firestore: Firestore, path: string, ...pathSegments: string[]): DocumentReference<DocumentData>;
