How to connect data created in firestore with user who created this data?
I use the createUserWithEmailAndPassword
function to authorize user in firebase and after authorization I getting user data with onAuthStateChanged, but how could i connect particular user with data that is created only by them?
To create for example a profile document for a specific user, the common pattern is to use the user's UID as the document ID. Something like this:
import { getAuth, onAuthStateChanged } from "firebase/auth";
import { doc, setDoc } from "firebase/firestore";
const auth = getAuth();
onAuthStateChanged(auth, (user) => {
if (user) {
const uid = user.uid;
await setDoc(doc(db, "users", uid), {
name: user.displayName
});
// ...
}
});
