How can determine the authenticated user who made the change within a Firestore 2nd gen trigger?
The 1st gen onUpdate trigger provides a change object & a context object where you can get the auth. The equivalent 2nd gen onDocumentUpdated instead only provides an event object which doesn't appear to include the auth user.
1st gen
export const onUserUpdate = Firestore
.document("users/{userId}")
.onUpdate(async (change, context) => {
const before = change.data.before.data();
const after = change.data.after.data();
// Access the authenticated user information
const user = context.auth;
if (user) {
console.log("Authenticated user ID:", user.uid);
console.log("Authenticated user email:", user.token.email);
console.log("Authenticated user name:", user.token.name);
// You can access more user properties as needed
} else {
console.log("No authenticated user information available.");
}
});
2nd gen
exports.onUserUpdate = onDocumentUpdated("user/{userId}", async (event) => {
const before = event.data.before.data();
const after = event.data.after.data();
// how do I get auth?
});
event: FirestoreEvent<Change<QueryDocumentSnapshot>
