问题 I'm new to angular and firestore and trying to figure out how to cast the data received from firebase directly to models. What is the best approach here? Currently I get the data, but it looks like it's not casted into a Blimp object. When I try to call getImageUrl() on it in the view, I get the following error message. ERROR TypeError: _v.context.$implicit.getImageUrl is not a function So my question: What is the best and cleanest way to cast these observables to the correct local model? I

问题 I have a problem with creating a communication between the external webpage and chrome extension. I suppose I need something like this. User tries to log in with login form on "example.com" using Firebase Auth (using google/Fb/email - password providers) If User logged in successfully, then the same credentials are sending to the chrome extension The extension calls signInWithCredential with taken credentials, and try to log in again If everything is ok, then User can work with firebase dB

问题 Simple version: When I register to onSnapshot in Firestore, is there a way to know if I am the client that pushed the update? Detailed Version: When a webpage is opened, it registers an onSnapshot callback to a Firestore collection called notes . The collection is then downloaded and stored in a local array var notes = [] . var window.notes = [] let notesRef = refs.db.collection('notes') notesRef.onSnapshot(querySnapshot => { querySnapshot.docChanges.forEach((docChange) => { switch (docChange

问题 According to answer below, Firebase-Admin is required to use FieldValue.serverTimestamp(). How do I get the server timestamp in Cloud Functions for Firebase with Firestore? . But I am using only Firebase JS and Firebase Firestore JS. The application runs only in client side. However, Firebase-Admin requires a server.
