How realtime works?

I’m wondering how realtime works. For example, I have a data collection call news. How to monitor it and get notified if there is a new update.

Hi @kiptoomm, Thanks for the detailed response. One way you can implement that type of realtime update is by refreshing the view, when something in the database changes, here’s an example of the workflow:

1. Subscribe to a specific collection change in firestore
2. When the collection changes, refresh the view

Try something like this (this hasn’t been tested):

// On a <List /> view 
import { useRefresh } from "react-admin";
import firebase from 'firebase/app';

import * as firebase from "firebase/app";

const refresh = useRefresh();
// Watch collection
firebase.firestore().collection('my-collection').onSnapshot(a => {
  console.log('my-collection changed!');
  // This refreshes the list view
  refresh();
})

Let me know how it goes, Ben
