Live Queries subscription updates in Parse-server #4905
Description
let query_add = new Parse.Query("class-name");
let subscription = query_add.subscribe();
subscription.on('update', (obj) => {
alert('object updated');
});
Is it possible to get subscription alerts for live queries on a single client instead of everyone. I am using the following code to get update alerts for the object 'obj' on class 'class-name'. But the alert message comes on every client( i.e every instance of running app). How can I modify this to notify only the single client
