Hello @mohamedismael after the investigation, it appears that in some features you are required to subscribe to the real-time event, please see the sample steps below:

  1. You need to get a topic of real-time event from this example
    ASC Sample Code

  2. Add the topic from #1 to EventSubscriberReposity same as the example
    ASC Sample Code

  3. After #1 and #2 real-time event service will send an event to the client automatically (*.on('dataUpdated') will work as expected, please see sample code here ASC Sample Code )

Note: Please don’t forget to do unsubscribe when user proceed to change the page or when real-time events are not required

Hey @mohamedismael

You would need to individually subscribe to the posts returned in the response for queryPosts.

Also, you would need to subscribe to the appropriate topic based on targetType.

There are 2 types of posts: user posts and community posts. If user posts a post in the community it’s a community posts, other way it is user post. Community posts appear in community feeds, user posts in user feeds.

To receive post updates for the user you should do:

import { 
  UserRepository, 
  getUserTopic, 
  SubscriptionLevels, 
  EventSubscriberRepository,
} from '@amityco/js-sdk';

let user;
const liveUser = UserRepository.userForId('abc');

liveUser.on('dataUpdated', model => {
  user = model;
});

// once you have user model you can subscribe to the topic to receive updates for all posts appeared in the user feed 

const topic = getUserTopic(user, SubscriptionLevels.POST);
EventSubscriberRepository.subscribe(topic);

Community:

let community;
const liveCommunity = CommunityRepository.communityForId('abc');

liveCommunity .on('dataUpdated', model => {
  community= model;
});
...
const topic = getCommunityTopic(community, SubscriptionLevels.POST);
EventSubscriberRepository.subscribe(topic);

The queryAllPosts gives you back a mix of posts from different user feed and community feeds. To be notified that some post is created in general you should subscribe by hand for every user and community you want receive updates from.

For you case, I suppose it’s enough to subscribe to

const topic = getUserTopic(user, SubscriptionLevels.POST);

Where user is your user.

There is no unique topic for queryAllPosts which gives update for everything.
