Engaging users and keeping them updated on the latest events is crucial to building a successful online community.
Because of this, Amity now supports updating various models through real time events whenever there is a status change in either community events, posts, comments, and user events.

For example, whenever a user updates their profile, this can be reflected automatically in another user’s device. This update will also be reflected in the same collection/community that the user is currently observing and participating in. Users can subscribe and unsubscribe to any particular topic to get updates, but they have to be a “member” of the community in order to perform these actions.
