How to implement a follows functionality

Question

I want to implement a feature that will allow a user to follow a topic or to subscribe to a topic and get notified when there is a new message in the topic. Any ideas?

Answer 1

You can use Push Notification in which you can create channels. Use can subscribe to channels and recieve message if somebody will post on the channel. See tutorial here

I am not sure this will address my use cases. For instance I want to show the user a list of objects that he is following.

I think you can look into Message/Queue Service (http://api.shephertz.com/app42-docs/message-queue-service/) to make it cross platform. You can make use of storage service (http://api.shephertz.com/tutorial/Saving-App-Data/?index=storage-data) if some functionality is not there.
