I have a confusion regarding Firebase observable in angular, here is structure

I want to watch all chats of particular user who logged in to my app, and I am seeing two option for achieve this.

Watch /chats node which means logged user will get notification for all users chats and I have to filter out logged user chats.
Watch multiple node like /chats/chatId , /chats/chatId .... so on, In this logged user will not get notification for all users chats, It will only get their own chats notification.

So which one will be good or if something better than this Please let me know.

I would say, its better to listen to chat node, chat.author equals . – rijin Dec 02 '18 at 14:33
@rijin But It would be bad for logged user to get all events from other users chats in case of watching full node /chat. – Nishant Dixit Dec 02 '18 at 15:04
you will be querying for a specific user, so how will you get all users messages? – rijin Dec 02 '18 at 15:07
@rijin I am taking about top-level `/chats` node not about `/user/id/chats` . – Nishant Dixit Dec 02 '18 at 15:28
and as you can see in `users/id/chats` there is mapping of logged users chats userId=>chatId, so I have to watch all these chatId in top-level `/chats`. – Nishant Dixit Dec 02 '18 at 15:30
Are you creating an app where multiple users can have chats with one person or many? ( https://stackoverflow.com/q/52218336/5675325 ) – Tiago Martins Peres Dec 07 '18 at 20:17
