Server Sent Event to a specific user

[Thai Tran]

Hi,

I am working on a message sending/reading app atm. Is there any way to push a message to a particular user session by using Redis and SSE ? I am using the tutorial at https://github.com/fcurella/django-push-demo and it works great with the current setup (which means I can send the whole bunks of new messages to all users but this is not what I wish for, obviously). When a user A composes a message and send to user B, how can I just "push" that new message to that particular user B ?

Well You can always send custom events for some specific channel. Example:

socket.on("global_event", function(channel, data) {});

socket.on("user_XYZ", function(channel, data) {});

emit_to_channel('some_room', 'gobal_event', 'hello')

emit_to_channel('some_room', 'user_XYZ', 'hello XYZ')

I understand this is not the most secure way but you can ensure additional encryption like hashing on every request or shit like that or even have every user connects to its own "secured" channel. 

Hope this helps.

Yes, that was what I thought. But letting the user subscribe to a channel without any validation / authorization is a bit scary. That is why I wanna push the message based on the user session, not through a user name or strings like that

If timing requirements permit, you could let the client side request
messages frequently enough to satisfy users. I think that would be
nicely low-tech and somewhat tune-able.
