Real-time comm. & event-driven arch. with Phoenix Channels & PubSub?

I’m working on a project and need to implement real-time communication and an event-driven architecture using Phoenix Channels and PubSub. I’m seeking guidance on best practices and approaches. Specifically, I’d like to know how to set up Phoenix Channels and PubSub for bidirectional real-time communication between clients and the server, as well as how to handle events and broadcasting efficiently. Any advice or resources would be greatly appreciated. Thank you!

Hey Snowwy76 welcome!

Phoenix channels are exactly that, right out of the box. If you’ve got a channel running, you have a bidirectional realtime connection between a client and a server.

Again out of the box you get a handle_event function, and broadcasting is generally well optimized.

Can you be more specific about your client / server communication patterns and what efficiency concerns you have?

Is the client a web browser or another application? If it’s the latter, something like slipstream or phoenix_gen_socket_client will be useful.
