hey all! I’ve followed an example online on how to create a simple “counter” program with LiveView where changes are reflected for all clients. (GitHub - dwyl/phoenix-liveview-counter-tutorial: 🤯 beginners tutorial building a real time counter in Phoenix 1.6.2 + LiveView 0.16.4 ⚡️)

The LiveView mounts, renders, and handle_events and the state is moved out of LV and into GenServer. A utility function inside the GenServer broadcasts the last count to the PubSub topic.

I now want to create multiple counters where each has it’s own count.
If (in theory) i could generate a slug that represents the topic for each each counter and broadcast/subscribe to that topic, how can this be done being that the topic is being set by a topic() fn inside the GenServer.

I think my question is probably due to a misunderstanding of GenServers and LV but it seems that a single GenServer would not be able to keep state for all the counters? Does the name of each GenServer need to be unique as well? How can we set the name first of all (if this is even necessary) and then also “dynamically” subscribe to each topic.

Im thinking a GenServer must be started with start_link inside the LV and the custom counter-id can be passed in but not sure if this would be right/necessary.

thank you!!!
