Programming Phoenix LiveView: Broadcast Survey Results (page 237)
What is the difference between using PentoWeb.Endpoing.broadcast/3 and Phoenix.PubSub.broadcast/3. Also the same applies for subscribe/2
Before I read the book, I used to configure messaging system using Phoenix.PubSub.* and it was working fine actually. For example I create function in the context (boundary) call it subscribe and one call it broadcast like so:
defmodule Pento.Survey do
@topic inspect(__MODULE__)
def subscribe do
Phoenix.PubSub.subscribe(Pento.PubSub, @topic)
end
def broadcast({:ok, rating}, event) do
Phoenix.PubSub.broadcast!(
Pento.PubSub,
@topic,
{event, rating}
)
{:ok, rating}
end
# ... rest of code
end
