Subscribing to events from a Phoenix.Channel in 1.2.0-rc.0

test_channel.ex

defmodule MyApp.TestChannel do
  use MyApp.Web, :channel

  require Logger
  
  intercept ["some-event"]

  def join("test:lobby", _, socket) do
    # subscribe to a topic
    subscribe socket, "some-topic"
    {:ok, socket}
  end
  
  def handle_out("some-event", payload, socket) do
    Logger.info("some-topic:some-event called with #{inspect payload}")
    {:noreply, socket}
  end
  
end

# now anywhere else in the app we can broadcast an event which the channel can handle
MyApp.Endpoint.broadcast "some-topic", "some-event", %{ foo: "bar" }
