20. client server socket

21. client server

22. client server join "lobby" send "room:42", "message", payload send "room:42",

    "message", payload socket send “lobby", "rooms", payload join "room:42"

23. socket client channel channel socket client channel channel

24. import Socket from "phoenix" socket = new Socket("/socket") socket.connect() room

    = socket.channel("room:elixir", payload) room.join()

25. room.push("some_event", payload) room.on("some_event", (payload) => { // ... })

26. defmodule MyEndpoint do socket "/socket", MySocket # ... end

27. defmodule MySocket do use Phoenix.Socket transport :websocket, Phoenix.Transports.WebSocket transport :longpoll,

    Phoenix.Transports.LongPoll channel "lobby", LobbyChannel channel "room:*", RoomChannel # ... end

28. defmodule RoomChannel do use Phoenix.Channel def join(topic, payload, socket) do

    # ... end def handle_in(event, payload, socket) do # ... end def handle_info(erlang_message, socket) do # ... end end

29. push(socket, event, payload) broadcast(socket, event, payload) broadcast_from(socket, event, payload)

30. on_some_ui_event(() => channel.push("user_message", payload)) channel.on("user_message", (payload) => render(payload))

31. defmodule RoomChannel do # ... def handle_in(event, payload, socket) do
