A few endpoints to connect to:

• wss://echo.websocket.org/?encoding=text (the official test endpoint)
• wss://ws.postman-echo.com/raw (from Postman)
• wss://kobrakai.de/ws/connection_timer/blogpost (from the blog Bare WebSockets (with Elixir and Phoenix))

  use WebSockex

  def start_link(endpoint, parent) do
    WebSockex.start_link(endpoint, __MODULE__, parent, extra_headers: [])
  end

  def handle_frame({:text, message}, parent) do
    send(parent, {:websocket_message, message})
    {:ok, parent}
  end

  def handle_disconnect(%{reason: {:local, _reason}}, state) do
    {:ok, state}
  end

  def handle_cast(:close, state) do
    {:close, state}
