Enchufeweb

Enchufeweb is a websocket client library written in Elixir and based on the Erlang library websocket_client.

Installation

Add enchufeweb to your list of dependencies in mix.exs:

def deps do
[{:enchufeweb, "~> 0.2.1"}]
end

How to use it

• Implementation of the Websocket Client

  defmodule Client do
  use Enchufeweb
  def handle_message(data, state) do 
  IO.inspect data
  {:ok, state}
  end
  def handle_connection(_, state), do: {:ok, state}
  def handle_disconnection(_, state), do: {:close, "end", state}
  end

• Connect the client and send a message

  iex> {:ok, client} = Client.start_link([url: "ws://localhost:8888/websocket", ws_opts: %{conn_mode: :once}]) 
  iex> Client.ws_send(client, "Hola")

• Send a ping

  iex> Client.ws_send(client, :ping)

• Close the connection

  iex> Client.ws_send(client, :close)

• Client which will send a message just after the connection

  defmodule Client do
  use Enchufeweb
  def handle_message(data, state) do 
  IO.inspect data
  {:ok, state}
  end
  def handle_connection(_, state), do: {:reply, "Initial message", state}
  def handle_disconnection(_, state), do: {:close, "end", state}
  end
