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
