drab v0.4.1 Drab.Socket
Drab operates on websockets. To enable it, you should inject the Drab.Channel into your Socket module
(by default it is UserSocket
in web/channels/user_socket.ex
):
defmodule MyApp.UserSocket do
use Phoenix.Socket
use Drab.Socket
end
This creates a channel “__drab:*” used by all Drab operations.
You may create your own channels inside a Drab Socket, but you can’t provide your own connect
callback.
Drab Client (on JS side) always connects at the page load and Drab’s built-in connect
callback will intercept
this call. If you want to pass the parameters to the Channel, you may do it in Drab.Client.js
, they
will appear in Socket’s assigns. Please visit Drab.Client
to learn more.
Drab uses the socket which is defined in your application Endpoint
(default lib/endpoint.ex
)
By default, Drab uses “/socket” as a path. In case of using different one, configure it with:
config :drab,
socket: "/my/socket"
