// NOTE: The contents of this file will only be executed if
// you uncomment its entry in "assets/js/app.js".
// To use Phoenix channels, the first step is to import Socket
// and connect at the socket path in "lib/web/endpoint.ex":
import {Socket} from "phoenix"
let socket = new Socket("/socket", {params: {token: window.userToken}})
// When you connect, you'll often need to authenticate the client.
// For example, imagine you have an authentication plug, `MyAuth`,
// which authenticates the session and assigns a `:current_user`.
// If the current user exists you can assign the user's token in
// the connection for use in the layout.
//
// In your "lib/web/router.ex":
//
// pipeline :browser do
// ...
// plug MyAuth
// plug :put_user_token
// end
//
// defp put_user_token(conn, _) do
// if current_user = conn.assigns[:current_user] do
// token = Phoenix.Token.sign(conn, "user socket", current_user.id)
// assign(conn, :user_token, token)
// else
// conn
// end
// end
//
// Now you need to pass this token to JavaScript. You can do so
// inside a script tag in "lib/web/templates/layout/app.html.eex":
//
// <script>window.userToken = "<%= assigns[:user_token] %>";</script>
//
// You will need to verify the user token in the "connect/2" function
// in "lib/web/channels/user_socket.ex":
//
// def connect(%{"token" => token}, socket) do
// # max_age: 1209600 is equivalent to two weeks in seconds
// case Phoenix.Token.verify(socket, "user socket", token, max_age: 1209600) do
// {:ok, user_id} ->
// {:ok, assign(socket, :user, user_id)}
// {:error, reason} ->
// :error
// end
// end
//
// Finally, pass the token on connect as below. Or remove it
// from connect if you don't care about authentication.
socket.connect()
// Now that you are connected, you can join channels with a topic:
// let channel = socket.channel("topic:subtopic", {})
// channel.join()
// .receive("ok", resp => { console.log("Joined successfully", resp) })
// .receive("error", resp => { console.log("Unable to join", resp) })
export default socket
