+// NOTE: The contents of this file will only be executed if

+
+// 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
