# A Socket handler
#
# It's possible to control the websocket connection and
# assign values that can be accessed by your channel topics.
## Channels
channel "pad:*", PoexWeb.PadChannel
#
# To create a channel file, use the mix task:
#
# mix phx.gen.channel Room
#
# See the [`Channels guide`](https://hexdocs.pm/phoenix/channels.html)
# for further details.
# Socket params are passed from the client and can
# be used to verify and authenticate a user. After
# verification, you can put default assigns into
# the socket that will be set for all channels, ie
#
# {:ok, assign(socket, :user_id, verified_user_id)}
#
# To deny connection, return `:error` or `{:error, term}`. To control the
# response the client receives in that case, [define an error handler in the
# websocket
# configuration](https://hexdocs.pm/phoenix/Phoenix.Endpoint.html#socket/3-websocket-configuration).
#
# See `Phoenix.Token` documentation for examples in
# performing token verification on connect.

# all active sockets and channels for a given user:
#
# Elixir.PoexWeb.Endpoint.broadcast("user_socket:#{user.id}", "disconnect", %{})
