Using GameChannel

defmodule TictactoePhxWeb.TictactoeChannel do
  use Garuda.GameChannel

  @impl true
  def on_join(_params, _socket) do
    IO.puts("Player Joined")
  end

  @impl true
  def on_rejoin(_params, _socket) do
    IO.puts("Player rejoined")
  end

  @impl true
  def authorized?(_params) do
    # Custom authorization code
    true
  end

  @impl true
  def handle_in("player_move", cell, socket) do
    # Handling usual events from client
    {:noreply, socket}
  end
end

You might have noticed that instead of use Phoenix.Channel, we are using Garuda.GameChannel.
