Context: I have a game that is client rendered via a live view with a custom hook. I am looking to persist a value to local storage so that the client side can re-hydrate its state on reconnect or refresh.
My live view gets set up via handle_params/3 and looks like
def handle_params(%{"id" => id, "name" => name}, _url, socket) do
case Games.get_active_room(id) do
nil ->
socket
|> put_flash(:error, "Game room #{id} not found")
|> push_navigate(to: "/")
|> then(fn socket -> {:noreply, socket} end)
%Room{} = room ->
Endpoint.subscribe(@current_game <> id)
Presence.track(self(), @current_game <> id, name, %{name: name})
Presence.track(self(), @all_players, "game_" <> id <> "_" <> name, %{name: name})
broadcast_readiness(@current_game <> id, game_ready?(id, room.num_players))
socket
|> push_event("set_game_id", %{id: nil})
|> assign(name: name)
|> assign(room_id: id)
|> assign(messages: %{})
|> assign(game_ready: false)
|> assign(winner: "")
|> assign_async(:answer, fn -> get_answer(id) end)
|> then(fn socket -> {:noreply, socket} end)
end
end
In the hook’s mounted callback, I have the following listener (which does not work):
this.handleEvent("set_game_id", function (game) {
console.log("set_game_id called");
console.log({ game });
});
However, after doing a little debugging, I realized that registering an event listener on the window does work:
window.addEventListener("phx:set_game_id", (e) => console.log(e));
Is there something I am missing with regards to getting this to work in the hook?
