Subscribe to Tauri events from your LiveView.

Bridges to Tauri's core event system via the LiveView hook — no extra plugin is required. Once subscribed, every occurrence of the event is forwarded to your LiveView as a "tauri_event" event, so native happenings (file drops, custom Rust events, plugin events) flow into handle_event/3 like any other UI event.

Requirements

• The TauriHook must be mounted in your LiveView (see ExTauri.Hook)
• Event permissions are part of core:default in src-tauri/capabilities/default.json (included by mix ex_tauri.install; older projects: mix ex_tauri.add window)

Drag and drop

Tauri delivers file drag-and-drop as built-in events:

def mount(_params, _session, socket) do
  socket = if connected?(socket), do: ExTauri.Event.subscribe(socket, "tauri://drag-drop"), else: socket
  {:ok, socket}
end

def handle_event("tauri_event", %{"event" => "tauri://drag-drop", "payload" => payload}, socket) do
  # payload["paths"] holds the dropped file paths
  {:noreply, assign(socket, :dropped, payload["paths"])}
end

Other built-in names: tauri://drag-enter, tauri://drag-over, tauri://drag-leave, tauri://focus, tauri://blur, tauri://resize, tauri://move, tauri://theme-changed.

Custom events from Rust

Any event emitted on the Rust side with app.emit("my-event", payload) can be subscribed to by name, giving your Rust code a direct line to LiveView.

Lifecycle

Subscriptions live on the hook element: they are cleaned up automatically when the user navigates away (the hook's destroyed callback unlistens). Re-subscribe in mount/3 as shown above.
