Events

Subscribe to toast lifecycle events for analytics, debugging, and UI reactions.

Toastflow emits lightweight events through subscribeEvents.

Event types are defined in packages/core/src/types.ts — look for ToastEvent and ToastEventKind.

const off = toast.subscribeEvents((event) => {
  console.log(event.kind, event.id);
});

off();

Event Kinds

Kind	Emitted when
`duplicate`	`show(...)` found an existing match while `preventDuplicates: true`
`timer-reset`	Visible toast timer was reset (update or resume with `pauseStrategy: "reset"`)
`update`	`update(id, options)` succeeded

Actions

Store methods for showing, updating, dismissing, and managing toasts.

State

Toast state structure, lifecycle phases, and reactive subscriptions.
