Parameters

• options: {
      maxSize?: number;
      filter?: (cmd: Command) => boolean;
      bus?: CommandBus<CommandMap>;
      undoAction?: string;
      redoAction?: string;
  } = {}

  • OptionalmaxSize?: number

  • Optionalfilter?: (cmd: Command) => boolean

  • Optionalbus?: CommandBus<CommandMap>

    Reference to the command bus — enables undo() to execute inverse handlers

  • OptionalundoAction?: string

    Action name to register as the undo trigger (e.g. 'cart.undo'). The plugin registers the bus handler itself and ALWAYS excludes this action from recording — even if filter would match it. Without this, a hand-wired bus.register('cart.undo', () => h.undo()) records the trigger command into history (clearing the redo stack and burying real entries), so undo works once and redo never enables. Requires bus.

  • OptionalredoAction?: string

    Action name to register as the redo trigger. Same semantics as undoAction.
