xstate-event-emitter

What problem does it solve?

This Skill addresses the need to manage and communicate events that originate from within an XState machine and are intended for external listeners, decoupling internal state transitions from external side effects.

Core Features & Use Cases

• Emit Events: Use the emit() action creator to send events from machine transitions or actor logic.
• Subscribe to Events: Listen for emitted events using actor.on() with specific event types or a wildcard.
• Type Safety: Define and enforce types for emitted events using the setup configuration.
• Use Case: In a form submission machine, emit a toast event with a success or error message to be handled by the UI layer, without the machine needing to know how toasts are displayed.

Quick Start

Use the xstate-event-emitter skill to emit a 'notification' event with the message 'Form submitted successfully'.
