React State Machines with XState v5

What problem does it solve?

This Skill addresses the complexity of managing intricate UI states, preventing bugs caused by boolean flag explosions, implicit state derivations, and invalid state transitions.

Core Features & Use Cases

• Finite States: Models UI behavior as explicit, mutually exclusive states (e.g., idle, loading, success, error).
• Context: Manages quantitative data associated with states (e.g., fetched data, form inputs).
• Events & Transitions: Defines how user interactions or system events trigger state changes.
• Guards & Actions: Enables conditional transitions and side effects during state changes.
• Invoked Actors: Manages long-running asynchronous processes like API calls with lifecycle support.
• Use Case: A user is filling out a multi-step form with complex validation and asynchronous data fetching between steps. This Skill ensures a robust and predictable user experience by managing the form's state transitions, validation status, and data loading.

Quick Start

Use the XState v5 setup() pattern to create a machine that fetches user data, handling loading and error states.
