Best for

▸Multi-step form wizard with branching logic and validation states
▸Media player controls with loading, playing, paused, buffering states
▸Real-time collaboration features with online/offline/syncing user states
▸Shopping cart checkout flow with payment, shipping, confirmation steps
▸Authentication flows with login, verification, password reset sequences

What you'll get

●XState machine definition with hierarchical states, guarded transitions, and TypeScript types for a form wizard
●Statechart visualization with parallel regions for independent UI concerns like validation and autosave
●React component integration showing XState machine usage with proper event handling and state subscriptions

Not designed for ↓

×Simple boolean toggles or basic show/hide component state
×Basic CRUD operations without complex workflows
×Static content websites without interactive state transitions
×Server-side business logic or backend state management

Expects

Complex UI workflows with multiple states, impossible state combinations, or multi-step processes that need formal modeling.

Returns

XState machine configurations with states, transitions, guards, actions, and TypeScript integration for predictable UI behavior.
