About This Skill
This skill enables developers to design, implement, review, and migrate XState v5 statecharts in TypeScript applications. It provides support for modern v5 patterns, helping teams build predictable state machines and statecharts that keep code synchronized with visual diagrams. The skill is designed for developers working with complex state management who want to leverage XState's latest version for maintainable, readable state logic. It supports the full lifecycle of statechart development, from initial design through code review and migration from earlier XState versions.

Usage Examples
Prompt Template
Generate a state machine for [APPLICATION_NAME] using XState v5. Define states, events, and transitions for the [SPECIFIC_FEATURE] feature. Use TypeScript and include context for [DATA_SOURCE] and [USER_ACTIONS]. Ensure the machine handles edge cases like [ERROR_SCENARIO].
Example Output
```typescript
import { createMachine, assign } from 'xstate-v5';
type Context = {
userId: string;
data: any;
error: string | null;
};
type Events =
| { type: 'FETCH_DATA'; userId: string }
| { type: 'DATA_RECEIVED'; data: any }
| { type: 'DATA_ERROR'; error: string }
| { type: 'RETRY' };
export const dataFetchMachine = createMachine<Context>({
id: 'dataFetch',
initial: 'idle',
context: {
userId: '',
data: null,
error: null,
},
states: {
idle: {
on: {
FETCH_DATA: {
target: 'loading',
actions: assign({ userId: (_, event) => event.userId }),
},
},
},
loading: {
invoke: {
src: 'fetchData',
onDone: { target: 'success', actions: assign({ data: (_, event) => event.data }) },
onError: { target: 'error', actions: assign({ error: (_, event) => event.data }) },
},
},
success: {
on: {
FETCH_DATA: { target: 'loading' },
},
},
error: {
on: {
RETRY: { target: 'loading' },
FETCH_DATA: { target: 'loading', actions: assign({ error: null }) },
},
},
},
});
```
**Key Features:**
- **Idempotent Transitions**: Prevents duplicate data fetches.
- **Error Handling**: Gracefully handles API failures with retry logic.
- **Type Safety**: Fully typed events, context, and states.
- **Extensible**: Easy to add new states (e.g., `cancelled`) or actions.
**Next Steps:**
1. Use `useMachine` from `@xstate/react` to integrate this machine into your React component.
2. Add a `cancel` event to handle user-initiated cancellations.
3. Log errors to a monitoring service like Sentry for debugging.Find the right skills for your stack
