xstate-typescript

To create type-safe XState v5 machines, use the `setup()` function to enforce type checking for context, events, input, output, actions, and guards, ensuring robust application logic.

XState v5 type safety requires TypeScript 5.0 or higher with strict null checks enabled to properly enforce type checking for your state machine's context, events, and actions.

Split XState machine configurations across files using the `createStateConfig()` helper, allowing you to modularize complex machine definitions while maintaining strict type safety for your state management.

Available type helpers include `ActorRefFrom`, `SnapshotFrom`, `EventFromLogic`, and `OutputFrom`, which provide type-bound utilities to robustly manage state machine actors and outputs in TypeScript.

You need type-safe state machines for complex user interfaces with intricate state transitions, such as multi-step form wizards or real-time data fetching components, to prevent runtime errors and improve developer experience.

Yes, XState v5 supports the actor model with TypeScript by enforcing type checking for events, input, and output across actors, utilizing type-bound helpers for robust state management.
