@rulereplay/xstate

Bounded XState v5 path generation, execution, coverage, and model/runtime parity for RuleReplay.

Install

npm install --save-dev @rulereplay/core @rulereplay/xstate xstate

Example

import { fromMachine } from '@rulereplay/xstate';
import { checkoutMachine } from './checkout-machine.js';

const paths = fromMachine(checkoutMachine, {
  maxSteps: 8,
  events: [{ type: 'SUBMIT' }, { type: 'CANCEL' }],
});

Generated paths are explicitly bounded and serializable. The package can execute them against XState actors, track state/event/transition coverage, and compare the model with an independent runtime authority.

Requires Node.js 20.11 or newer and XState v5. Licensed under MIT.
