Quick start
Installation
1npm i @xstate/fsm
Usage (machine)
1import { createMachine } from '@xstate/fsm'; 2 3const toggleMachine = createMachine({ 4 id: 'toggle', 5 initial: 'inactive', 6 states: { 7 inactive: { on: { TOGGLE: 'active' } }, 8 active: { on: { TOGGLE: 'inactive' } } 9 } 10}); 11 12const { initialState } = toggleMachine; 13 14const toggledState = toggleMachine.transition(initialState, 'TOGGLE'); 15toggledState.value; 16const untoggledState = toggleMachine.transition(toggledState, 'TOGGLE'); 17untoggledState.value; 18// => 'inactive'
Usage (service)
1import { createMachine, interpret } from '@xstate/fsm'; 2 3const toggleMachine = createMachine({}); 4 5const toggleService = interpret(toggleMachine).start(); 6 7toggleService.subscribe((state) => { 8 console.log(state.value); 9}); 10 11toggleService.send('TOGGLE'); 12toggleService.send('TOGGLE'); 13toggleService.stop();
