Robot
A small functional and immutable Finite State Machine library. Using state machines for your components brings the declarative programming approach to application state.
See thisrobot.life for the main documentation.
import { createMachine, interpret, state, transition } from 'robot3';
let machine = createMachine({
  off: state(
    transition('toggle', 'on')
  ),
  on: state(
    transition('toggle', 'off')
  )
});
const service = interpret(machine, () => {
  render();
});

Robot works with a variety of UI libraries, and includes integrations for React, Preact, Haunted, and more. See the integrations page to learn more.
