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();
});

• Please star the repository on GitHub.
• File an issue if you find a bug. Or better yet...
• Submit a pull request to contribute.

Tests are located in the test/ folder. Load test/test.html in your browser of choice with any HTTP server you like (I use http-server). Tests are written in QUnit and are simple to understand.

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