Why it-fsm?

• 🚯 333 LOC - 0 dependencies
• 🍒 Sophisticated object-oriented design

Getting started

import { StateMachineBuilder } from "it-fsm";

const [locked, unlocked] = ["locked", "unlocked"] as const;

const sm = new StateMachineBuilder()
  .withStates([locked, unlocked])
  .withTransitions([
    [locked, { coin: unlocked }],
    [unlocked, { push: locked }],
  ])
  .build(locked);

You can find the full example in the examples folder.

Installation

Deno

if you use the Deno, just add following to your import_map.json

{
  "imports": {
    "it-fsm": "https://git.pleshevski.ru/pleshevskiy/it-fsm/src/commit/e3796c92639e3483a2a2a01a89912561561e796f/fsm.ts"
  }
}

or you can use branch instead https://git.pleshevski.ru/pleshevskiy/paren/raw/branch/main/

Note

: I recommend to use a specific commit instead of branch

Node.js

If you use the Node.js or in a browser as ES module, you may need to install it as follows, and additionally you can add import maps for client side.

npm install --save it-fsm
