5 minute quick start

$ npm install -g smply
$ npx esbuild --bundle --format=esm --outfile=./toggler.js ./toggler.ts
$ smply machines create --machine toggler --node ./toggler.js
$ # You can now launch instances of your toggler machine, send events, and read state!

toggler.ts

import { createMachine } from "xstate";
import type { AllowRead, AllowWrite } from "@statebacked/machine-def";

export allowRead: AllowRead = ({ machineInstanceName, authContext }) =>
  machineInstanceName === authContext.sub

export allowWrite: AllowWrite = ({ machineInstanceName, authContext }) =>
  machineInstanceName === authContext.sub

export default createMachine({
  predictableActionArguments: true,
  initial: "on",
  states: {
    on: {
      on: {
        toggle: "off",
      },
    },
    off: {
      on: {
        toggle: "on",
      },
    },
