## Synopsis

  A finite state machine is a very good way to simplify a project when sequential logic is required. It helps your code to stay clean and easy to understand.

  It is an abstract machine that can be in one of a finite number of states. The machine is in only one state at a time; the state it is in at any given time is called the current state. It can change from one state to another when initiated by a triggering event or condition; this is called a transition. A particular FSM is defined by a list of its states, its initial state, and the triggering condition for each transition.

## Motivation

The main purpose of this library is to provide a simple way to handle sequential logics.

## Installation

### npm

```bash

$ npm i @lcluber/taipanjs

```

### yarn

```bash

$ yarn add @lcluber/taipanjs

```

## Usage

### ES6

```javascript

import { FSM } from '@lcluber/taipanjs';

const fsm = new Taipan.FSM([

  { name: 'greenOn',  from: 'red',  to: 'green' },

  { name: 'orangeOn', from: 'green', to: 'orange' },

  { name: 'redOn',    from: 'orange',  to: 'red' }

]);

function changeLight(light){

  const eventName = `${light}On`;

  if (fsm.transitionTo(eventName)) {

    // switchOff(); //switch lights off

    // switchOn(lights[light]); //switch requested light on

  }

}

```

### TypeScript

```javascript

import { FSM } from '@lcluber/taipanjs';

const fsm:FSM = new Taipan.FSM([

  { name: 'greenOn',  from: 'red',  to: 'green' },

  { name: 'orangeOn', from: 'green', to: 'orange' },

  { name: 'redOn',    from: 'orange',  to: 'red' }

]);

function changeLight(light: string){

  const eventName = `${light}On`;

  if (fsm.transitionTo(eventName)) {

    // switchOff(); //switch lights off

    // switchOn(lights[light]); //switch requested light on

  }

}

```

### IIFE

```html

```

```javascript

var fsm = new Taipan.FSM([

  { name: 'greenOn',  from: 'red',  to: 'green' },

  { name: 'orangeOn', from: 'green', to: 'orange' },

  { name: 'redOn',    from: 'orange',  to: 'red' }

]);

function changeLight(light){

  var eventName = `${light}On`;

  if (fsm.transitionTo(eventName)) {

    // switchOff(); //switch lights off

    // switchOn(lights[light]); //switch requested light on

  }

}

```

## API Reference

```javascript

export interface IEvent {

  name : string;

  from : string|boolean|number;

  to   : string|boolean|number;

}

export declare class FSM {

  state: string | boolean | number;

  events: Events;

  constructor(events: IEvent[]);

  transitionTo(eventName: string): boolean;

}

```
