SCION is an industrial-strength implementation of [W3C SCXML](http://www.w3.org/TR/scxml/) in JavaScript.

SCXML provides a declarative markup for Statecharts, a powerful modelling language for developing **complex, timed, event-driven, state-based systems**.

# Installation

## node.js

`npm install scxml`

## browser

### Script tag with cdnjs

Add the following script tags to your HTML:

```
<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/6.23.0/polyfill.min.js">
<script src="https://cdnjs.cloudflare.com/ajax/libs/scion/4.3.1/scxml.min.js">
```

Then SCION API available as global singleton object `scxml`.

### npm and browserify

Install babel-polyfill and scxml with npm:

`npm install --save scxml babel-polyfill`

Then add to your application entry point:

```js
require('babel-polyfill');
let scxml = require('scxml');
```

# Quickstart

```javascript
scxml.urlToModel("drag-and-drop.xml",function(err,model){

if(err) throw err;

model.prepare(function(err, fnModel) {

if(err) throw err;

//instantiate the interpreter
    var sc = new scxml.scion.Statechart(fnModel);

//start the interpreter
    sc.start();

//send the init event
    sc.gen({name:"init",data:rect});

});
})
```
