# bpmn-js - BPMN 2.0 for the web

[![Build Status](https://travis-ci.org/bpmn-io/bpmn-js.svg?branch=master)](https://travis-ci.org/bpmn-io/bpmn-js)

[bpmn-js](https://github.com/bpmn-io/bpmn-js) is a BPMN 2.0 diagram rendering toolkit and web modeler.

[![bpmn-js in action](https://raw.githubusercontent.com/bpmn-io/bpmn-js/master/resources/screencast.gif)](http://demo.bpmn.io/s/start)


## Usage

> No need for additional setup: Try out our [seed project](https://github.com/bpmn-io/bpmn-js-seed) or use the [pre-packaged version](https://github.com/bpmn-io/bower-bpmn-js) of the library.

Get the library via [npm](http://npmjs.org) or [Bower](http://bower.io/) and use it in your web applications to display [BPMN 2.0 diagrams](http://www.bpmn.org/).


```javascript
var BpmnViewer = require('bpmn-js');

var xml; // my BPMN 2.0 xml
var viewer = new BpmnViewer({ container: 'body' });

viewer.importXML(xml, function(err) {

  if (err) {
    console.log('error rendering', err);
  } else {
    console.log('rendered');
  }
});
```


## Installation

Fetch [bpmn-js prebuilt](https://github.com/bpmn-io/bower-bpmn-js) or install it via [npm](https://www.npmjs.com/package/bpmn-js).


#### Fetch Prebuilt

The [bower-bpmn-js](https://github.com/bpmn-io/bower-bpmn-js) repository contains pre-built bundles of bpmn-js. 

Download them directly _or_ fetch them with [Bower](http://bower.io/):

```
bower install bpmn-js
```

Checkout the [example project](https://github.com/bpmn-io/bpmn-js-examples/tree/master/simple-bower) to get started.


#### Install via npm

Fetch the library via npm to get fine grained access to the parts you need:
