> As of version `5.0.0` this library exposes [ES modules](http://exploringjs.com/es6/ch_modules.html#sec_basics-of-es6-modules). Use [esm](https://github.com/standard-things/esm) to consume it or an ES module aware bundler such as [Webpack](https://webpack.js.org) or [Rollup](https://rollupjs.org) to bundle it for the browser.
# bpmn-moddle
[![Build Status](https://travis-ci.org/bpmn-io/bpmn-moddle.svg?branch=master)](https://travis-ci.org/bpmn-io/bpmn-moddle)
Read and write BPMN 2.0 diagram files in NodeJS and the browser.
__bpmn-moddle__ uses the [BPMN 2.0 meta-model](http://www.omg.org/spec/BPMN/2.0/) to validate the input and produce correct BPMN 2.0 XML. The library is built on top of [moddle](https://github.com/bpmn-io/moddle) and [moddle-xml](https://github.com/bpmn-io/moddle-xml).
## Usage
Get the library via [npm package](https://www.npmjs.org/package/bpmn-moddle). Bundle it for the web using [browserify](http://browserify.org) or [webpack](https://webpack.github.io).
```javascript
import BpmnModdle from 'bpmn-moddle';
var moddle = new BpmnModdle();
var xmlStr =
'<?xml version="1.0" encoding="UTF-8"?>' +
'<bpmn2:definitions xmlns:bpmn2="http://www.omg.org/spec/BPMN/20100524/MODEL" ' +
'id="empty-definitions" ' +
'targetNamespace="http://bpmn.io/schema/bpmn">' +
'</bpmn2:definitions>';
moddle.fromXML(xmlStr, function(err, definitions) {
// update id attribute
definitions.set('id', 'NEW ID');
// add a root element
var bpmnProcess = moddle.create('bpmn:Process', { id: 'MyProcess_1' });
definitions.get('rootElements').push(bpmnProcess);
moddle.toXML(definitions, function(err, xmlStrUpdated) {
// xmlStrUpdated contains new id and the added process
});
});
```
