bpmn-moddle
Read and write BPMN 2.0 diagram files in NodeJS and the browser.
bpmn-moddle uses the BPMN 2.0 meta-model to validate the input and produce correct BPMN 2.0 XML. The library is built on top of moddle and moddle-xml.
Usage
Get the library via npm package. Bundle it for the web using browserify or webpack.
var BpmnModdle = require('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
});
});Resources
