bpmn-js - BPMN 2.0 for the web

View and edit BPMN 2.0 diagrams in the browser.

Installation

Use the library pre-packaged or include it via npm into your node-style web-application.

Usage

To get started, create a bpmn-js instance and render BPMN 2.0 diagrams in the browser:

const xml = '...'; // my BPMN 2.0 xml
const viewer = new BpmnJS({
  container: 'body'
});

try {
  const { warnings } = await viewer.importXML(xml);

  console.log('rendered');
} catch (err) {
  console.log('error rendering', err);
}

Dynamic Attach/Detach

You may attach or detach the viewer dynamically to any element on the page, too:

const viewer = new BpmnJS();

// attach it to some element
viewer.attachTo('#container');

// detach the panel
viewer.detach();
