View and edit BPMN 2.0 diagrams in the browser.

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

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);
}

Checkout our examples for many more supported usage scenarios.

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();

Prepare the project by installing all dependencies:

npm install

Then, depending on your use-case you may run any of the following commands:

# build the library and run all tests
npm run all
# spin up a single local modeler instance
npm start
# run the full development setup
npm run dev

You may need to perform additional project setup when building the latest development snapshot.

bpmn-js builds on top of a few powerful tools:

• bpmn-moddle: Read / write support for BPMN 2.0 XML in the browsers
• diagram-js: Diagram rendering and editing toolkit

It is an extensible toolkit, complemented by many additional utilities.
