    • Chromium 119.0.6045.9
    • Opera 103.0.4928.34

  • The library may work with the other browsers. They must at least support ES2015.

♻️ Usage

The library is available from NPM.
We support various module formats such as:

  • ESM: dist/bpmn-visualization.esm.js
  • IIFE: dist/bpmn-visualization.js and its minified companion dist/bpmn-visualization.min.js

📌 Usage in applications and projects

Install bpmn-visualization:

npm i bpmn-visualization

Then use this snippet to load your BPMN diagram in a page:

import { BpmnVisualization } from 'bpmn-visualization';

// initialize `bpmn-visualization` and load the BPMN diagram
// 'bpmn-container' is the id of the HTMLElement that renders the BPMN Diagram
const bpmnVisualization = new BpmnVisualization({ container: 'bpmn-container' });
let bpmnContent; // your BPMN 2.0 XML content

You can set the BPMN content using one of the following ways:

  • Copy/Paste directly the XML content in a variable
  • Load it from an url, like this example
  • Load from your computer, like the demo example

📜 TypeScript Support

The bpmn-visualization npm package includes type definitions, so the integration works out of the box in TypeScript projects. bpmn-visualization requires TypeScript 4.0 or greater. Past versions had the following requirements:

  • 0.21.0 to 0.27.1: TypeScript 4.5
  • 0.17.1 to 0.20.1: TypeScript 4.3

ℹ️ If you are looking for examples of projects integrating bpmn-visualization with TypeScript, see the bpmn-visualization-examples repository.


Prior version 0.27.0, bpmn-visualization required extra configuration for TypeScript projects as explained in the v0.26.2 README.

💠 Browser usage

In the HTML page:

  • Load bpmn-visualization (replace {version} by the recent version)
  • Define the container that displays the BPMN diagram, here bpmn-container
  • Load your BPMN diagram in a page
<script src="{version}/dist/bpmn-visualization.min.js"></script>
<div id="bpmn-container"></div>
  // initialize `bpmn-visualization` and load the BPMN diagram
  // 'bpmn-container' is the id of the HTMLElement that renders the BPMN Diagram
  const bpmnVisualization = new bpmnvisu.BpmnVisualization({ container: 'bpmn-container'});
  let bpmnContent; // your BPMN 2.0 XML content
