bpmn-visualization is a TypeScript library for visualizing process execution data on BPMN diagrams, with simplicity.

Based on the customization capability, it provides a set of diagram visualization features that includes additional display options for execution data (highlighting of some elements, adding customizable overlays, and more) as well as personalized interactive capabilities (mouse hover, click, and more).

We hope it will help you to create applications for process visualization and analysis 🙂

🌏 Browsers Support

| Chrome | Firefox | Safari | Edge | | :---------: | :---------: | :---------: | :---------: | | ✔️ | ✔️ | ✔️ | ✔️ |

Notes:

• Chromium based browsers should work (automatic tests are run with Chromium canary releases). In particular, the following desktop browsers are known working with [email protected]:
  • Brave 1.66.118
  • Chromium 125.0.6422.147
  • Opera 110.0.5130.66
• Support Chromium Edge but not Legacy Edge
• 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
try {
  bpmnVisualization.load(bpmnContent);
} catch (error) {
  console.error('Error loading BPMN content', error);
}

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.

NOTE

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="https://cdn.jsdelivr.net/npm/bpmn-visualization@{version}/dist/bpmn-visualization.min.js"></script>
...
<div id="bpmn-container"></div>
...
<script>
  // 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
  try {
    bpmnVisualization.load(bpmnContent);
  } catch (error) {
    console.error('Error loading BPMN content', error);
  }
</script>
