BPMN Visualization

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

• additional display options for execution data (highlight some transitions, counters, and more)
• interactive capacities (mouse hover, click)

🎮 Demo and examples

Please check the ⏩ live environment.

You will find there basic usage as well as detailed examples showing possible rendering customizations.

🔆 Project Status

bpmn-visualization is actively developed and maintained.

Before the release of version 1.0.0, there may be some breaking changes. We avoid these as much as possible, and carefully document them in the release notes. As far as possible, we maintain compatibility for some minor versions.

🤩 Why using bpmn-visualization?

• ✨ True opensource license without watermark display
• ⚡️ Strong identity: the only BPMN viewer with a woman icon in the User Tasks
• 🎸 Fully documented and with a lot of integration examples
• 👓 Highly customizable rendering in a simple way
• 🔥 TypeScript support
• 🎯 Battle tested: high test coverage, thousands of tests, including tests on all supported browsers for Linux, macOS and Windows

🎨 Features

Already available features:

• Supported BPMN Elements.
• Navigate through the BPMN diagram
• Display options for execution data with interactive capacities

Planned features:

• Additional BPMN styling capabilities
• Library extension points

🌏 Browsers Support

We do our best to support recent versions of major browsers

Chrome	Firefox	Safari	Edge
✔️	✔️	✔️	✔️

Notes:

• Internet Explorer and Legacy Edge will never be supported.
• Chromium based browsers should work (automatic tests are run with Chromium canary releases). In particular, the following browsers are known working with [email protected]:
  • Brave 1.42.95
  • Chromium 104.0.5112.48
  • Opera 89.0.4447.83
• The library may work with the other browsers. They must at least support ES6.

♻️ Usage

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

• IIFE: dist/bpmn-visualization.js
• ESM: dist/bpmn-visualization.esm.js
• CommonJS: dist/bpmn-visualization.cjs.js

📌 Project usage

Install bpmn-visualization in the project:

npm i bpmn-visualization

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

import { BpmnVisualization } from 'bpmn-visualization';

let bpmnContent; // your BPMN 2.0 XML content
// 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' });
bpmnVisualization.load(bpmnContent);

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

bpmn-visualization provides type definitions, so the integration should work out of the box in TypeScript projects.

Depending on the build system used by the TypeScript project, it may get the following type errors:

• error TS2688: Cannot find type definition file for 'typed-mxgraph'
• error TS7016: Could not find a declaration file for module 'mxgraph'

In this case, declare the typed-mxgraph types in the tsconfig.json as in the following (see the typeRoots documentation for more explanations) 👇

{
  "compilerOptions": {
    "typeRoots": [
      "node_modules/@types",
      "node_modules/@typed-mxgraph"
    ]
  }
}

NOTE

This is also mandatory for users who want to extend the mxGraph integration.

Alternatively, you can set skipLibCheck to true in the tsconfig.json file, but this limits the definition checks.

ℹ️ For more details, see the TypeScript projects in the bpmn-visualization-examples repository.

💠 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>
  let bpmnContent; // your BPMN 2.0 XML content
  // 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'});
  bpmnVisualization.load(bpmnContent);
</script>
