This project has been superseded by bpmn-io/bpmn-js.


camunda BPMN JavaScript libraries for parsing, executing and rendering BPMN 2.0 with JavaScript.


  • Transformer - Supports parsing a BPMN 2.0 XML File and transforming it into a JavaScript object model. The same object model can then be passed to the Executor and the Renderer.
  • Engine - Lightweight Process Engine completely written in JavaScript.
  • Renderer - Allows rendering BPMN 2.0 Diagrams using SVG or HTML5 Canvas.

Getting Started

The entry point to the API is the Bpmn Class.

Bootstrapping the Renderer

The Renderer uses Dojo GFX for abstracting SVG and HTML5 Canvas as underlying graphics technology. Additionally it relies on jQuery for DOM manipulation.

You must first include a AMD compliant script loader, such as Dojo or RequireJS.

To use plain RequireJS, download and include it into the site:

<script src="lib/require/require.min.js"></script>

Now you need to configure the path to the dependencies dojo, dojo.gfx and jquery in a require config. Assuming that the camunda-bpmn.js libraries are located under lib/camunda-bpmn and dojo is stored under lib/dojo:

<script src="lib/jquery/jquery-1.7.2.min.js"></script>

<!-- found in project as build/bpmn.min.js -->
<script src="lib/camunda-bpmn/bpmn.min.js"></script>

<!-- or include minified engine, if you need only that -->
<script src="lib/camunda-bpmn/engine.min.js"></script>
  baseUrl: "./",
  packages: [
    { name: "dojo", location: "lib/dojo/dojo/" },
    { name: "dojox", location: "lib/dojo/dojox" }

Finally, you can load the renderer and draw a process diagram.

require([ "bpmn/Bpmn" ], function(Bpmn) {
  new Bpmn().renderUrl("test/resources/task_loop.bpmn", {
    diagramElement : "diagram",
    overlayHtml : '<div style="position: relative; top:100%"></div>'
    bpmn.annotate("reviewInvoice", '<span class="bluebox"  style="position: relative; top:100%">New Text</span>', ["highlight"]);


Check out the file src/bpmn/Bpmn.js for the API of the library.


We are using Grunt for building and testing the code. It can be installed using:

  1. Install node.js.
  2. Open a terminal, navigate to the site/ folder and type npm install
  3. Install Grunt's command line interface (CLI) globally using npm install -g grunt-cli

After Grunt is installed you can use it like this:

  1. Run grunt requirejs to optimize and minify the JavaScript code into the build/ folder.
  2. Run grunt server watch to start a web server at localhost:9000
  3. Open localhost:9000/test/runner.html to execute the jasmine tests in your browser while running the grunt server.
  4. Open localhost:9000/demo.html to see the demo.
