BPMN visualization library usage examples

BPMN Visualization Examples

This repository contains examples showing how to use bpmn-visualization.

🎮 Live Environment

Give a try to the ⏩ live environment to quickly have an overview of the bpmn-visualization capabilities.

You will find both

• demos: show what you can do with bpmn-visualization in various use cases, in dedicated user oriented situations
• examples: demonstrate how to use a single feature.

📖 Getting BPMN Diagrams

Some examples require loading local files. If you are looking for BPMN diagram files, you can use resources from:

• the BPMN Model Interchange Working Group (BPMN MIWG, an initiative "to support, facilitate, and promote the interchange of BPMN Models"
  • bpmn-miwg-test-suite
  • bpmn-miwg-demos
• the Process Analytics project
  • BPMN diagrams of the bpmn-visualization-examples repository
  • BPMN diagrams used in the tests of bpmn-visualization

🖥️ Running examples locally

Some examples and demos may load ES Modules; in that case, you cannot open html pages directly from your local disk.

For instance, on Chrome, the Console would display the following errors

Access to script at 'file:///...../bpmn-visualization-examples/examples/my-file.js' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, https. index.html:1
Failed to load resource: net::ERR_FAILED utils.js:1

To access such examples, you need to run a local web server and then access the examples via the http protocol. We advise to make the local web server serve the whole repository, to also be able to access to the demo (resources available in the ./demo folder).

Go to the repository root and use one the following solutions

• python2: python -m SimpleHTTPServer 8001 and go to http://localhost:8001/examples/
• python3: python3 -m http.server 8002 and go to http://localhost:8002/examples/
• nodejs/npm: npx http-server --port 8003 -o ./examples and your default web browser opens http://localhost:8003/examples/
• .... your own lovely web server

🚸 Prerequisites for reuse in projects

Some examples are provided for direct use in the web browser. If you want to integrate their related code in a project, adaptations may be required.

You can check the examples projects in this repository or the Live IDE examples to know how to bootstrap bpmn-visualization in a project.

TypeScript users should also read the paragraph about the TypeScript support in the bpmn-visualization README.

👁️‍🗨️ Demos

• Load and Navigation demo - shows several features of bpmn-visualization at the same time. The sources of the demo are available in the bpmn-visualization repository.
• Hacktoberfest themes - special Hacktoberfest diagram with Hacktoberfest colors
• Monitoring of all process instances demo - show how to use bpmn-visualization to render the monitoring of all process instances for a defined process

🔭 Examples

bpmn-visualization usage in browsers

Basic examples

• Add stylized overlays - add stylized overlays on BPMN elements
• Custom overlay default style - custom default style of the overlays

Custom BPMN Theme examples

DISCLAIMER: extension points are currently very experimental and are subject to change.
They are mainly hacks to let you see what will be later available in a more integrated way.
Custom BPMN Theme features will be progressively added to bpmn-visualization. See the Extensions Milestone.

• Custom user task icon - use your own icon
• Custom colors - custom defaults, specific to BPMN element types
• Custom edge marker colors - custom colors for Edge start and end markers

• Attach tooltip and popover to BPMN elements - interact with the BPMN Diagram to display additional information
• Select elements by BPMN kind - to select elements by BPMN kind and register custom behavior on found elements
• Open a call activity from a main BPMN Diagram on a modal - interact with a diagram to open the details of a Call Activity on a modal
• Open a call activity from a main BPMN Diagram on a tab (of the page) - interact with a diagram to open the details of a Call Activity in a tab (of the page)
• Open a call activity from a main BPMN Diagram on the same container - interact with a diagram to load the details of a Call Activity in the same container
• Growing Sequence Flow - add custom growing animation on a Sequence Flow
• Running Dashed Message Flow - add custom running dashed animation on a Message Flow

Miscellaneous examples

Playgrounds in live IDE

• CodeSandbox bpmn-visualization JavaScript Template - Play with the bpmn-visualization JavaScript API. Use the template to demonstrate missing features or bugs.
• CodeSandbox bpmn-visualization TypeScript Template - Play with the bpmn-visualization TypeScript API. Use the template to demonstrate missing features or bugs.
