bpmn-io/bpmn-js
Bpmn Js
bpmn-js is a browser-based BPMN 2.0 web modeler and rendering engine used for creating, editing, and visualizing business process models. It functions as an XML process modeler that parses BPMN 2.0 XML data into interactive visual diagrams within a web application.
The project distinguishes itself as a business process visualizer with capabilities for process flow simulation, which tracks token movement to mimic real-time execution. It also supports diagram version comparison to identify changes between model iterations and provides a layered overlay interface for binding metadata and custom UI elements to specific shapes.
The toolkit covers a broad range of modeling and rendering capabilities, including interactive model editing, visual model validation against predefined schemas, and the management of element properties via a dedicated interface. It features an extension system that allows for the integration of custom shapes, specialized logic modules, and custom visual styles.
The system utilizes SVG-based rendering and a command-pattern history tracking mechanism to manage modeling operations and their reversal.
Features
- BPMN 2.0 Web Modelers - Functions as a comprehensive browser-based tool for creating and editing BPMN 2.0 business process models.
- SVG-Based Vector Rendering - Translates logical BPMN models into scalable vector graphics for interactive browser-based visualization.
- BPMN 2.0 Process Modeling - Provides a full web-based editor for creating and modifying business processes using the BPMN 2.0 standard.
- Business Process Modeling Tools - Provides a sophisticated environment for creating and visualizing business workflow representations.
- XML Serialization - Converts structured model data back into well-formed BPMN XML string representations for storage.
- Object-to-XML Mapping - Maps BPMN XML data to internal object trees for manipulation and serializes them back to XML.
- BPMN 2.0 Rendering Engines - Provides a rendering engine that converts BPMN 2.0 XML into interactive visual diagrams in the browser.
- Diagram Renderers - Transforms XML process definitions into interactive visual graphical elements within the browser.
- Interactive Diagramming Libraries - Renders XML process data as interactive diagrams in the browser with built-in modification tools.
- Module-Based Extensions - Provides a modular extension system for registering specialized services and custom shapes into a shared registry.
- Modeler Logic Extensions - Integrates custom modules and services to introduce new elements, specialized rendering, or modeling rules.
- Visual Model Editors - Provides an interactive interface for modifying the structure and properties of BPMN diagrams directly in the browser.
- Visual Process Modelers - Implements a visual interface for manipulating the structure and properties of process models stored in XML format.
- Process Flow Simulations - Tracks token movement through a visual diagram to mimic and test real-time business process execution.
- Business Process Simulations - Simulates business process execution by tracking token movement through the visual diagram in real time.
- Visual Diagram Diffing - Visualizes structural and graphical differences between two versions of a BPMN model.
- Custom Element Registrations - Provides a registry for adding custom shapes and elements to represent concepts beyond the BPMN standard.
- Visual Data Rendering - Transforms complex BPMN XML data into visual graphical representations for browser-based analysis.
- Operational Command Histories - Captures modeling operations as discrete command objects to facilitate a reliable undo/redo history stack.
- Event Bus Systems - Utilizes an internal event-driven architecture to decouple core modeling logic from custom extensions.
- Model-Based State Validation - Validates the logical structure of diagrams against a predefined meta-model to prevent illegal modeling actions.
- Base Model Validations - Validates the internal state of the BPMN model against a set of defined constraints to ensure technical correctness.
- Undo-Redo Management - Implements a system for managing the editing timeline, allowing users to revert or repeat changes to the model.
- Interactive Diagram Embedding - Integrates interactive, navigable process views into web applications via dedicated components.
