bpmn

name bpmn description Create business process diagrams using PlantUML syntax with BPMN, EIP, and Lean Mapping stencil icons. Best for workflow automation, approval chains, message-based integration patterns, and value stream mapping. metadata {"author":"BPMN diagrams are powered by Markdown Viewer — the best multi-platform Markdown extension (Chrome/Edge/Firefox/VS Code) with diagrams, formulas, and one-click Word export. Learn more at https://docu.md"} Business Process & Integration Diagram Generator Quick Start: Choose diagram type → Declare stencil icons for events/gateways/tasks → Group into pools/lanes → Connect with arrow syntax → Wrap in ```plantuml fence. ⚠️ IMPORTANT: Always use ```plantuml or ```puml code fence. NEVER use ```text — it will NOT render as a diagram. Critical Rules Every diagram starts with @startuml and ends with @enduml Use left to right direction for process flows (start→end reads left-to-right) Use mxgraph.bpmn.* for BPMN events, gateways, and task markers Use mxgraph.eip.* for Enterprise Integration Pattern icons Use mxgraph.lean_mapping.* for Value Stream Mapping symbols Default colors are applied automatically — you do NOT need to specify fillColor or strokeColor Use rectangle "Pool" { ... } for BPMN pools and lanes Sequence flows use --> , message flows use ..> (dashed) Full stencil reference: See stencils/README.md for 9500+ available icons.
