BPMN.js Differ

bpmn-js-differ is a semantic diffing utility specifically designed for comparing two BPMN 2.0 files programmatically. It analyzes the structural and semantic differences between two BPMN definitions, producing a detailed report of added, removed, changed, and layout-modified elements. The current stable version is 3.2.0. The library maintains a steady release cadence, often aligning with updates to its core dependencies like `bpmn-moddle` and `bpmn-js`. Its key differentiator lies in providing a structured, semantic diff output, which is crucial for building visual diff tools or automated change detection workflows for BPMN diagrams, as opposed to simple text-based comparisons.
