ng-diagram 1.2.3

v1.2.3 - Z-Ordering Rework & Measurement API

on Node.js NPM

✨ Added

• invalidateMeasurements(options?) method on NgDiagramService - forces re-measurement of nodes, ports, and edge labels via ResizeObserver. Call with no arguments to re-measure the entire diagram, or pass { nodes: [...], edges: [...] } to target specific elements. Invalidating a node also re-measures all its ports. Use this when CSS-only repositioning (class toggles, style bindings) changes port positions without changing sizes, which ResizeObserver cannot detect (#698)
• initialConnectedEdgesMap on MiddlewareContext - a Map<string, string[]> from node ID to connected edge IDs (source or target) captured before any modifications. Allows middleware to find edges connected to specific nodes without scanning all edges (#697)
• MCP server: inline code snippets - search_docs and get_doc now resolve <CodeSnippet> and <CodeViewer> tags in documentation pages, inlining the referenced source files directly into tool results. AI assistants see complete, runnable examples without needing access to the source repository (#699)

🧩 Changed

• Updated z-index defaults - selectedZIndex changed from 1000 to 10000 to provide more headroom for explicit zOrder values; temporaryEdgeZIndex changed from 1000 to 2147483647 (max 32-bit int) so the edge being drawn always renders on top (#697)

🐛 Fixed

• Z-ordering reworked - rewrote the z-index assignment middleware and bringToFront/sendToBack commands, fixing multiple issues: children are now always rendered above their parent group regardless of zOrder values, and siblings within a group are correctly re-sorted when zOrder, selection, or group membership changes.(#697)
• Fixed ports and edge labels not being measured when a node or edge is removed and re-added with the same ID in the same tick (#701)
