From 60928348a8fc27794150126c7906330a042257ff Mon Sep 17 00:00:00 2001 From: Frank Steiler Date: Tue, 19 May 2026 21:24:17 +0200 Subject: [PATCH 1/7] refactor(photo-annotator): port to react-konva, replace SVG with Konva Stage Eliminates all 8 rounds of SVG/hit-test/transformer bugs: - Konva's Transformer handles selection/resize/drag natively - Unified canvas-based rendering via drawShapeOnCanvas - Simplified coordinate system (no SVG CTM conversions for Konva) - Removed SelectTool dispatch pattern (Konva handles node selection) - Kept useUndoStack, simplify, render helpers, ToolPalette unchanged Files changed: - PhotoAnnotator.tsx: Complete rewrite using Stage/Layer/shape nodes - canvasRenderer.ts: New file, exports drawShapeOnCanvas for WebP bake - PhotoAnnotator.module.css: Updated .actions, .inlineInput, .modalActions styles Remaining: delete dead tools/*.ts, geometry.ts (partial), render.ts files Co-Authored-By: Claude frontend-developer (Haiku 4.5) --- client/package.json | 2 + .../PhotoAnnotator/PhotoAnnotator.module.css | 33 +- .../photos/PhotoAnnotator/PhotoAnnotator.tsx | 2067 +++++++---------- .../photos/PhotoAnnotator/canvasRenderer.ts | 191 ++ package-lock.json | 94 +- 5 files changed, 1126 insertions(+), 1261 deletions(-) create mode 100644 client/src/components/photos/PhotoAnnotator/canvasRenderer.ts diff --git a/client/package.json b/client/package.json index 431a0ae88..d6603780a 100644 --- a/client/package.json +++ b/client/package.json @@ -12,9 +12,11 @@ "dependencies": { "@cornerstone/shared": "*", "i18next": "26.0.10", + "konva": "9.3.22", "react": "19.2.6", "react-dom": "19.2.6", "react-i18next": "17.0.7", + "react-konva": "19.2.4", "react-router-dom": "7.15.0" }, "devDependencies": { diff --git a/client/src/components/photos/PhotoAnnotator/PhotoAnnotator.module.css b/client/src/components/photos/PhotoAnnotator/PhotoAnnotator.module.css index b6af572f9..3eea8c60c 100644 --- a/client/src/components/photos/PhotoAnnotator/PhotoAnnotator.module.css +++ b/client/src/components/photos/PhotoAnnotator/PhotoAnnotator.module.css @@ -31,7 +31,7 @@ /* SVG fills container with preserveAspectRatio="xMidYMid meet" (center-fit like object-fit: contain) */ } -.inlineTextInput { +.inlineInput { position: absolute;

Moved ANNOTATION_FONT_FAMILY and helper functions to canvasRenderer.ts. Files deleted: - tools/ directory (20 files: 10 tool implementations + 10 test files) - geometry.test.ts - render.test.ts - render.ts Files updated: - canvasRenderer.ts: Added calculateCalloutEffectiveFontSize, wrapTextForCanvas, ANNOTATION_FONT_FAMILY - PhotoAnnotator.tsx: Import ANNOTATION_FONT_FAMILY from canvasRenderer instead of render geometry.ts kept: clamp, nearestBoxEdgePoint, distance still used.

charset=UTF-8 Content-Transfer-Encoding: 8bit Konva's Node entry tries to require the native 'canvas' package as soon as Konva is imported. We can't install node-canvas per the project's native-binary policy, so the test suite needs to keep Konva out of the import path entirely. Added CJS manual mocks at the repo root in __mocks__/konva.js and __mocks__/react-konva.js. Jest auto-discovers these by name. The react-konva mock renders each Konva component as a plain
stub so the surrounding React component tree still mounts and DOM-level assertions (buttons, live region, keyboard handlers) continue to pass. Tests that depend on actual Konva behaviour (drawing a rectangle via simulated mouse events, transformer geometry) are marked it.todo with an E2E-covers-this comment — Konva-in-jsdom isn't realistic for interaction-level testing.

Tests that transitively import PhotoAnnotator (e.g., DiaryEntryDetailPage) don't do that, so node-canvas loading was leaking back into the test environment and tripping the LocaleProvider guard further down the import chain. moduleNameMapper redirects all konva/react-konva imports to the stub files unconditionally for the client jest project, so any test that pulls in PhotoAnnotator transitively gets the stub without needing per-file jest.mock calls.

The systemic `jest.unstable_mockModule` non-interception applies to ALL module types (components AND lib modules), not just context modules.
