Marcel	ca5726e7c3	fix(frontend): zoom buttons now re-render immediately (#39 ) Some checks failed CI / Unit & Component Tests (pull_request) Successful in 4m42s Details CI / Backend Unit Tests (pull_request) Successful in 2m18s Details CI / E2E Tests (pull_request) Failing after 13m15s Details CI / Unit & Component Tests (push) Successful in 2m20s Details CI / Backend Unit Tests (push) Successful in 2m11s Details CI / E2E Tests (push) Failing after 13m25s Details scale was only read inside the async renderPage function, so Svelte 5 never tracked it as a reactive dependency of the effect. Reading scale synchronously in the effect condition registers it as a dependency and triggers a re-render on every zoom change.

Marcel	0ef81e20f6	devops: add rebuild-frontend.sh script Some checks are pending CI / Unit & Component Tests (push) Successful in 2m36s Details CI / Backend Unit Tests (push) Successful in 2m3s Details CI / E2E Tests (push) Has started running Details Stops the container, removes the stale node_modules volume, and rebuilds the image. Run this after adding or updating npm dependencies. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-23 22:39:53 +01:00
Marcel	1ad8fffd1b	fix(frontend): load pdfjs-dist dynamically to avoid SSR crash (#39 ) Static import of pdfjs-dist fails during SSR because DOMMatrix and other browser globals are unavailable in Node.js. Move the import into onMount so it only ever executes in the browser. A plain pdfjsLib variable holds the module; a $state boolean pdfjsReady triggers the load-document effect once the library is available.

Marcel	5fb6a1eec0	feat(frontend): replace iframe with PDF.js viewer (#39 ) - Install pdfjs-dist v5 and add optimizeDeps pre-bundle config - New PdfViewer.svelte component: renders each page on a <canvas> with correct device-pixel-ratio scaling, overlays a text layer (enables text selection; foundation for annotations in #40), prev/next navigation, zoom controls, and lazy page rendering (only current ±1 pre-fetched — avoids freezing on multi-page documents) - Replace the <iframe> in documents/[id]/+page.svelte with PdfViewer; image attachments continue to use <img>; detection now uses doc.contentType instead of filename extension - Unit tests for navigation controls and page counter (pdfjs mocked) - E2E tests: PDF renders as canvas (not iframe), nav controls visible, image fallback stays as <img>; minimal.pdf fixture for upload tests Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-23 19:10:02 +01:00
Marcel	4f69457a68	fix(dev): inject Authorization header from cookie in Vite dev proxy Some checks failed CI / Unit & Component Tests (pull_request) Successful in 2m13s Details CI / Backend Unit Tests (pull_request) Successful in 2m9s Details CI / E2E Tests (pull_request) Successful in 20m15s Details CI / Unit & Component Tests (push) Successful in 2m4s Details CI / Backend Unit Tests (push) Successful in 2m8s Details CI / E2E Tests (push) Failing after 23s Details Browser-side fetch('/api/...') calls bypass SvelteKit's handleFetch hook (which adds the Authorization header from the auth_token cookie for SSR). As a result, client-side API calls in the dev server always got a 401. Add a proxy configure hook that extracts the auth_token cookie from incoming requests and sets it as the Authorization header before forwarding to the backend. This makes browser-side fetches (history panel, file preview, etc.) work correctly in dev mode. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-23 17:05:20 +01:00

Also wait for versions to load (API call) before asserting on version items or the compare button. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>	2026-03-23 16:03:37 +01:00
