Extends the existing fetch-and-bypass-Content-Disposition pattern already used for text/markdown previews: the PDF's bytes are fetched into a Blob and handed to the browser's native viewer via a blob: URL, which carries no HTTP headers of its own. That sidesteps Content-Disposition: attachment the same way a script-initiated fetch() already does for text, without needing an <iframe>/<embed> to navigate to the real file URL directly (which would respect that header and force a download) -- and without the backend allowlist endpoint this issue's original scoping assumed would be necessary. MIME type is forced to application/pdf explicitly rather than trusted from the upload, since getPreviewKind gates on the .pdf extension alone (matching its existing behavior for .md/.txt), so a mislabeled file still renders instead of downloading or erroring. Object URLs are revoked on unmount/file-change to avoid leaking memory. Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
DS Chat frontend (Phase 1)
React + Vite PWA. Login, room list, and chat views wired to the backend's
REST API and /ws/chat WebSocket endpoint. See ../README.md
and ../backend/README.md for full local setup.
Dev
npm install
npm run dev
The dev server proxies /api and /ws to http://localhost:8000 (see
vite.config.ts), so the backend must be running for anything beyond the
login page to work.
Build
npm run build
Generates the PWA manifest and service worker via vite-plugin-pwa into dist/.
