* fix(web): sanitize rendered markdown through DOMPurify (TASK-647)
Comments (and any other caller of renderMarkdown) piped marked() output
straight to {@html}. A malicious comment could inject <script> / <img
onerror> / javascript: links that executed on every viewer's page —
stored XSS with full session takeover.
Wrap renderMarkdown's output in DOMPurify.sanitize with a strict
allowlist of markdown-produced tags and attributes. Also HTML-escape
the wiki-link title before interpolating it into the <a>/<span> so the
intermediate HTML is well-formed even for pathological titles.
Sanitization runs client-side only (adapter-static SPA mode has no
runtime SSR of user content). In SSR/prerender contexts we return ""
rather than emit unsanitized HTML — markdown-bearing views fetch their
data at runtime anyway, so the empty fallback is a no-op.
Parent: PLAN-643 (OSS Security Hardening).

Pad Web UI
SvelteKit 2 + Svelte 5 frontend for Pad, compiled to static files and embedded into the Go binary.
Development
npm install
npm run dev # Dev server at localhost:5173 (proxies API to localhost:7777)
npm run build # Production build to build/
npm run check # Type checking with svelte-check
When developing, run the Go backend separately with make dev from the project root.
Building for Production
Do not build in isolation. Always use make build from the project root — this builds the web frontend, then compiles the Go binary with the build output embedded via //go:embed.
Stack
- Svelte 5 with runes (
$state,$derived,$effect) - SvelteKit 2 with
adapter-static(SPA mode) - Tiptap block editor with markdown round-trip
- svelte-dnd-action for drag-and-drop in board/list views
- SSE for real-time updates
- TypeScript throughout
