Admin Toolbar

Frontend staff toolbar for Ghost sites. Uses Preact (~3KB) instead of React (~40KB) since this is a lightweight public-facing widget that only needs basic rendering and hooks — the same rationale applies to any future small public scripts where bundle size matters more than ecosystem compatibility.

Development

pnpm build    # one-off build
pnpm dev      # build + preview with watch (started automatically by pnpm dev from root)
pnpm test     # build + run tests against UMD bundle

How it's served

In production, the script is loaded from jsDelivr via the adminToolbar config in defaults.json, following the same CDN pattern as portal, comments-ui, and the other public apps. In development, the Docker Dockerfile overrides the URL to proxy through Caddy to the local vite preview server on port 4176.
