Every plugin iframe loaded /plugin-sandbox, a force-dynamic Next page.
Each frame then fetched, parsed and hydrated Next's client router on top
of React and the runtime, and the server rendered the page once per
frame, one after another when a dozen plugins started together.
Sandboxed frames have opaque origins, so the browser's code cache never
helps, and they run on the host page's main thread: with 12 plugins
the frames took 2.5-3 s to come up after the app had loaded.
The sandbox routes now return a small HTML page with the UI kit's
stylesheet and the runtime as an ES module, both built ahead of time:
- `scripts/build-plugin-sandbox.mjs` bundles the runtime with esbuild
and compiles `plugin-kit.css` with the app's Tailwind setup into
`public/plugin-sandbox-assets/`, with a manifest. Named Tabler imports
are pointed at the icons' own files, so the full icon set stays in a
chunk that only loads for an icon name the kit doesn't ship.
- `npm run build`, `npm run dev`, the Dockerfile and the perf-guard
workflow run it before `next build`.
- `lib/plugin-sandbox/sandbox-document.ts` writes the page; proxy.ts
still sets the sandbox CSP and the script carries its nonce.
- The assets are served from public/ with CORS and immutable caching.
A frame on an idle page is ready in 255 ms instead of 362 ms, eleven at
once in 1.0 s instead of 2.1 s.
The old panel kept its active tab in a store, so every page sat at
/admin, the sidebar duplicated the webmail rail by hand, and each page
was a stack of boxed cards with their own save buttons. Plugin settings
were only reachable through a gear icon in a row of five.
- one catch-all route for the whole panel; pages switch through
history.pushState, so `/admin/plugins/<id>`, the back button, bookmarks
and connector links all work without a route transition
- sidebar laid out like the user settings: back to mail, search over
pages and their sections, two group headings, change password and
sign out at the bottom; the phone shows a list, then the page
- pages use SettingsSection rows instead of nested cards, with one page
header, one flash message and one save bar at the bottom (Discard,
Save, Ctrl+S); the unsaved-changes prompt still guards leaving
- plugins and themes are lists of rows with a toggle each; a row opens
the extension's own page with its settings, force-on, permissions,
kept versions and removal
- overview shows stat tiles, server facts and recent activity
- old `/admin?tab=x` links redirect; the tab store is gone and the
connector registry resolves admin links to the page URL
- `NEXT_TURBOPACK_ROOT` overrides the Turbopack root so `next dev` runs
from a worktree with a junctioned node_modules
The standalone trace excluded only `repos/`. It follows the runtime's
file reads, so building from a checkout that had been run copied
`data/` (admin password hash, plugin signing key, audit log, synced
settings), `local-data/` and `.env` files into `.next/standalone`, and
the Docker build context did not exclude `data/` or `local-data/`
either. Both now leave them out.
