TypeScript 7 is the Go-native rewrite of tsc, ~10x faster but only
distributed as @typescript/native-preview daily builds at the time
of writing (npm typescript@latest is still 6.0.3). Add it as a
non-disruptive type-check tool: yarn typecheck → tsgo --noEmit.
Vite still uses esbuild for transpilation, ESLint still uses TS 6
through @typescript-eslint v8, IDEs continue using their bundled TS.
This commit only adds a type-check tool — nothing replaces.
Required tsconfig.json adjustments for TS 7 compatibility (still
valid for TS 6):
- Drop baseUrl: "./src" (removed in TS 7). The codebase has no
bare/non-relative imports that depended on it; all imports are
relative or aliased.
- Drop downlevelIteration: true (removed in TS 7; target es2022
doesn't need it).
- moduleResolution: "node" → "bundler" (TS 7 dropped node10; bundler
is the right mode for Vite anyway).
- paths "@layout/*" entries now use leading "./" (TS 7 disallows
non-relative path mappings). Add "@/*" → "./src/*" to match the
Vite alias used in some components.
Other TS 7 adjustments:
- src/react-app-env.d.ts: add module declarations for *.css/.scss/.sass
side-effect imports (TS 7 with bundler resolution requires them) +
Window.NitroConfig / Window.NitroSecureApiUrl globals which were
used in App.tsx without a declaration.
- src/common/Popover.tsx: explicit `import { JSX } from 'react'`
because TS 7 dropped the implicit global JSX namespace.
Verification:
- yarn eslint still passes (TS 6 / @typescript-eslint v8 happy with
the migrated config).
- yarn typecheck (tsgo) runs and reports only cascading errors
rooted in the missing @nitrots/nitro-renderer sibling repo
(environmental, not introduced here).

Run eslint --fix across src/ to clear ~1900 mechanical lint errors
surfaced by the @typescript-eslint v8 + react-hooks v7 + react-compiler
upgrade in the React 19 modernization PR.
Issues fixed automatically:
- brace-style (Allman): try/catch one-liners reformatted to multi-line
- indent: tab-vs-space and depth corrections
- semi: missing trailing semicolons
- no-trailing-spaces
No semantic changes. Remaining 701 errors are real-code issues
(set-state-in-effect, rules-of-hooks, no-unsafe-* type checks) that
need manual per-file review.

Adopt React 19 idioms across the codebase. The runtime was already on
react@19.2.5 but no React 19 APIs were in use.
- forwardRef -> ref-as-prop in 7 layout/component files
(NitroInput/Button/ItemCountBadge/Card×5/InfiniteGridItem,
ToolbarItemView, AvatarEditorIcon)
- <Ctx.Provider> -> <Ctx> in 6 contexts (CatalogAdmin, FloorplanEditor,
UiSettings, GridContext, NitroCardContext, NitroCardAccordionContext)
- Native <script> hoisting for Turnstile, ExternalPluginLoader, GoogleAdsView
(React 19 dedupes by src; removes manual document.head.appendChild +
module-level promise caches)
- React Compiler enabled at build time via babel-plugin-react-compiler
in vite.config.mjs (target: '19'), plus eslint-plugin-react-compiler
in lint mode
- Global <ErrorBoundary> + <Suspense> in src/index.tsx using
react-error-boundary, with LoadingView as fallback
- BackgroundsView migrated to use(promise) as a demonstrator pattern
for Suspense-driven config loading
- ESLint react setting bumped 18.3.1 -> 19.2; legacy
@typescript-eslint/ban-types replaced with no-restricted-types
(the old rule was removed in @typescript-eslint v8)
- Refresh public/configuration/{asset-loader,bootstrap}.js to match
current write-asset-loader.mjs output
Phase 3 (login forms -> useActionState/useFormStatus) deferred:
LoginView is 1623 lines with lockout + Turnstile + heartbeat
interleaving; safer as its own PR.
