Goal
Post-launch, bring the frontend's major dependencies up to current majors. Each upgrade below must be landed with the frontend gate (Biome + tsc + Vitest) and the C1 Playwright e2e re-validated green, and the real /screen demo driven in a browser on localhost (secure context — required for WebCrypto signature verify + OPFS).
Upgrades
- React 18 → 19 — bump
react and react-dom to 19, and @types/react / @types/react-dom to 19. Review the 19 migration notes (ref-as-prop, removed legacy APIs, act changes) for the app and the @amlfilter/browser package.
- React Router 6 → 7 — breaking: the ~8
<Route element={...}> definitions in frontend/app/src/App.tsx need rewriting to the v7 routing API. Verify every route (notably /screen and the admin routes) still resolves and renders after the migration.
- Vite → latest major — re-check the build config, the es-target (the demo previously crashed on an es2020 model-load regression, so validate the in-tab MiniLM load specifically), and the dev-server/preview flow.
- Vitest → latest major — align with the Vite bump; re-run the parity tests (
crypto.test.ts, normalize.test.ts, scoring.parity.test.ts).
- TypeScript → latest — fix any new strict-mode diagnostics; keep
no any / no default exports.
Validation per upgrade (non-negotiable)
For each PR:
pnpm -r run build + pnpm -r run lint green.tsc clean, Vitest green (incl. the Python↔TS scoring parity golden).- C1 Playwright e2e (
frontend/app → pnpm test:e2e:c1) green — and it must cover the real committed demo bundle (backend/examples/catalog) against the pinned frontend/app/public/public.key, not just a synthetic test catalog.
- Drive
/screen in a real browser on http://localhost:<port>: boot, type a query (e.g. Ivan Fakovich), read the rendered dossier, confirm a clean console.
Prefer landing these as separate PRs (one major per PR) so a regression is easy to bisect; React + React Router may need to land together if their type/runtime contracts interlock.
Note: dependencies label was requested but does not exist in this repo; applied enhancement only.
