NestJS now serves the whole surface: every /api domain plus the platform
routes (uploads, /mcp, the OAuth/MCP SDK + /.well-known metadata and the
production SPA fallback). Removed server/src/app.ts, all of
server/src/routes/* and the strangler dispatcher; index.ts and the
integration suite share a single buildApp() bootstrap so prod and tests
can't drift.
- Platform/transport routes extracted to nest/platform/platform.routes.ts
and mounted before app.init() — Nest's router answers an unmatched
request with a 404, so a route registered after init is never reached.
The SPA fallback is a NotFoundException filter and the catch-all uses a
RegExp (Express 5's path-to-regexp rejects a bare '*').
- New modules: memories (/api/integrations/memories — the Journey
gallery's Immich/Synology proxy), addons (GET /api/addons) and the
cross-trip GET /api/reservations/upcoming.
- TrekExceptionFilter reproduces the old multer / err.statusCode handling
so upload rejections keep their 400/413 { error } body and non-ASCII
filenames survive (defParamCharset).
- addTripToJourney and the MCP get_journey_share_link tool gained the
trip-access check they were missing.
- Re-pointed the 34 integration tests + the websocket test onto the Nest
app; removed the now-meaningless Express-vs-Nest parity tests and a few
orphaned client components.
Brownfield strangler migration of the backend onto NestJS modules
(auth, trips, days, places, assignments, packing, todo, budget,
reservations, collab, files, photos, journey, share, settings, backup,
oidc, oauth, admin, atlas, vacay, weather, airports, maps, categories,
tags, notifications, system-notices) served through a per-prefix
dispatcher, keeping the existing SQLite/better-sqlite3 DB and JWT
httpOnly cookie auth, with behavioural parity for every route.
Client: React 19 upgrade, "page = wiring container + data hook"
pattern across all pages, per-domain Zustand stores bound to
@trek/shared contracts, and decomposition of the large components
(DayPlanSidebar, PackingListPanel, CollabNotes, FileManager,
MemoriesPanel, PlacesSidebar, CollabChat, SystemNoticeModal,
BudgetPanel, PlaceFormModal, ...) into focused render units backed by
in-file hooks.
Apply the shared global request pipeline (helmet/CSP, CORS, HSTS,
forced HTTPS, the global MFA policy and request logging) to the NestJS
instance as well, so a migrated route is protected identically to the
legacy fallback rather than bypassing it.
First strangler migration (L1): /api/weather is served by a NestJS module.
- @trek/shared/weather Zod contract; Nest controller byte-identical to the legacy Express route (paths, query params, status codes, { error } bodies, lang default, ApiError/500 passthrough). Service reuses getWeather/getDetailedWeather (+ shared cache; MCP tools unchanged).
- Strangler routes /api/weather to Nest by default; the legacy Express route + its migration-time parity test were decommissioned in this PR.
- Frontend (FE2): weatherApi typed against the @trek/shared WeatherResult contract.
- Harness: reusable Nest-vs-Express parity harness, e2e harness (temp SQLite + seed/cookie helpers, real JwtAuthGuard), src/nest coverage gate raised to >=80%, src/nest test guide.
- Verified end-to-end on a prod mirror (dev1): 401/400/200 via Nest with real Open-Meteo data, Express route gone.
