Each route page now renders <SeoHead> with title, description,
canonical, hreflang, OG, and Twitter card from the SEO builders.
Search pages render <JsonLdRenderer> with ItemList of Flight
schemas. Details page renders Flight JSON-LD. Barrel exports
updated with 2F SEO and JSON-LD functions.
TDD-driven schema.org JSON-LD builders using schema-dts types.
buildFlightJsonLd maps ISimpleFlight to Flight schema with
airports, times, and provider. buildFlightListJsonLd wraps
search results as an ItemList of ListItems.
SEO builder pure functions for all 6 Online Board route types,
each returning SeoHeadProps with title, description, canonical,
hreflang, OG, and Twitter card. Populated empty EN locale SEO
keys with English translations matching the Russian pattern.
Start page, flight/departure/arrival/route search pages,
and flight details page. Each route is thin: parses URL
params, lazy-loads the feature component with Suspense.
OnlineBoardSearchPage (shared by all 4 search routes),
OnlineBoardStartPage (search form landing), and
OnlineBoardDetailsPage (flight detail view with legs).
All wired to existing hooks from 2C/2D. 21 tests passing.
Two thin composition hooks that connect the generic SignalR hook (1E)
to board-specific channels: useLiveBoardSearch for search pages
(SubscribeDate channel) and useLiveFlightDetails for the details page
(Subscribe channel). Both are SSR-safe and client-only.
Pure API functions (searchFlights, getFlightDetails, getCalendarDays)
with dependency-injected ApiClient, plus three thin React hooks
(useOnlineBoard, useFlightDetails, useCalendarDays) for search,
details, and calendar pages. 17 TDD tests for API layer covering
URL construction, response mapping, and error handling.
Pure TypeScript port of Angular OnlineBoardUrlBuilder/Parser covering
all 6 URL types (start, flight, departure, arrival, route, details).
Includes roundtrip parity tests and edge cases for suffixed flights,
variable-length flight numbers, time ranges, and 3-char carriers.
StationDisplay, TimeGroup, FlightStatus, DurationDisplay compose into
FlightCard; FlightList renders a list of cards with skeleton loading.
All components are props-driven with no data fetching.
Port Angular flight types (ISimpleFlight, IFlightLeg, ITimesSet, etc.)
to minimal React-friendly interfaces. Add formatDuration/formatTime/
formatDate/isDayChange as pure functions. Stub useCityName hook as
passthrough pending customer dictionary API endpoint.
Use proper type-safe interfaces instead of Node.js http types for the
health handler, and avoid vi.spyOn type issues in shutdown tests by
directly intercepting process.on.
healthMiddleware returns 200 if upstream was reachable within 60s, 503 otherwise.
Exports a factory function — registration in modern.config.ts is a future step.
Reference-counted connection management with grace period,
dynamic import to keep @microsoft/signalr out of SSR bundle,
and singleton sharing via getSharedConnection.
Root layout wraps children with LoggerProvider, ApiClientProvider, and
ErrorBoundary. Locale layout validates lang param against 9 supported
languages and provides a request-scoped I18nProvider.
