Root cause: Dockerfile copied only browser/ to nginx; server/server.mjs
was built but never deployed or executed. Prerender baked DEFAULT_CONFIG
into static HTML with no API at build time, causing stale content on
every initial paint.
Changes:
- Dockerfile: serve stage uses node:22-alpine, installs nginx via apk,
copies both browser/ and server/ bundles from build stage
- docker-entrypoint.sh: starts Angular SSR Node process on port 4200,
waits for readiness, exports SSR_API_BASE_URL, then exec nginx
- nginx.conf.template: adds upstream ssr_backend block (127.0.0.1:4200),
proxies / to SSR backend, static assets served directly with 1y cache
- app.server.routes.ts: all routes switched from RenderMode.Prerender
to RenderMode.Server for zero stale content
- server.ts: removed dead prerender code (PRERENDERED_ROUTES,
isPrerenderedRoute, allowStaticRouteRender)
- main.server.ts: injects SSR-aware apiBaseUrl via APP_CONFIG
(reads SSR_API_BASE_URL env var)
- server.spec.ts: updated 5 test suites + added 5 new suites (31 tests)
covering server.ts cleanup, RenderMode.Server, entrypoint lifecycle,
Dockerfile build, nginx upstream proxy, and API URL injection
- vitest.config.ts: added server.spec.ts to include pattern
Request flow: Browser -> nginx (port 80) -> SSR server (port 4200)
-> Angular SSR -> HttpClient -> localhost:80/api/station-config
-> nginx proxies to api:8000 -> fresh data rendered in HTML
- ThemeService: remove isPlatformBrowser guard so CSS custom properties
are applied during SSR/prerender — server-rendered HTML now carries the
correct color scheme and gradients (fixes missing colors on test site).
- main.ts: add provideClientHydration() so Angular preserves the server-
rendered DOM on the client instead of destroying and rebuilding it
(fixes jarring full-page reload between static and dynamic versions).
- Tests: update theme.service.spec.ts to match new behaviour, expand
coverage with gradient tests and empty-value handling (9 tests).
Fix structured-data.component.spec.ts import paths. All 54 tests pass.
