Framework inputs move through provider-configured pipelines rather than a single application backend. Bootstrap configuration produces injectors and component instances; navigation produces resolved route data and rendered views. HTTP requests become interceptor chains and Fetch events, while documentation search transforms remote records into signal-owned UI state and browser persistence. The service worker owns separate version-assignment and cache-backed state.
- Root component and ApplicationConfig inputs become browser appProviders and platformProviders, then an EnvironmentNgModuleRefAdapter whose injector is passed to bootstrap.
- Signal getters call producerAccessed to track reads; changed writes update node.value, increment node.version and the producer epoch, and notify dependent consumers.
- Template text enters HtmlParser with source-mapping options; i18n metadata is processed before whitespace removal so message IDs retain their expected source relationship.
- navigateByUrl parses and merges a UrlTree, scheduleNavigation registers a pending task, and handleNavigationRequest receives current snapshots, navigation options, and promise completion callbacks.
- Documentation navigation metadata becomes route.data and a docContent resolver; that resolver injects DOCS_CONTENT_LOADER and passes contentPath to getContent.
- ContentLoader normalizes missing extensions to .md.html, fetches assets/content/{path} as text, produces {contents, id}, and caches the Promise by normalized path.
- DocsComponent receives resolved DocContent as an input; its template passes contents to DocViewer, whose effect renders HTML and installs client-side controls before emitting contentLoaded.
- HttpClient constructs HttpRequest and invokes the handler per subscription; HttpInterceptorHandler deduplicates interceptors, composes them in registration order, and removes its stability task through finalize.
- FetchBackend serializes request bodies and headers into RequestInit, reads response chunks, parses the requested body type, and emits either HttpResponse or HttpErrorResponse.
- SearchQuery drives a debounced resource; Algolia hits become SearchResultItem records, while history clicks copy those records into a signal-backed Map and serialize sorted items to localStorage.
- The service worker restores manifests, client assignments, and the latest version from its control table; CacheTable maps keys to requests and stores values as JSON responses.
