Lesson 10.8 of the Angular tutorial — debugging hydration mismatches: what each NG0500-range error means, a step-by-step routine, the usual culprits (random values, browser-only APIs, invalid HTML nesting, DOM manipulation, stripped whitespace), when ngSkipHydration is justified, and the Angular DevTools hydration overlay.

Lesson 10.4 of the Angular tutorial — why HttpClient requests fire twice: cold Observables with multiple subscribers, effects that re-run, SSR without the HTTP transfer cache, retry loops and CORS preflights, plus a Network-panel routine to tell them apart.

Lesson 9.7 of the Angular tutorial — caching rendered pages and assets with Cache-Control, keeping personal data out of shared caches, running on edge runtimes with AngularAppEngine, Node and serverless hosting with cold starts, and tactics for a lower time to first byte.

Lesson 9.6 of the Angular tutorial — how the HttpClient transfer cache avoids double fetches after SSR, its default rules, withHttpTransferCacheOptions and per-request transferCache, origin mapping, resource() with id, manual TransferState with makeStateKey, and keeping the payload small.

Lesson 9.5 of the Angular tutorial — how incremental hydration keeps server-rendered @defer blocks dehydrated until a hydrate trigger fires, every hydrate trigger, placeholders and client-side navigation, nesting rules, event replay, and which sections are worth deferring.

Lesson 9.4 of the Angular tutorial — the gap between visible and interactive on SSR pages, how event replay captures and replays early clicks, how it is enabled by default in v22, what it does and does not replay, writing replay-tolerant handlers, and shrinking the gap.

Lesson 9.3 of the Angular tutorial — how non-destructive hydration with provideClientHydration() reuses server DOM, how to verify it, the patterns that break it (direct DOM manipulation, invalid HTML nesting, platform-dependent templates, altered HTML), and when ngSkipHydration is justified.

Lesson 9.2 of the Angular tutorial — what provideServerRendering() and withRoutes() configure, main.server.ts and BootstrapContext, server.ts with AngularNodeAppEngine, the lifecycle of a server-rendered request, the REQUEST, RESPONSE_INIT and REQUEST_CONTEXT tokens, and keeping browser-only code off the server.

Lesson 9.1 of the Angular tutorial — the three render modes (Server, Prerender, Client), assigning them per route with ServerRoute[] in app.routes.server.ts, prerendering parameterised routes with getPrerenderParams and fallbacks, static output, and a decision tree for every route.
