Architecture guide for using PrimeNG p-table with lazy loading to display >10k rows in Angular while meeting load‑time and memory constraints.
If your Angular app needs to show large lists, a plain *ngFor can choke the UI. PrimeNG’s VirtualScroller keeps the DOM tiny by only rendering visible rows. Learn how to set it up, what limits to watch, and how to verify it works.
Replace manual destroy$ Subjects with Angular's takeUntilDestroyed operator for declarative, injection‑context aware subscription cleanup.
Learn how Protractor’s WebDriverJS base and Angular zone synchronization work, where the key architectural boundaries lie, and how to mitigate common flakiness in Angular end‑to‑end tests.
Decide between global @ngrx/store and lightweight @ngrx/component-store by comparing scope, boilerplate, lifecycle, and debugging. This guide shows constraints, a comparison table, trade‑offs, and a validation approach to pick the right store.
Angular Signals replace zone.js change detection with fine-grained reactivity. This guide shows a practical service pattern, RxJS interop, signal-based inputs/outputs, and the five most common mistakes with verification steps.
Choosing the right RxJS operator for a live search box: cancel stale requests with switchMap, handle errors inside the inner stream, and clean up with takeUntil. Learn the semantics, trade‑offs, and a concrete Angular example.
Diagnostic guide for Angular's NG0100 ExpressionChangedAfterItHasBeenCheckedError: recognize the dev‑only symptom, trace mid‑cycle state writes, apply the fix matched to the cause, and know when to escalate to a data‑flow redesign.
An architecture note on using @ngrx/entity's createEntityAdapter for normalized collection state: requirements, minimal reducer and selector setup, server-data trust boundaries, tests, and the conditions that outgrow it.
