Move PrimeNG DataTable pagination, sorting, and filtering to the backend with lazy loading. This guide shows a complete Angular component example, the required LazyLoadEvent handling, backend contract expectations, and common mistakes like sort-order mismatch and missing totalRecords.
Learn how to implement NgRx Effects to handle asynchronous API calls, prevent race conditions with RxJS flattening operators, and avoid common stream termination errors.
Angular 17's signal inputs let components opt out of Zone.js change detection, updating only when their input signals actually change. This blog walks through the problem, the API, a worked counter example, trade-offs, and a quick way to verify the gains.
Learn how to enable lazy loading in PrimeNG’s p‑table so only the visible page of data is fetched from the backend, reducing initial load time and memory usage.
PrimeNG’s p‑Table can paginate data in‑browser or ask the server for each page via onLazyLoad. This post explains the decision factors, shows a minimal lazy‑loading example, lists pitfalls, and gives an actionable checklist.
Learn how NgRx’s createReducer enforces immutable state changes with a clear example, avoid common pitfalls, and understand when to use effects or EntityAdapter for more complex scenarios.
OnPush skips change detection unless an @Input reference changes, a template event fires, or the async pipe emits. Learn why mutating arrays in place causes stale views and how to use immutable updates to fix it.
A decision guide that compares NgRx Entity Adapter with hand‑written reducers, shows a compact trade‑off table, and provides a concrete implementation example with verification steps.
Learn how Angular's ChangeDetectionStrategy.OnPush cuts unnecessary change detection cycles by updating views only when input references change or events fire, with a concrete component example and common pitfalls.
