Angular 17–20: standalone components, Signals, OnPush, RxJS, performance.
6 posts · 0 questions
30 senior Angular interview questions with deep answers and real code: change detection, OnPush, RxJS operators, signals, and performance.
OnPush, trackBy, lazy loading, Signals, and standalone components — the Angular 19 performance playbook with real production metrics from Mattrx.
Webpack Module Federation vs Native Federation, independent deployments, versioning shared deps — the Angular micro frontends playbook from Mattrx.
Signals model state, RxJS models events over time — when to use each, performance numbers, and the interop pattern that uses both at the right boundary.
Core, Shared, Feature modules + Nx monorepo — the enterprise Angular layout that survives 4 apps, 20 libs, 5 teams. Real project + production metrics.
NgRx (classic + ComponentStore + SignalStore), Signals, NGXS, Akita — same Mattrx feature implemented every way with bundle, LOC, and DevTools tradeoffs.
