Learn how Angular Signals provide synchronous, fine‑grained reactivity for local component state, eliminating the need for ChangeDetectorRef and Zone.js in many cases.
Signals, RxJS services, or NgRx SignalStore? A constraint-first comparison for Angular 17+, with a working cart store example and a bundle-and-profile verification checklist.
SolidJS compiles JSX to direct DOM updates wired to signals. Components run once, and only the specific DOM nodes that depend on a changed signal update, avoiding virtual DOM reconciliation.
SolidJS eliminates the Virtual DOM by using signals and memos for fine‑grained reactivity. Learn how to create targeted DOM updates, avoid common pitfalls like destructuring props, and verify your component’s behavior in the browser’s Elements tab.
Learn how NgRx SignalStore reduces boilerplate for local Angular state while keeping updates explicit, with a practical shopping‑cart example and guidance on when to use it.
SolidJS replaces virtual DOM diffing with fine-grained reactivity: signals track their own readers, effects and memos subscribe automatically, and control flow updates only the DOM nodes that change. A worked example shows a filterable list updating surgically — no dependency arrays, no useMemo.
Learn how SolidJS signals update only the changed DOM nodes, avoiding virtual‑DOM overhead, and see a concrete counter example plus trade‑offs.
Decide between NgRx Classic and the new SignalStore for your next Angular project. This guide compares boilerplate, type safety, async handling, and testing, then walks through a concrete Todo feature implementation in both APIs.
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.
