Angular signalsintermediate
A signal is a value that tells the template when it changed, so Angular updates only what actually depends on it — and computed() derives from other signals rather than storing a second copy that can drift.
The React dashboard, in Angular: fetch on start, handle every state, derive the rest with signals.
It loads, it fails visibly, it filters without recomputing, and rows are tracked.
Published in full, before you start — every point is one of these and there is nothing else.

Standalone components declare what they need instead of belonging to an NgModule, and inject() gets a dependency without a constructor parameter — together they are most of what changed in modern Angular.
The @if and @for blocks replaced *ngIf and *ngFor, and the track expression is what stops Angular rebuilding every row when one of them changes.
Anything that talks to a network can be slow or fail; a screen with no loading state and no error state is a screen that looks broken the first time the wifi drops.
Every await can reject; modelling idle, loading, success and error explicitly is what stops a slow network showing a blank screen with no explanation.
