5 cool usages of inject function in Angular - Lightning talk
summary
Title claims five concrete patterns using Angular 14+ inject with code that actually runs: a short, working useOnDestroy helper that auto-completes observable streams; replacements for decorators with useHostBinding and a host-listener approach that can run outside zone for fewer change detection cycles; composable utilities that interoperate; and a more complex useOnChanges that turns input changes into a switchMap-able stream. The uploader includes a small homework set including a useHttpResource sketch.
