Why should you care?

Async UI needs a clear dataflow story.

See it live — copy this example

Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.

import { signal } from '@angular/core';
import { map } from 'rxjs/operators';
// switchMap for Search

What happened?

• Pick the right tool: signals for sync local state, RxJS for streams.
• Follow the steps below — typing the code yourself is the fastest way to learn.

Practice next

1. Reproduce the snippet in an Angular CLI app.
2. Change one binding or route and re-serve.
3. Note one mistake you almost made.
4. Extract a service.
5. Add a trivial unit test later.

Remember

You can explain switchMap for Search simply. You ran a small Angular demo. You know one pitfall.

switchMap for Search in AngularVerse

Your team applies switchmap for search on an admin UI.

Outcome: A concrete next coding step exists.
