Signals Alongside RxJS

Setup & Components ✓Routing HTTP RxState & PerfShip & Projects

Routing HTTP Rx · 2 — Data · ~6 min · RxJS and Signals

What is this?

Signals Alongside RxJS practices reactivity with RxJS and/or signals.

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';
// Signals Alongside RxJS

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 Signals Alongside RxJS simply. You ran a small Angular demo. You know one pitfall.

Signals Alongside RxJS in AngularVerse

Your team applies signals alongside rxjs on an admin UI.

Outcome: A concrete next coding step exists.
