Pipes Built-in and Custom is a core UI building block: components, templates, DI, or pipes.
Why should you care?
Almost every screen is a composition of these fundamentals.
See it live — copy this example
Run examples in an Angular CLI project (ng serve). Prefer standalone components and TypeScript strict mode.
@Component({
standalone: true,
selector: 'app-demo',
template: `<!-- Pipes Built-in and Custom -->`,
})
export class DemoComponent {}
What happened?
- Start from a standalone component and add only what the topic needs.
- Follow the steps below — typing the code yourself is the fastest way to learn.
Practice next
- Reproduce the snippet in an Angular CLI app.
- Change one binding or route and re-serve.
- Note one mistake you almost made.
- Extract a service.
- Add a trivial unit test later.
Remember
You can explain Pipes Built-in and Custom simply. You ran a small Angular demo. You know one pitfall.
