Why should you care?

Enterprise lists feel slow without OnPush, trackBy, and budgets.

See it live — copy this example

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

changeDetection: ChangeDetectionStrategy.OnPush
// CDK Overlay and A11y Notes

What happened?

• Measure first; apply the smallest performance win that fits.
• 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 CDK Overlay and A11y Notes simply. You ran a small Angular demo. You know one pitfall.

CDK Overlay and A11y Notes in AngularVerse

Your team applies cdk overlay and a11y notes on an admin UI.

Outcome: A concrete next coding step exists.
