Import and use

Import only what you need. ngxtension is built with tree-shaking in mind.

import { linkedQueryParam, paramToNumber } from 'ngxtension/linked-query-param';
import { derivedFrom } from 'ngxtension/derived-from';

@Component({
  template: `
    <input [(ngModel)]="searchQuery" />

    @for (result of results(); track result.id) {
      <div>{{ result.title }}</div>
    }

    <pagination [(page)]="pageNumber" />
  `,
})
export class MyComponent {
  readonly searchQuery = linkedQueryParam('search');
  readonly pageNumber = linkedQueryParam('page', {
    parse: paramToNumber({ defaultValue: 1 }),
  });

  readonly results = derivedFrom([this.searchQuery], pipe(
    switchMap((query) => this.searchService.search(query)),
  ));
}
