import { Component } from '@angular/core';
import { TextHighlighterService } from 'ngx-text-highlighter';

@Component({
  selector: 'app-your-component',
  template: `
    <div [innerHTML]="highlightedText"></div>
  `,
})
export class YourComponent {
  text: string = 'Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua.';
  highlightedText: string;

  constructor(private textHighlighterService: TextHighlighterService) { }

  highlight(searchText: string) {
    this.highlightedText = this.textHighlighterService.highlight(this.text, searchText);
  }
}
