If you want to efficiently retrieve and display data, consider creating a custom pipe. This pipe can store the results for future use, ensuring that the same value is returned when passing the same argument:
To implement this, create a file named safe-html.pipe.ts:
import { Pipe, PipeTransform } from '@angular/core';
import { DomSanitizer, SafeHtml } from '@angular/platform-browser';
@Pipe({ name: 'safeHtml' })
export class SafeHtmlPipe implements PipeTransform {
constructor(private sanitizer: DomSanitizer) {}
public transform(value: string): SafeHtml {
return this.sanitizer.bypassSecurityTrustHtml(value);
}
}
Once the pipe has been implemented, use it in your code like this:
<img [src]="image | safeHtml" />
