Trusted video URL, which causes Angular to allow binding into <iframe src>

Trusted video URL in iFrame in angular. Trusted video URL in iFrame in angular.

In Angular, when embedding a video URL inside an <iframe> using property binding ([src]), Angular's DomSanitizer is required to mark the URL as trusted. Otherwise, Angular blocks the binding due to security concerns.

Solution: Using DomSanitizer to Sanitize the Video URL

You can use Angular's DomSanitizer to bypass security restrictions safely.

Steps:

1. Import DomSanitizer in your component.
2. Sanitize the URL using bypassSecurityTrustResourceUrl().
3. Bind the sanitized URL in the template.

Example:

import { Component } from '@angular/core';
import { DomSanitizer, SafeResourceUrl } from '@angular/platform-browser';

@Component({
  selector: 'app-video',
  template: `
    <iframe [src]="trustedVideoUrl" width="600" height="400"></iframe>
  `
})
export class VideoComponent {
  videoUrl: string = "https://www.youtube.com/embed/dQw4w9WgXcQ"; // Example video
  trustedVideoUrl: SafeResourceUrl;

  constructor(private sanitizer: DomSanitizer) {
    this.trustedVideoUrl = this.sanitizer.bypassSecurityTrustResourceUrl(this.videoUrl);
  }
}
        

Explanation:

• DomSanitizer ensures that the URL is marked as trusted and avoids Angular’s security restrictions.
• bypassSecurityTrustResourceUrl() tells Angular that the URL is safe to use inside the iframe.

This approach ensures that Angular allows the video URL binding inside the <iframe> securely.
