Sanitize external URL in Angular

To sanitize a URL in Angular, you can use the DomSanitizer service. The DomSanitizer service has a method called sanitize that takes two parameters: the security context and the value to be sanitized. The security context specifies the type of value that you are trying to sanitize. For a URL, the security context should be SecurityContext.URL.

The following code shows how to sanitize a URL in Angular:

Code snippet

import { DomSanitizer } from '@angular/platform-browser';

export class AppComponent {
  constructor(private sanitizer: DomSanitizer) {}

  get sanitizedUrl() {
    return this.sanitizer.sanitize(SecurityContext.URL, 'https://www.webopixel.com');
  }
}

The sanitizedUrl property will contain the sanitized URL. The sanitized URL will be a safe URL that cannot be used to exploit security vulnerabilities.

Here are some things to keep in mind when sanitizing URLs in Angular:

  • You should only sanitize URLs that come from untrusted sources.
  • You should not sanitize URLs that you trust, such as the URL of your own website.
  • You should not sanitize URLs that contain sensitive information, such as user passwords.

If you are not sure whether a URL is safe, you should not sanitize it.
