URL.origin

The origin read-only property of the URL interface returns a USVString containing the Unicode serialization of the origin of the represented URL.

The exact structure varies depending on the type of URL:

  • For http or https URLs, the scheme followed by '://', followed by the domain, followed by ':', followed by the port (the default port, 80 and 443 respectively, if explicitly specified).
  • For file: URLs, the value is browser dependant.
  • for blob: URLs, the origin of the URL following blob: will be used, e.g "blob:https://mozilla.org" will be returned as "https://mozilla.org".

Note: This feature is available in Web Workers

Value

A USVString.

Examples

const url = new URL("blob:https://mozilla.org:443/")
console.log(url.origin); // Logs 'https://mozilla.org'
