URL.origin

The origin read-only property of the URL interface returns a string 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 dependent.
• for blob: URLs, the origin of the URL following blob: will be used. For example, "blob:https://mozilla.org" will be returned as "https://mozilla.org".
