URL: origin property

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 (if explicitly specified, unless it is the default port - 80 and 443 respectively).
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".

Note: This feature is available in Web Workers

Value

A string.

Examples

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

const url = new URL("http://localhost:80/");
console.log(url.origin); // Logs 'http://localhost'

const url = new URL("https://mozilla.org:8080/");
console.log(url.origin); // Logs 'https://mozilla.org:8080'
