URLPattern: hostname property
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Note: This feature is available in Web Workers.
The hostname read-only property of the URLPattern interface is a string containing the pattern used to match the hostname part of a URL.
This is the normalized value of the hostname pattern passed to the constructor, an inherited value from a baseURL passed to the constructor, or the default value ("*"), which matches any hostname.
Value
A string.
Examples
Basic usage
The following example creates a URLPattern object with *.example.org for the hostname part and logs the property.
This pattern matches any hostname that is a direct subdomain of example.org.
js
const pattern = new URLPattern("https://*.example.org");
console.log(pattern.hostname); // '*.example.org'
console.log(pattern.test("https://horses.example.org")); // true
