URLPattern: port 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 port read-only property of the URLPattern interface is a string containing the pattern used to match the port part of a URL.
This is the normalized value of the port pattern passed to the constructor, or an inherited value from a baseURL passed to the constructor, or the default value ("*"), which matches any port.
Note that it may also be set implicitly to the empty string ("") if the pattern is specified using an url or baseURL string and the port is not explicitly set.
This empty string matches against URLs that use the default port (443).
Value
A string.
Examples
Basic usage
The following example creates a URLPattern object with (80|443|8080) for the port part and logs the property.
This pattern matches any URL that has the port 80, 443, or 8080.
const pattern = new URLPattern({ port: "(80|443|8080)" });
console.log(pattern.port); // "(80|443|8080)"
console.log(pattern.test("http://example.com:8080/")); // true
