{{APIRef("URL Pattern API")}} {{AvailableInWorkers}}
The pathname read-only property of the {{domxref("URLPattern")}} interface is a string containing the pattern used to match the pathname part of a URL.
This is the normalized value of the pathname pattern passed to the constructor, an inherited value from a baseURL passed to the constructor, or the default value ("*"), which matches any path.
A string.
The following example creates a {{domxref("URLPattern")}} object with /books/:id(\\d) for the pathname part and logs the property.
This pattern matches any URL that starts with /books/, followed by an integer.
const pattern = new URLPattern({ pathname: "/books/:id(\\d)" });
console.log(pattern.pathname); // "/books/:id(\\d)"
console.log(pattern.test("https://example.com/books/8")); // true
