URLPattern: test() method - Web APIs

Limited availability

Note: This feature is available in Web Workers.

The test() method of the URLPattern interface takes a URL or object of URL parts, and returns a boolean indicating if the given input matches the current pattern.

test(input)
test(input, baseURL)

input

The URL or URL parts to match against. This can either be a string, or an object providing the individual URL parts. The object members can be any of protocol, username, password, hostname, port, pathname, search, hash, or baseURL. Omitted parts in the object will be treated as empty strings. If the input cannot be parsed, or a relative URL without a base is provided, the method will return null.

baseURL Optional

A string representing the base URL to use in cases where input is a relative URL. If not specified, it defaults to undefined. If this parameter cannot be parsed, the method will return false.

A boolean.

This example shows how to use the test() method to match a URL against a pattern. The example prints the result of the test() calls to the console.

const pattern = new URLPattern("http{s}?://*.example.com/books/:id");

// Absolute URL strings
console.log(pattern.test("https://store.example.com/books/123")); // true
console.log(pattern.test("https://example.com/books/123")); // false

// Relative URL strings
console.log(pattern.test("/books/123", "http://store.example.com")); // true
console.log(pattern.test("/books/123", "data:text/plain,hello world!")); // false
console.log(pattern.test("/books/123")); // false

// Structured objects
console.log(
  pattern.test({
    pathname: "/books/123",
    baseURL: "http://store.example.com",
  }),
); // true
console.log(
  pattern.test({
    protocol: "https",
    hostname: "store.example.com",
    pathname: "/books/123",
  }),
); // true
console.log(
  pattern.test({
    protocol: "file",
    hostname: "store.example.com",
    pathname: "/books/123",
  }),
); // false
