# URLPattern

> How Elide supports the URLPattern global for matching URLs against patterns per the URL Pattern Standard, including `ignoreCase` and `hasRegExpGroups`.

`URLPattern` is a global and follows the [URL Pattern Standard](https://urlpattern.spec.whatwg.org/), including the
`ignoreCase` option and `hasRegExpGroups`.

## Example

```js
// urlpattern.mjs
const route = new URLPattern({ pathname: "/users/:id(\\d+)/:tab?" });

console.log(route.test("https://example.com/users/42"));
console.log(JSON.stringify(route.exec("https://example.com/users/42/posts").pathname.groups));
console.log(route.test("https://example.com/users/alice"));
```

`elide run urlpattern.mjs` prints:

```text
true
{"tab":"posts","id":"42"}
false
```
