# Function: urlMatcherFactory()

```ts
function urlMatcherFactory(config?): {
  compile: <M>(pattern, options?) => CompiledMatcher<M>;
};
```

Defined in: [url-matcher.ts:771](https://github.com/simshanith/lit-ui-router/blob/740888c2b2ba358c4dfa52a122e927df6a604b12/packages/ui-router-server/src/url-matcher.ts#L771)

Creates a matcher compiler — named for core's UrlMatcherFactory, whose
defaults it keeps: strict trailing-slash matching, case-sensitive,
percent-decoding on, and a default squash policy of false.
