# URL Handler

The library provides a flexible and efficient way to map URL patterns to their respective handler methods. By defining a set of URL patterns and the corresponding handler functions, this package allows seamless routing, ensuring that each url is processed by the correct function.

#### use(path: string, (url: UrlOptions [, ...args: any]) => any): void
```ts
router.use('/foo/bar/:barId', (url, someMap) => {
    // someMap passed from handle method
    ...
});
```

#### handle(url: string [, additionalData: any [, ...]]) => any): Response
```ts
const someMap = new Map();
...
const res = router.handle('https://domain.xyz/foo/bar/:barId', someMap);
