A function for matching a route against URLs. Implement a custom URL matcher for Route.matcher when a combination of path and pathMatch is not expressive enough. Cannot be used together with path and pathMatch.

The function takes the following arguments and returns a UrlMatchResult object.

• segments : An array of URL segments.
• group : A segment group.
• route : The route to match against.

The following example implementation matches HTML files.

export function htmlFiles(url: UrlSegment[]) {
  return url.length === 1 && url[0].path.endsWith('.html') ? ({consumed: url}) : null;
}

export const routes = [{ matcher: htmlFiles, component: AnyComponent }];
