< @angular/routerAngular/docs/8/api/router/urlmatcher



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.

type UrlMatcher = (segments: UrlSegment[], group: UrlSegmentGroup, route: Route) => UrlMatchResult;

Usage notes

The following matcher 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 }];
