UrlMatcher

type-alias

npm Package	@angular/router
Module	import { UrlMatcher } from '@angular/router';
Source	router/src/config.ts

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

Description

A custom URL matcher can be provided when a combination of path and pathMatch isn't expressive enough.

For instance, the following matcher matches html files.

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

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