AngularJS used the ngRoute module to run simple routers with basic features. It enables deep linking of URLs to components and views by mapping the path to the routes configured using the $routeProvider service. AngularJS 1.x needs the ngRoute module to be installed to implement routing in an application.
Angular introduced a Component Router that deep links the URL request and navigates to the template or view. It passes parameters, if any, to the respective component that is annotated for this route.
