linkConstructor
constructor(rootComponentType: Type<any> | null, urlSerializer: UrlSerializer, rootContexts: ChildrenOutletContexts, location: Location, injector: Injector, loader: NgModuleFactoryLoader, compiler: Compiler, config: Routes)
Creates the router service.
linkMembers
get events: Observable<Event>
get routerState: RouterState
errorHandler: ErrorHandler
Error handler that is invoked when a navigation errors.
See ErrorHandler
for more information.
urlHandlingStrategy: UrlHandlingStrategy
Extracts and merges URLs. Used for AngularJS to Angular migrations.
routeReuseStrategy: RouteReuseStrategy
onSameUrlNavigation: 'reload' | 'ignore'
Define what the router should do if it receives a navigation request to the current URL. By default, the router will ignore this navigation. However, this prevents features such as a "refresh" button. Use this option to configure the behavior when navigating to the current URL. Default is 'ignore'.
paramsInheritanceStrategy: 'emptyOnly' | 'always'
Defines how the router merges params, data and resolved data from parent to child routes. Available options are:
'emptyOnly'
, the default, only inherits parent params for path-less or component-less routes.'always'
, enables unconditional inheritance of parent params.
config: Routes
resetConfig(config: Routes): void
Resets the configuration used for navigation and generating links.
linkUsage
router.resetConfig([
{ path: 'team/:id', component: TeamCmp, children: [
{ path: 'simple', component: SimpleCmp },
{ path: 'user/:name', component: UserCmp }
]}
]);
createUrlTree(commands: any[], navigationExtras: NavigationExtras = {}): UrlTree
Applies an array of commands to the current url tree and creates a new url tree.
When given an activate route, applies the given commands starting from the route. When not given a route, applies the given command starting from the root.
linkUsage
// create /team/33/user/11
router.createUrlTree(['/team', 33, 'user', 11]);
// create /team/33;expand=true/user/11
router.createUrlTree(['/team', 33, {expand: true}, 'user', 11]);
// you can collapse static segments like this (this works only with the first passed-in value):
router.createUrlTree(['/team/33/user', userId]);
// If the first segment can contain slashes, and you do not want the router to split it, you
// can do the following:
router.createUrlTree([{segmentPath: '/one/two'}]);
// create /team/33/(user/11//right:chat)
router.createUrlTree(['/team', 33, {outlets: {primary: 'user/11', right: 'chat'}}]);
// remove the right secondary node
router.createUrlTree(['/team', 33, {outlets: {primary: 'user/11', right: null}}]);
// assuming the current url is `/team/33/user/11` and the route points to `user/11`
// navigate to /team/33/user/11/details
router.createUrlTree(['details'], {relativeTo: route});
// navigate to /team/33/user/22
router.createUrlTree(['../22'], {relativeTo: route});
// navigate to /team/44/user/22
router.createUrlTree(['../../team/44/user/22'], {relativeTo: route});
navigateByUrl(url: string | UrlTree, extras: NavigationExtras = { skipLocationChange: false }): Promise<boolean>
Navigate based on the provided url. This navigation is always absolute.
Returns a promise that:
- resolves to 'true' when navigation succeeds,
- resolves to 'false' when navigation fails,
- is rejected when an error happens.
linkUsage
router.navigateByUrl("/team/33/user/11");
// Navigate without updating the URL
router.navigateByUrl("/team/33/user/11", { skipLocationChange: true });
In opposite to navigate
, navigateByUrl
takes a whole URL
and does not apply any delta to the current one.
navigate(commands: any[], extras: NavigationExtras = { skipLocationChange: false }): Promise<boolean>
Navigate based on the provided array of commands and a starting point. If no starting route is provided, the navigation is absolute.
Returns a promise that:
- resolves to 'true' when navigation succeeds,
- resolves to 'false' when navigation fails,
- is rejected when an error happens.
linkUsage
router.navigate(['team', 33, 'user', 11], {relativeTo: route});
// Navigate without updating the URL
router.navigate(['team', 33, 'user', 11], {relativeTo: route, skipLocationChange: true});
In opposite to navigateByUrl
, navigate
always takes a delta that is applied to the current
URL.
