Router

Class Details

errorHandler : ErrorHandler

Error handler that is invoked when a navigation errors.

See ErrorHandler for more information.

navigated : boolean

Indicates if at least one navigation happened.

config : Routes

initialNavigation() : void

Sets up the location change listener and performs the initial navigation.

setUpLocationChangeListener() : void

Sets up the location change listener.

routerState : RouterState

Returns the current route state.

url : string

Returns the current url.

events : Observable<Event>

Returns an observable of route events

resetConfig(config: Routes) : void

Resets the configuration used for navigation and generating links.

Usage

router.resetConfig([
 { path: 'team/:id', component: TeamCmp, children: [
   { path: 'simple', component: SimpleCmp },
   { path: 'user/:name', component: UserCmp }
 ] }
]);

ngOnDestroy()

dispose() : void

Disposes of the router.

createUrlTree(commands: any[], {relativeTo, queryParams, fragment, preserveQueryParams,
                        preserveFragment}?: 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.

Usage

// 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) : Promise<boolean>

Navigate based on the provided url. This navigation is always absolute.

Returns a promise that:

• is resolved with 'true' when navigation succeeds
• is resolved with 'false' when navigation fails
• is rejected when an error happens

Usage

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) : 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:

• is resolved with 'true' when navigation succeeds
• is resolved with 'false' when navigation fails
• is rejected when an error happens

Usage

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.

serializeUrl(url: UrlTree) : string

Serializes a UrlTree into a string.

parseUrl(url: string) : UrlTree

Parses a string into a UrlTree.

isActive(url: string|UrlTree, exact: boolean) : boolean

Returns if the url is activated or not.
