Suppose that the component s route you want to refresh is view  then use this   this router routeReuseStrategy shouldReuseRoute   function  future  ActivatedRouteSnapshot  curr  ActivatedRouteSnapshot      if  future url toString        view   amp  amp  curr url toString       future url toString          return false        return  future routeConfig     curr routeConfig         you can add a debugger inside the method to know what is the exact route will come after navigate to  departments  id employees

This can now be done in Angular 5 1 using the onSameUrlNavigation property of the Router config    I have added a blog explaining how here but the gist of it is as follows   https   medium com engineering-on-the-incline reloading-current-route-on-click-angular-5-1a1bfc740ab2   In your router config enable onSameUrlNavigation option  setting it to  reload   This causes the Router to fire an events cycle when you try to navigate to a route that is active already    ngModule    imports   RouterModule forRoot routes   onSameUrlNavigation   reload       exports   RouterModule         In your route definitions  set runGuardsAndResolvers to always  This will tell the router to always kick off the guards and resolvers cycles  firing associated events   export const routes  Routes           path   invites      component  InviteComponent     children                  path             loadChildren     pages invites invites module InvitesModule                    canActivate   AuthenticationGuard      runGuardsAndResolvers   always          Finally  in each component that you would like to enable reloading  you need to handle the events  This can be done by importing the router  binding onto the events and invoking an initialisation method that resets the state of your component and re-fetches data if required   export class InviteComponent implements OnInit  OnDestroy    navigationSubscription         constructor            your declarations here    private router  Router             subscribe to the router events  Store the subscription so we can       unsubscribe later     this navigationSubscription   this router events subscribe  e  any    gt            If it is a NavigationEnd event re-initalise the component      if  e instanceof NavigationEnd           this initialiseInvites                       initialiseInvites           Set default values and re-fetch any data you need       ngOnDestroy        if  this navigationSubscription         this navigationSubscription unsubscribe                With all of these steps in place  you should have route reloading enabled

Found a quick and straight-forward solution that doesn t require to tinker with the inner workings of angular   Basically  Just create an alternate route with the same destination module and just toggle between them   const routes  Routes             path   gesuch       loadChildren     sections gesuch gesuch module GesuchModule               path   gesuch-neu       loadChildren     sections gesuch gesuch module GesuchModule           And here the toggeling menu    lt ul class  navigation  gt       lt li routerLink   gesuch-neu   ngIf   gesuch      getSection    gt Gesuch lt  li gt       lt li routerLink   gesuch   ngIf   gesuch      getSection    gt Gesuch lt  li gt   lt  ul gt    Hope it helps

EDIT  For newer versions of Angular  5 1   use answer suggested by  Simon McClive  Old answer  I found this workaround on a GitHub feature request for Angular   this  router routeReuseStrategy shouldReuseRoute   function        return false      this  router events subscribe  evt    gt        if  evt instanceof NavigationEnd            this  router navigated   false          window scrollTo 0  0               I tried adding this to my app component ts ngOnInit function  and it sure worked  All further clicks on the same link now reloads the component and data   Link to original GitHub feature request  Credit goes to mihaicux2 on GitHub   I tested this on version 4 0 0-rc 3 with import   Router  NavigationEnd   from   angular router

Solved a similar scenario by using a dummy component and route for reload  which actually does a redirect  This definitely doesn t cover all user scenarios but just worked for my scenario   import   Component  OnInit   from   angular core   import   Router  ActivatedRoute   from   angular router   import   Http   from   angular http     Component     selector   reload     template         lt h1 gt Reloading    lt  h1 gt          export class ReloadComponent implements OnInit    constructor private router  Router  private route  ActivatedRoute           ngOnInit         const url   this route snapshot pathFromRoot pop   url map u   gt  u path  join           this router navigateByUrl url           The routing is wired to catch all urls using a wildcard   import   RouterModule   from   angular router   import   NgModule   from   angular core   import   LoginViewComponent   from    views login login component   import   HomeViewComponent   from    views home home component   import   ReloadComponent   from    views reload reload component     NgModule     declarations         LoginViewComponent  HomeViewComponent  ReloadComponent        imports        RouterModule forRoot           path   login   component  LoginViewComponent            path   home   component  HomeViewComponent                     path   reload           children               path                  component  ReloadComponent                              path        redirectTo   login                 exports        RouterModule         providers          export class AppRoutingModule      To use this  we just need to add reload to the url where we want to go     this router navigateByUrl  reload some route again fresh    skipLocationChange  true

Very frustrating that Angular still doesn t seem to include a good solution for this  I have raised a github issue here  https   github com angular angular issues 31843  In the meantime  this is my workaround  It builds on some of the other solutions  suggested above  but I think it s a little more robust  It involves wrapping the Router service in a  ReloadRouter   which takes care of the reload functionality and also adds a RELOAD PLACEHOLDER to the core router configuration  This is used for the interim navigation and avoids triggering any other routes  or guards    Note  Only use the ReloadRouter in those cases when you want the reload functionality  Use the normal Router otherwise   import   Injectable   from   angular core   import   NavigationExtras  Router   from   angular router     Injectable     providedIn   root     export class ReloadRouter     constructor public readonly router  Router        router config unshift   path   RELOAD PLACEHOLDER             public navigate commands  any    extras   NavigationExtras   Promise lt boolean gt        return this router        navigateByUrl   RELOAD PLACEHOLDER    skipLocationChange  true          then      gt  this router navigate commands  extras

There are different approaches to refresh the current route  Change router behaviour  Since Angular 5 1  Set the routers onSameUrlNavigation to  reload   This will emit the router events on same URL Navigation     You can then handle them by subscribing to a route You can use it with the combination of runGuardsAndResolvers to rerun resolvers   Leave the router untouched    Pass a refresh queryParam with the current timestamp in the URL and subscribe to queryParams in your routed component   Use the activate Event of the router-outlet to get a hold of the routed component    I have written a more detailed explanation under https   medium com  kevinkreuzer refresh-current-route-in-angular-512a19d58f6e  Hope this helps

If your navigate   doesn t change the URL that already shown on the address bar of your browser  the router has nothing to do  It s not the router s job to refresh the data  If you want to refresh the data  create a service injected into the component and invoke the load function on the service  If the new data will be retrieved  it ll update the view via bindings
