angular - While Implementing CanActivate Guard Error as : No provider for HRComponent -


while implementing canactivate guard im getting error : no provider hrcomponent

import { component, oninit } "@angular/core" import { activatedroute, canactivate } "@angular/router" import { loginservice } "../../services/loginservice" @component({     templateurl:"../../../templates/hrmodule/hrmodule.html" }) export class hrcomponent implements canactivate {     constructor(private loginservice: loginservice) { }     canactivate(){         debugger;         alert('active');         return true;     } }

this hrmodile.ts

import { ngmodule } "@angular/core" import { routermodule} "@angular/router" import { hrroute } "../../app/route/hrroute" import { hrcomponent } "../../app/component/hrcomponent/hrcomponent" import { loginservice } "../../app/services/loginservice" @ngmodule({     imports: [routermodule.forchild(hrroute)],     declarations: [hrcomponent],     bootstrap: [hrcomponent ],     providers: [loginservice] })  export class hrmodule { }

this hrroute here wrote canactivate 

import { hrcomponent } "../component/hrcomponent/hrcomponent" export const hrroute = [     { path: "add", component: hrcomponent, canactivate: [hrcomponent]} ];

this html link

    <a [routerlink]="['hrmodule/add']" class="btn btn-primary btn-sm">hrmodule</a>  { path: 'hrmodule', loadchildren: '../../module/hrmodule/hrmodule#hrmodule' },

a guard must service not component.

@injectable() export class hrservice implements canactivate {     constructor(private loginservice: loginservice) { }     canactivate(){         debugger;         alert('active');         return true;     } }

and note cannot bootstrapped component in module. convention bootstrapped component "appcomponent"

@ngmodule({     imports: [routermodule.forchild(hrroute)],     bootstrap: [ @@@ need else here @@@ ],     providers: [loginservice, hrservice ] }) export class hrmodule { }

see docs here more information , example: https://angular.io/api/router/canactivate
