Refer this code, auth.ts file

import { CanActivate } from '@angular/router';
import { Injectable } from '@angular/core';
import {  } from 'angular-2-local-storage';
import { Router } from '@angular/router';

@Injectable()
export class AuthGuard implements CanActivate {
constructor(public localStorageService:LocalStorageService, private router: Router){}
canActivate() {
// Imaginary method that is supposed to validate an auth token
// and return a boolean
var logInStatus         =   this.localStorageService.get('logInStatus');
if(logInStatus == 1){
    console.log('****** log in status 1*****')
    return true;
}else{
    console.log('****** log in status not 1 *****')
    this.router.navigate(['/']);
    return false;
}


}

}
// *****And the app.routes.ts file is as follow ******//
      import {  Routes  } from '@angular/router';
      import {  HomePageComponent   } from './home-page/home- page.component';
      import {  WatchComponent  } from './watch/watch.component';
      import {  TeachersPageComponent   } from './teachers-page/teachers-page.component';
      import {  UserDashboardComponent  } from './user-dashboard/user- dashboard.component';
      import {  FormOneComponent    } from './form-one/form-one.component';
      import {  FormTwoComponent    } from './form-two/form-two.component';
      import {  AuthGuard   } from './authguard';
      import {  LoginDetailsComponent } from './login-details/login-details.component';
      import {  TransactionResolver } from './trans.resolver'
      export const routes:Routes    =   [
    { path:'',              component:HomePageComponent                                                 },
    { path:'watch',         component:WatchComponent                                                },
    { path:'teachers',      component:TeachersPageComponent                                         },
    { path:'dashboard',     component:UserDashboardComponent,       canActivate: [AuthGuard],   resolve: { dashboardData:TransactionResolver } },
    { path:'formone',       component:FormOneComponent,                 canActivate: [AuthGuard],   resolve: { dashboardData:TransactionResolver } },
    { path:'formtwo',       component:FormTwoComponent,                 canActivate: [AuthGuard],   resolve: { dashboardData:TransactionResolver } },
    { path:'login-details', component:LoginDetailsComponent,            canActivate: [AuthGuard]    },
