Adding guards to Angular 2 routes

_guards.ts

import { Router, CanActivate } from '@angular/router';
import { Injectable } from '@angular/core';

/** **/
class UserToken {}
/** **/
class Permissions {
  canActivate(user: UserToken, id: string): boolean {
    return true;
  }
}

/** **/
@Injectable()
class CanActivateTeam implements CanActivate {
  constructor(private permissions: Permissions, private currentUser: UserToken) {}
  canActivate(
    route: ActivatedRouteSnapshot,
    state: RouterStateSnapshot
  ): Observable<boolean>|Promise<boolean>|boolean {
    return this.permissions.canActivate(this.currentUser, route.params.id);
  }
}
@NgModule({
  imports: [
    RouterModule.forRoot([
      {
        path: 'team/:id',
        component: TeamCmp,
        canActivate: [CanActivateTeam]
      }
    ])
  ],
  providers: [CanActivateTeam, UserToken, Permissions]
})
class AppModule {}

Will enrich when prototype is complete
