localStorage Angular 4 not accessible

I'm building a website using angular 4 and nodejs. When I try to log in, node sends the data, to angular, which works fine. Its just that when I attempt the login, data doesn't gets stored in local storage.

Here is the code of auth.services.ts

import { Injectable } from '@angular/core';
import { Http, Headers } from '@angular/http';
import 'rxjs/add/operator/map';
import { tokenNotExpired }  from 'angular2-jwt';
import { Router } from '@angular/router';


//import { User } from '../../User';

@Injectable()
export class AuthService {
    authToken: any;
    user: any;

    constructor(private http:Http, private router: Router) {
      console.log("authorization service initialized...");
    }

    signIn(user) {
      let headers = new Headers();
      headers.append('Content-Type', 'application/json');
      return this.http.post('http://localhost:3000/users/login', JSON.stringify(user), {headers: headers})
          .map(res => res.json());
    }

    storeUserData(token, user) {
      console.log("storeuserdata");
      localStorage.setItem('id_token', token);
      localStorage.setItem('user', JSON.stringify(user));
      this.authToken = token;
      this.user = user;
    }

    logout() {
      this.authToken = null;
      this.user = null;
      localStorage.clear();
      this.router.navigateByUrl('/');
    }

    getProfile() {
      let headers = new Headers();
      this.loadToken();
      headers.append('Authorization', this.authToken);
      headers.append('Content-type', 'application/json');
      return this.http.get('http://localhost:3000/users/profile', {headers: headers})
        .map(res => res.json());
    }

    loadToken() {
      this.authToken = localStorage.getItem('id_token');
    }

    loggedIn() {
      return tokenNotExpired();
    }
}

Here is the navbar.component.ts since it contains the login part

import { Component, OnInit } from '@angular/core';
import { FormGroup, FormControl, Validators} from '@angular/forms';
import { Router } from '@angular/router';

import { AuthService } from '../../services/auth.service';
//import { User } from '../../../User';


@Component({
  moduleId: module.id,
  selector: 'navbar',
  templateUrl: `./navbar.component.html`,
})
export class NavBarComponent implements OnInit{
  signInForm: FormGroup;

  constructor(private authService: AuthService, private router: Router) {}

  OnSignIn() {
      const user = {
        email: this.signInForm.value.email,
        password: this.signInForm.value.password
      };
      this.authService.signIn(user)
          .subscribe(
              data => {
                  console.log(data);
                  if (data.success) {
                    this.authService.storeUserData(data.token, data.user);
                    this.router.navigateByUrl('profile');
                  } else {

                  }
              },
              error => console.log(error)
          );
      this.signInForm.reset();
  }

  ngOnInit() {
      this.signInForm = new FormGroup({
        email: new FormControl(null, [
          Validators.required,
          Validators.pattern("[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?")
        ]),
        password: new FormControl(null, Validators.required)
      });
  }

  onLogout() {
    this.authService.logout();
  }
}

This is what I receive when I attempt login

Object {success: true, token: "JWT eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyIkX18iO…Tc0fQ.rte25znZW9oASt-6scViAbA37W1DzXxCcg0Z_CMKWTY", user: Object}

and I also get success from the node js part.

When I build this website I was using angular 2. I got busy with my classes and didn't have time to finish it and angular 4 was released. I copied all the code to a fresh directory and made sure that all the node modules are build from start.

Here is my package.json that i had before:

When I run the app with old version of node_modules, it works finne but when I use the new version, user never logs in.

Can someone please help me with this? Thanks
