Overview of this book

The MEAN stack is a combination of the most popular web development frameworks available—MongoDB, Angular, Express, and Node.js used together to offer a powerful and comprehensive full stack web development solution. It is the modern day web dev alternative to the old LAMP stack. It works by allowing AngularJS to handle the front end, and selecting Mongo, Express, and Node to handle the back-end development, which makes increasing sense to forward-thinking web developers. The MEAN stack is great if you want to prototype complex web applications. This book will enable you to build a better foundation for your AngularJS apps. Each chapter covers a complete, single, advanced end-to-end project. You’ll learn how to build complex real-life applications with the MEAN stack and few more advanced projects. You will become familiar with WebSockets and build real-time web applications, as well as create auto-destructing entities. Later, we will combine server-side rendering techniques with a single page application approach. You’ll build a fun project and see how to work with monetary data in Mongo. You will also find out how to a build real-time e-commerce application. By the end of this book, you will be a lot more confident in developing real-time, complex web applications using the MEAN stack.

-user component

In order to authenticate users, we have added some extra functionality to the auth service to enable us to sign in a user. Because we are not persisting the state of a user on the backend—in other words, our backend is stateless—we have to store the current state of the user on the frontend.

Remember that we created an endpoint that will issue us a token for a valid username-and-password tuple. We are going to use that endpoint to retrieve a token that will grant us access to the rest of the API endpoints.

Our sign-in component is fairly simple and it's really reused from the previous chapter, but let's refresh our memory and take a look at it. SigninComponent is found under public/src/auth/components/signin.component.ts:

import { Component } from 'angular2/core';
import { Router, RouterLink } from 'angular2/router';
import { AuthService } from '../services/auth.service';

    selector: 'signin',
    directives: [
    template: `
