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.

Common functionalities

There are a few functionalities that we used earlier and some extra functionality to consider before jumping further into development. For example, we used a common headers definition, found under public/src/common/headers.ts:

import { Headers } from 'angular2/http';

const HEADERS = {
  'Content-Type': 'application/json',
  'Accept': 'application/json'

export const contentHeaders = new Headers(HEADERS);

This is simply a way to define constants and use them across the application without repeating yourself. So, basically, we imported Headers from Angular 2 and created a new instance. You can easily add extra fields to this header instance using the append() method, like this for example:

contentHeaders.append('Authorization', 'Bearer <token_value>');

Now there a few other things to consider:

  • When asking the server for resources through the API, we should send the required Bearer token

  • If a user makes a call and the server responds with a status code that equals...
