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.

The Auth micro app

The Auth micro app will handle authentications in different scenarios. It's going to be our main entry point to authenticate users, using stateful and stateless approaches.

Our core module already exposes middleware to check whether a user is authenticated or not, and authorization-related middleware. This functionality can be used in any module or micro app.

Defining the class

This is going to be our first micro app, so let's go through a few steps:

  1. Create a new micro app called apps/auth/index.js.

  2. Add the following base content:

    'use strict'
    const express = require('express');
    const router = express.Router();
    const Controller = require('./controller');
    class Auth {
  3. Define the constructor:

      constructor(config, core, app) {
        this.core = core;
        this.controller = new Controller(core); = app;
        this.router = router;
        this.rootUrl = '/auth';
        this.regiterRoutes();, this.router);

    We defined a base URL for our micro app...
