Overview of this book

The MEAN stack is a collection of the most popular modern tools for web development that helps you build fast, robust, and maintainable web applications. Starting with the MEAN core frameworks, this pragmatic guide will explain the key concepts of each framework, how to set them up properly, and how to use popular modules to connect it all together. By following the real-world examples shown in this tutorial, you will scaffold your MEAN application architecture, add an authentication layer, and develop an MVC structure to support your project development. You will learn the best practices of maintaining clear and simple code and will see how to avoid common pitfalls. Finally, you will walk through the different tools and frameworks that will help expedite your daily development cycles.

Managing authentication


Managing an Angular application authentication is a complex issue. The problem is that while the server holds the information about the authenticated user, the Angular application is not aware of that information. One solution is to use a service and ask the server about the authentication status; however, this solution is flawed since all the Angular components will have to wait for the response to return, causing inconsistencies and development overhead. This can be solved using an advanced Angular router object; however, a simpler solution would be to make the Express application render the user object directly in the EJS view and then use an Angular service to serve the object.

Rendering the user object

To render the authenticated user object, you'll have to make several changes. Let's begin by changing the app/controllers/index.server.controller.js file, as follows:

exports.render = function(req, res) {
  const user = (!req.user) ? null : {
    _id: req.user.id...
