MEAN Web Development

By: Amos Q. Haviv

Overview of this book

The MEAN stack is a collection of the most popular modern tools for web development; it comprises MongoDB, Express, AngularJS, and Node.js. Starting with MEAN core frameworks, this project-based 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. Finally, you will walk through the different tools and frameworks that will help expedite your daily development cycles. Watch how your application development grows by learning from the only guide that is solely orientated towards building a full, end-to-end, real-time application using the MEAN stack!

Three-tier web application development

Most web applications are built in a three-tier architecture that consists of three important layers: data, logic, and presentation. In web applications, the application structure usually breaks down to database, server, and client, while in modern web development, it can also be broken into database, server logic, client logic, and client UI.

A popular paradigm of implementing this model is the MVC architectural pattern. In the MVC paradigm, the logic, data, and visualization are separated into three types of objects, each handling its own tasks. The View handles the visual part, taking care of user interaction. The Controller responds to system and user events, commanding the Model and View to change appropriately. The Model handles data manipulation, responding to requests for information or changing its state according to the Controller's instructions. A simple visual representation of MVC is shown in the following diagram:

In the 25 years of web development, many technology stacks became popular building three-tier web applications; among those now ubiquitous stacks, you can find the LAMP stack, the .NET stack, and a rich variety of other frameworks and tools. The main problem with these stacks is that each tier demands a knowledge base that usually exceeds the abilities of a single developer, making teams bigger than they should be, less productive, and exposed to unexpected risks.
