Building an Express Application

Express.js is a Node.js web application framework. Express.js makes it easier to use Node.js and leverages its power. In this chapter, we will be creating an application using solely Express.js. Express.js is also a node package. We can use an application generator tool, which lets us create a skeleton of an express app easily, or we can simply create one ourselves from scratch.

In the previous chapter, we learned about what npm is, what a package is, and how to install a package. In this chapter, we will cover the following elements:

What Node.js is and what it can do
The benefits it adds
The basic programming of Node.js
Node.js core and custom modules
An introduction to Express.js
Creation of an application using Express.js
Routes in Express.js
MVC architecture: what it is and what value it adds when implemented in an application
File naming...

Key benefits

Construct modern web applications with Node 10, Express.js, MongoDB, and Vue

Leverage the latest web standards to increase code performance, readability, and cross-compatibility

Harness the power of the JavaScript ecosystem to effectively run, build, and test your full stack applications

Description

Isomorphic JavaScript was the buzzword of the year 2017, allowing developers to utilize a single language throughout their web development stack and build cost-effective and scalable applications. MEVN is a one such modern web development stack consisting of web applications such as MongoDB, Express.js, Vue.js, and Node.js. Hands-On Full-Stack Web Development with Vue.js 2 and Node.js leverages the harmony of these technologies to help you create full-stack web applications. Starting with the core frameworks, this example-based guide explains all the key concepts of frameworks, how to set them up properly, and how to use popular modules to connect them together and make them work cohesively. You will learn all this with the help of real-world examples. In addition to this, you will be able to scaffold web application architecture, add an authentication layer, and develop the MVC structure to support the development of your application. You'll explore how to create data models for your applications and then write REST APIs by exposing your data model to your application. Solely orientated towards building a full, end-to-end application using the MEVN stack, this book will help you understand how your application development grows.

What you will learn

Build an application with Express.js

Create schemas using Mongoose

Develop a single-page application using Vue.js and Express.js

Create RESTful APIs using Express.js

Add test cases to improve the reliability of the application

This is an excellent book so far on an updated MEAN -> MEVN stack.I am mostly reading it for the VUE part of the stack but it has been a great recap of Mongo, Node and Express for me.I am up to Chapter 5 so far and I will update my review when I have completed the rest of the book and the examples.I am also reviewing the book because it has received such bad (undeserved?) reviews.My review gives an alternative opinion.This book has so far met MY objectives which are obviously also determined by my experience.I hope it encourages you to give this book a try as it is the only one I have found covering MEVN.

I'm just hitting chapter 5 out of 10 in the book, and I have to say most of it is solid... Until it's not. The end of chapter 3 is completely useless, as there are several pages of code, but there's is no instruction on where to place the code. The book has you create a templated app using MVC, but then they don't tell you if the code they are showing is going in the model or the controller.The book would have gotten 5 out of 5 stars if it wasn't for this huge hole. I'll update the review as I go through more of the book.Updating this review after getting through chapter 5 (Vue.js) Current rating 2 stars, down from 3The Vue.js chapter is pretty horrible. Most of the chapter is simply code that says copy this into your application. There's very little actual education going on here. I feel after reading this chapter, they could have stuck to Node.js and gone into depth about the directory structure of the pre-created Express site. After chapter 5, feel pretty bummed about this book.

The pack of screen shots and no particularly new information which I defined as something you can hardly find on the Internet. All info is the water-downed version of official documents or worse. Just take a look at official page, which is clearly better since I already knew its contents. If you stuck at your coding, do google, you can find any.I expected this since I knew her as Medium author. For one who is about to purchase, save your money for something valuable.Also I began to doubt this publisher as well.

The book contain a lot of code but it's not described what this code does and what it's needed for. Sometimes it's not even clear at what file this code needs to be added. But the biggest issue I have with the presented examples is that you follow the instructions, just to find out that big part of the code you written to be replaced with a different approach in the next chapter. Why not use a correct approach in the first place? My goal after reading this book is to be able to use the best possible approach and not to waste time on learning some techniques which aren't best practices and will be replaced later on in the book. Also the book contains a lot of incorrect syntax, i.e commas where they shouldn't be, etc. Don't waste your money, find a tutorial on-line it will be more useful. The last nail to the coffin is the code samples on GitHub - you can't simply download a particular file, you need to download the whole chapter where some of the chapters, packed in the countless number of zip files, weights more than a 100 MB. Why not include only the files for each chapter which are modified in this chapter?
