Express.js: Node.js Framework for Web Application Development (Web App Development Book 2) Kindle Edition

Yes, this book covers fundamental technique to use Express.js. Because Express.js is actually not a complicated module that needs many things to learn, this book is not difficult to read and understand. But... Most of examples have errors. I'd like to say, "MOST" of Examples. These errors are usually minor but sometimes serious and hard to find! Unless you really like to explore the "error-ful" world and catch bugs, you must be not happy about it. I highly doubt if the author really tested these examples. And English sentences are poor, too. Although I'm not a native English speaker, I could find many awkward expressions and sometimes have difficult time to understand. Yes, this book is cheap, and it has a exact value of this price...

As other reviewers have mentioned, all the code examples have significant typos/syntax errors. These errors may seem trivial to more experienced developers but to a beginner it can cause you to spend half an hour to figure out. The content is good for the price and as an introduction, but the syntactical errors make it hard for me to rate it any higher than 2 stars. If there was an errata compendium, the errata would probably be longer than the book itself.

Express js is like a foreign language to me but I managed to understand most of the principles in this book which is a success given my pc literacy. I liked how clearly everything is laid out and it was a good length book. This is a good book for people who are learning this computer art form like me.

The book does a fine job covering the basics. If you are getting started with Express.js, this is the book to buy, but don't expect advanced topics.

Text from Internet

I'm a software engineer with several years of experience with Express.js. This "book" -- if you could call it that -- is absolute garbage.For example, the author mentions that Express.js "Provides a dynamic rendering of HTML pages, depending on the arguments which have been passed to the templates". This is technically incorrect. Express doesn't come with template engines right out of the box. You have to install the template engine (jade, pug, handlebars, etc...) through npm. But this is nothing compared to what followed.There are so many grammatical errors, I believe a ESL student could have written something better! "You also have the choice of using any of the available databases, such as the MongoDB with Mongoose"? Every page seems chock-full of these sorts of butchered statements. And don't get me started on the errors in the code. Did the author even run these on a machine? Here's the first couple of lines of the first code sample:var ex = require('express');var application = express();This code will throw a 'ReferenceError'. You see, the variable 'express' was never set properly. The fix is to either change 'ex' to 'express' in the first line or change 'express()' to 'ex()' in the second line, but that's beside the point. You shouldn't have such a blatant error in the first snippet of code!The chapter lengths are laughable. Chapter one is a whopping six paragraphs in length if you count each of the three bullet points as paragraphs. Honestly, you could take the content of the "Getting Started" and "Guide" tabs of the Express.js site and come out with more content than this festering pile of crap. Nothing is explained. Avoid this abomination like it is the Black Death.

The formatting for the command line instructions is too tiny on a phone and a regular kindle. It's just barely visible in the cloud reader. I didn't finish reading it because I couldn't see all the code.The explanations are terse and the author jumps through the topics quickly. This feels like a KU page-turner.

This book is fully loaded with information's and guidelines on how to learn web development app. I learned the basics of this program and all the terms is easy to understand. This is indeed a very informative book for all web app developers and I highly recommend it.

This kindle book could use a good proof read and general tidy up of the language used to elevate its usefulness. There are some basic editing errors that should have been caught before being published, the initial sample app says listen on port 3000 and then goes on to use 8081. At one point the text refers to POST and GERT methods, all the obvious things that should have been caught early by an editor.

This is a draft, not a book. This thing should not be called a book and be purchasable.It is the same with Node JS from Matthew Gimson.ISBN 9781519354075
