Node.js Design Patterns

This is an absolutely fabulous book on nodejs. It is very well written and the code examples are very good and useful. It is obvious that the author has very deep knowledge of the language and the design patterns he writes of.The book starts with an explanation of the fundamental principles of node and of how asynchronous tasks run in node. The book then covers different patterns for writing asynchronous code. Next, streams are explained. For me, these early chapters were extremely useful as asynchronous code and streams are quite new to me and often cause some problems. The other chapters cover design patterns in node, node modules, scaling node apps and messaging and integration patterns.What can I say, this is a must for anyone writing code in node. Everything in the book, including the code examples, are very useful in practice. Although the examples are not unnecessarily complex, I found that reading the book required quite a lot of attention. This may be in part due to the fact that I am new to node, but the book is definitely quite dense in many parts. I think that it is therefore a good idea to either bang out the example codes yourself or at least download them from the publisher's site and go through the code files with a lot of thought.

Read this and you'll get serious and deep understanding of node.js, and specific ways to implement in your project.Great discussion and solutions to avoid the sync vs async design and implementation issues in node.This is the most advanced complete and useful node.js book I've read.I enjoy it very much, and keep coming back to it to help me design and code.Thank you Mario for all the times you didn't go out for beers with your friends so you could publish your bookKudos to Packt and the reviewers. Great job, Great Book!

Good stuff.

In the day and age when most technology books seem to be written in a month by compiling information freely available on the web, it is refreshing to find a book that was written by someone who clearly not only knows what he's talking about extremely well, but also knows how to present the material in a coherent way.I am not going to describe the content of the book, as you can easily get that from a TOC, but I will say this:1. If you are an experienced developer that is new to Node.js and need to get up to speed quickly, read this book2. If you are interested in asynchronous programming patterns and practices, read this book3. If you are writing a JavaScript library that needs to work both in Node and in the browser, read this book4. If you are interested in messaging and integration patterns, read this book5. If you simply want to read an awesome technical book for a change, read this bookThe bottom line -- if you are doing anything with Node, this book should be on your shelf/iPad/Kindle.

I've read basically every Node.js book published on Kindle, and this is the best by far. Even months after reading all the way through this text, I still learn new things each time I browse through its chapters. From a deep-dive into the mechanics of async control flow (promises, streams, etc) to best practices application structure/packaging to architectural strategies for scaling and deploying Node.js apps of all kinds, it's got everything you need to take your Node.js (and JS in general) skills to the next level.

I have bought a number of Node.js books over the past year and this is without a doubt the best. It delves quite a bit deeper than most and I find myself referring to it often.

This is actually a good book with really useful examples of advanced js patterns. Why the 2 stars? because this book is the most poorly written technical book I've ever paid money for. Simple singular / plurals are consistently wrong and some sections are just not intelligible. It's actually pretty easy to find and engage a good editor / proof-reader. So I consider this a fail. If you gave me this book free as an draft work in progress I'd give 5 stars.

An indispensable book for every node developers.

Best book on Node by far

If you, like I, have transitioned to Javascript and Node.js recently, then make this book the second book you read. The first should be a beginner/intermediate level Javascript or Node.js introduction text. This takes you from beginner to expert level on all important aspects of developing professional level Node.js applications which will scale.The writing style is easy to read, and the examples are excellent. Mario Cascario takes a no-nonsense approach to explaining the pros and cons of various tools and techniques, so you can decide for yourself which trade-offs you're willing to make.

Assolutamente suggerito a tutti coloro che conoscono Javascript ma non sono del tutto convinti che Node.js possa essere un'ottima soluzione per lo sviluppo di applicazioni enterprise. Questo libro vi farà completamente cambiare idea e vi introdurrà ai principali design pattern utili per essere immediatamente operativi ed evitare errori grossolani.

This book gives a very nice introduction to node.js. It's focus is on patterns and paradigms. You learn to "think" the node.js way. For each of the chapters there is a small node program that illustrates the point.For me, the way to learn with this book is to read a few pages and then (on the next day) write the example myself. Then I compare it with the solution given in the book.That way I learn to "think" node.js, which is different form just copying some examples or following instructions. This book teaches your to understand the design decisions and the rationale behind node.js.

Whilst there are a plethora of node.js "jump start" books available, this is not one of them, rather this is a node.js deep dive with an emphasis on the inner workings of node.js and how best to take advantage of these to avoid anti-patterns. I thoroughly recommend this read to serious mid-level to senior developers coming from another development language.
