Take your application to the next level of high performance using the extensive capabilities of Node.js

About This Book

Analyze, benchmark, and profile your Node.js application to find slow spots, and push it to the limit by eliminating performance bottlenecks
Learn the basis of performance analysis using Node.js
Explore the high performance capabilities of Node.js, along with best practices

In Detail

Node.js is a tool written in C, which allows you to use JavaScript on the server-side. High performance on a platform like Node.js is knowing how to take advantage of every aspect of your hardware, helping memory management act at its best, and correctly deciding how to architect a complex application. Do not panic if your applications start consuming a lot of memory; instead spot the leak and solve it fast with Node.js by monitoring and stopping it before it becomes an issue.

This book will provide you with the skills you need to analyze the performance of your application and monitor the aspects that can and should be. Starting with performance analysis concepts and their importance in helping Node.js developers eliminate performance bottlenecks, this book will take you through development patterns to avoid performance penalties. You will learn the importance of garbage collection and its behaviour,and discover how to profile your processor, allowing better performance and scalability.

You will then learn about the different types of data storage methods. Moving on, you will get to grips with testing and benchmarking applications to avoid unknown application test zones. Lastly, you will explore the limits that external components can impose in your application in the form of bottlenecks.

By following the examples in each chapter, you will discover tips to getting better performing applications by avoiding anti-patterns and stretching the limits of your environment as much as possible.

What You Will Learn

Develop applications using well-defined and well-tested development patterns
Explore memory management and garbage collection to improve performance
Monitor memory changes and analyze heap snapshots
Profile the CPU and improve your code to avoid patterns that force intensive processor usage
Understand the importance of data and when you should cache information.
Learn to to always test your code and benchmark when needed
Extend your application’s scope and know what other elements can influence performance

Who This Book Is For

This bookis for Node.js developers who want a more in-depth knowledge of the platform to improve the performance of their applications. Whether you have a base Node.js background or you are an expert who knows the garbage collector and wants to leverage it to make applications more robust, the examples in this book will benefit you.

Style and approach

This is a practical guide to learning high performance, which even the least experienced developer will comprehend. Small and simple examples help you test concepts yourself and easily adapt them to any application, boosting its performance and preparing it for the real-world.

Definitely not recommended for experienced developers

Reviewed in the United States on January 11, 2017

Verified Purchase

I want to be constructive but I've really been let down by this book, I really feel I deserve my money back :)

The interesting part of the book (memory / CPU profiling) is really limited and doesn't really go deep with more complex examples and so on -- I feel it didn't really add anything to the online articles I have read on the subject, instead it was even less informative.

The book is more of an overview of development practices for Node, from how to use NPM to using mocha to test your code, but lots of things that are mentioned around are really basic (turn on HTTPs, test your code, mocha has timeouts on tests to ensure they dont take long) -- I mean, I didnt expect to read about some of these things since they are really, really basic stuff that everyone should know.

I would definitely discourage experienced developers from purchasing it, as it won't add much to your bag of knowledge. On the other side, if you just got started a few months ago or switched to node after other platforms I would say it has a lot of informative points and lists quite a few best practices, so it could be considered as a good reference on how to generally create "good" node apps.

Node.js High Performance is one of the most complete book you can find out there to setup your server for best possible scenario

Reviewed in the United States on December 8, 2015

I have been Node.js developer since v0.9 and seen it have evolved over time is facinating. There is allways something new to learn.

Node.js High Performance is one of the most complete book you can find out there to setup your server for best possible scenario (lots of traffic). This book introduces you to All of the possible options and settings you can do in Node.JS (as of now, who knows what will the next version bring with it, but that we will read in another book)

Node.js High Performance is really rasy to understand and follow (as most Packt books are). This book is a fantastic resource for a quick tune up of your Node.JS installation.
