Essential Node.js Security
Essential Node.js Security
for Express Web Applications
About the Book
This book is intended to be a hands-on thorough guide for securing web applications based on Node.js and the Express web application framework. Many of the concepts, tools and practices in this book are primarily based on open source libraries and the author leverages these projects and highlights them.
The main objective of the book is to equip the reader with practical solutions to real world problems, and so this book is heavily saturated with source code examples as well as a high level description of the risks involved with any security topic, and the practical solution to prevent or mitigate it.
Even though Express is chosen as the case for web application framework, many concepts in this book can, and should be taken into account, and implemented with any other framework. Concepts like secure code, nosql injections, secure session management, and others are important security topics and would benefit any Node.js developer whose primary focus is web development.

David Madar
Software Engineer, Hewlett Packard Enterprise
Excellent book. Covers the possible security issues and the right way to discover and deal with them. Written clearly with plenty of examples. A great book for those who wish to enrich their knowledge in security and for those who want to implement practical security solutions in their application.
Ran Bar Zik
Web Developer at AOL
An essential book for every Node.js developer out there. Many security issues can be avoided just by understanding the inherent security risks and this book covers clear description and how to tackle those issues. It is recommended not only for Node.js developers but to all JavaScript developers who want to expand their understanding of security. Security in source code should not be neglected and by reading this book every developer will do a major step towards producing more secure code.
