Node.js lead at MyUnisoft, Node Security WG
I have finished reading Node.js Secure Coding from Liran Tal. I read the whole thing in an hour without realizing it. I learned and discovered a few things along the way. I laughed at the IFS, didn't see it coming.

Master Node.js Security Through Hands-On Learning and Best Practices
Comprehensive learning path
Whether you're a beginner or an experienced JavaScript developer, this Node.js Secure Coding book takes a comprehensive approach to security. From basic terminology to introduction to Command Injection, you'll learn about assorted patterns of insecure code observed in popular and well-known npm packages.
Hands-on learning
Unlike other security books that rely on theoretical examples, this book is based on real-world vulnerable code found in popular npm packages. You'll get hands-on experience reviewing and fixing security issues in these projects, learning practical security skills and Node.js secure coding best practices.
Best practices and practical takeaways
Each chapter ends with a summary of the lessons learned, highlighting best practices for securing your Node.js code and improving your overall security knowledge of Command Injection vulnerabilities.
Congratulations!
You've leveled up your security skills!
Liran is a tireless advocate for security in the JS ecosystem. He works hard to build bridges, educate developers about security issues, and support Open Source projects working to improve their security posture.

Elevated Reading Experience
Who said books don't need to look good?
Forget boring black and white, ceremonial typeface and scientific-like book formatting.
With an elegant color palette, thoughtful formatting, and carefully chosen fonts, you'll enjoy a unique reading experience. Every page is designed to help you focus on the content and immerse yourself in the learning journey. Get ready to elevate your reading experience.
Beautiful Color Palette
Everything from the book's cover design to notes, code blocks, typography styles and notes has been designed with a color palette that is unique and specially crafted for this book.
Beautifully Rendered Code Blocks
You'll read a lot of code.
More precisely, you will read a lot of vulnerable code.
To make the source code review process as fluent as possible, code blocks are styled with the rogue source highlighter using the base16.monokai.dark theme. This is to provide an effective color contrast.

Frequently Asked Questions
Will I learn Node.js security best practices?
I wrote this book first and foremost as a Node.js coding best practices so you can apply secure coding conventions. You can think of it as a Node.js security checklist that you can apply at work or in your own projects.
Will I learn about Node.js security vulnerabilities?
Yes, more than you realized. Forget common Node.js security tutorials and generic security guides - experience true security expertise with this hands-on approach that will analyze actual npm packages that were found vulnerable, some of which you may use today in your projects, and learn why they were vulnerable and how to fix insecure code.
What programming level is required to benefit from this book?
This book doesn't assume any prior knowledge of security nor advanced knowledge of Node.js. It opens with a short introduction to application security, then to Command Injection class of vulnerabilities, and continues to deep-dive into publicly-known vulnerable npm package versions. You will read a lot of code and learn why it's insecure, and how to fix it.
Can it help with Node.js API security?
Probably. As a backend developer, you may need to resort to process execution APIs such as exec() or spawn() in order to perform image processing off the main thread, or other use-cases. You will learn how to secure your Node.js APIs in reference to preventing common Command Injection pitfalls and insecure coding.
Can I contact the author for additional help or questions?
Yes, anytime. I'm always happy to help! Reach out to me here [liran at lirantal dot com].
Does this book focus on other secure Node.js aspects?
No, it focuses specifically and entirely on Command Injection vulnerabilities and how to prevent them. Regardless, it will likely teach you about application security topics and Node.js security best practices that you can apply in your own projects.
