The Conscious React
A comprehensive guide on React Architecture, Design, and Clean Code.
Timeless principles, guidelines, and best practices for building scalable and robust React applications.

Why another book on React?
Many software, business, and soft-skills books are filled with fluff.
I appreciate books that are just long enough to deliver their value and short enough that there's an ‘aha’ moment on nearly every page.
That's the promise of ‘The Conscious React’.
‘The Conscious React’ is not a book about React 101. It doesn't teach React.
Instead, it combines software design and architecture essentials with React, helping you write scalable and testable React apps from first principles.
Why this book?
Most React resources teach you the how. We focus on the why.
Application Structure & Architecture
Learn the principles behind well-structured React applications. Stop guessing where state should live and start designing predictable data flows that scale.
Component Design
Master the art of designing reusable, maintainable components. Each principle comes with context, what to avoid, and what to prefer.
Performance
Real-world strategies for profiling and eliminating performance bottlenecks in your React applications.
Testing & Tooling
Learn testing strategies and essential tooling to ensure your React applications are reliable and maintainable in production.

It is a fantastic and easy read with simple to follow guidelines illustrated with examples. The book has been really beneficial and practical for me from day one.
Petar's book is excellent for React developers at all skill levels and deserves a spot on every React shop's shelf. Each page offers short, simple, and applicable advice.
As a React beginner, this is a great book to guide my choices when developing applications. It is clear, compact and easy to reference whenever needed.
As someone who recently started working with React this book helps me a lot with best-practices approaches and guidance.
Easy, simple, practical tips, and to the point! I totally recommend!
The book has very valuable practical tips and insights. I totally recommend!
I'm a programmer at the Junior level and would like to improve through a combination of study and practice. Having read the first two-dozen pages, I am glad I bought it. I very much like how concise and laconic it is. The book goes from the simple — e.g. component-level best practices — to the more complex — e.g. performance and testing. By following the best practices mentioned, I now better know how to transform my code from being bloated, unoptimised and messy to being organised, structured and more easily scalable. And thanks to the included explanations I can understand the “why” part of the learning process. In summary, a great addition to my e-book collection!

Frequently Asked Questions
The book's target audience is people who are already familiar with React. Ideally, they have implemented an app or two and now want to progress to the next level. If you're a complete beginner, the book may not be the best fit. You'll definitely need it after a few months into your React journey though!
Not at all. However, you'll gain the most from this book if you have some foundations and experience with React but are ready to take it to the next level!
Currently, I only offer the digital version, but this may change if there is demand for a physical version.
