Feature Flags Book: Feature Flags, An Introduction

Published in Comments (2)

I've been working in the web development industry since 1999; and, before 2015, I'd never heard the term, "feature flag" (or "feature toggle", or "feature switch"). When my Director of Product—Christopher Andersson—pulled me aside and suggested that feature flags might help us with our company's downtime problem, I didn't know what he was talking about.

Cut to me in 2024—after 9 years of trial and error—and I can't imagine building another product or platform without feature flags. They have become a critical part of my success. I put feature flags in the same category as I do logs and metrics: the essential services upon which all product performance and stability are built.

In 2023, I published a book titled, "Feature Flags: Transform Your Product Development Workflow". This book contains everything that I've learned over the last 7 years about integrating feature flags into my product development. But, a static book can only take you so far. In an effort to make the book more interactive, I've created a series of blog posts—one per chapter—that provide a place in which the readers and I can discuss the content. You can purchase the book and / or read a preview of each chapter on the book's mini-site. Feel free to leave a question or a comment down below.

So, I know of the LaunchDarkly book; but, made the decision to basically look at no prior art when I wrote my book. Since I've never written a book before, and certainly not one on this topic, I was afraid that reading anything like-minded books would anchor me into a position of what a book like this "should" look like. As such, I wanted to just go start to finish without any notion of what is out there.

I'm sure part of that instinct is good; and part of it is vanity. But, it seems that there really aren't many books on Feature Flags to begin with. I appreciate you giving me the low-down on what's in the book—it doesn't seem like it will be much of a value-add for me to go back now and read it.

I believe in love. I believe in compassion. I believe in human rights. I believe that we can afford to give more of these gifts to the world around us because it costs us nothing to be decent and kind and understanding. And, I want you to know that when you land on this site, you are accepted for who you are, no matter how you identify, what truths you live, or whatever kind of goofy shit makes you feel alive! Rock on with your bad self!
