Feature Flags Book: The User Experience (UX) Of Feature Flag Targeting

By on

There are two groups of people affected by feature flag targeting: the people who use your product; and, the people who manage your feature flag system. Most of this book is about the former—I'd like to take a moment and talk about the latter.

When you first experiment with feature flags, you'll almost certainly use your database's primary keys as the value to target. After all, these database keys are the inputs we use most often in our application request processing. So, it's only natural to extend that mindset into the realm of feature flag targeting.


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.

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!
