Domain Name Sanity is a guide to domains for the web-adjacent. It clarifies domains and makes their behavior predictable and debuggable. This book includes the tools and information you need to set up, maintain, and troubleshoot any domain. It even describes how to set up a TLS certificate from scratch.
The book is written in an informal, conversational style, as if we’re talking while sitting in comfortable chairs. This is not another boring technical manual or RFC, promise.
Why read this book?
As a developer, I found domains to be unpredictable and frustrating. Without deep knowledge, even the simplest tasks ended up taking more time than I wanted. Fortunately, now there's a clear-cut guide to configuring domains for real tasks. Domain Name Sanity uses examples and simple language to explain domains so that everyone (including you!) can use them confidently and effectively.
