Drupal at your fingertips: A Drupal 9 & 10 developer's quick code reference

Drupal 9/10 developers reference guide with tested proven code used in the real world for secure, performant, scalable websites.

This book is a quick reference for developers creating Drupal sites. While working on such sites during my career, I have gathered a large collection of notes and code which I use for my reference. I hope it will be useful for you, too. I've provided tested code samples for almost every topic. My goal is to save you having to dig through lots of search results to find the code snippet you need to get your job done.
