Wayland is the next-generation display server for Unix-like systems, designed and built by the alumni of the venerable Xorg server, and is the best way to get your application windows onto your user's screens. Readers who have worked with X11 in the past will be pleasantly surprised by Wayland's improvements, and those who are new to graphics on Unix will find it a flexible and powerful system for building graphical applications and desktops.
This book will help you establish a firm understanding of the concepts, design, and implementation of Wayland, and equip you with the tools to build your own Wayland client and server applications. Over the course of your reading, we'll build a mental model of Wayland and establish the rationale that went into its design. Within these pages you should find many "aha!" moments as the intuitive design choices of Wayland become clear, which should help to keep the pages turning. Welcome to the future of open source graphics!

Drew DeVault got his start in the Wayland world by building sway, a clone of the popular tiling window manager i3. It is now the most popular tiling Wayland compositor by any measure: users, commit count, and influence. Following its success, Drew gave back to the Wayland community by starting wlroots: unopinionated, composable modules for building a Wayland compositor. Today it is the foundation for dozens of independent compositors, and Drew is one of the foremost experts in Wayland.
