About the Book
This book is about creating Progressive Web Applications and it walks you through a journey. We start by laying down the foundations of PWAs and the core technology that enables them to exist at the first place. Throughout the book we will be building an application that will become better and better with added, progressive enhancements that include features for installation, server-side rendering and HTML streaming, and 100% offline availability. Each step is going to introduce you to a new concept, eventually allowing you to become familiar with every single aspect of PWAs. Throughout the book we will explore how to manage images for progressive web applications taking user experience into consideration as well.
