Build fast, reliable web applications using the latest web development technologies. This book provides step-by-step learning through the process of transforming a "traditional" web app into a high-performing progressive web app, leveraging principles and lessons taught throughout the book. You will learn to improve the performance, reliability, reach, and user engagement of mobile web applications through the use of specific, practical examples. Because most non-trivial web applications developed today use JavaScript frameworks, you will learn about the most popular frameworks offering PWA right out of the box, including React, Preact, Vue.js, Angular, and Ionic. You also will learn which tools to enlist to measure your application's performance, such as Google's Lighthouse.Beginning Progressive Web App Development includes best practices to make your app work even when an end user has a poor or no Internet connection, and to send notifications and reminders with the Notification and Push APIs to keep your users engaged. You'll come away with an understanding of the technologies--application shells, server push technology, and caching--that will allow you to rapidly deliver content to your users.As important as it is to provide mobile users with a great experience, the principles of PWAs aren't limited to smartphones. Most of what you will learn in this book is directly applicable to web applications on all screen sizes.

O autorze

Dennis Sheppard is the VP of Technology at NextTier Education, a startup dedicated to helping students navigate the college selection process. Long before that, though, Dennis graduated from Louisiana Tech University with a computer science degree, and went on to develop and architect software for almost a dozen different industries. With over 10 years of professional software development experience, he has built his share of web applications, for both mobile and desktop. Because of that, Dennis strongly believes in the power of Progressive Web Apps to further help the tech world reach those who do not have access to the fastest networks and latest and greatest phones. He was born and raised in the deep south, but migrated to the suburbs of Chicago where he lives with his wife, a set of twins who are growing up way too fast, and an arthritic but playful golden retriever.
