Progressive Web Application Development by Example

By: Chris Love

Overview of this book

Are you a developer that wants to create truly cross-platform user experiences with a minimal footprint, free of store restrictions and features customers want? Then you need to get to grips with Progressive Web Applications (PWAs), a perfect amalgamation of web and mobile applications with a blazing-fast response time. Progressive Web Application Development by Example helps you explore concepts of the PWA development by enabling you to develop three projects, starting with a 2048 game. In this game, you will review parts of a web manifest file and understand how a browser uses properties to define the home screen experience. You will then move on to learning how to develop and use a podcast client and be introduced to service workers. The application will demonstrate how service workers are registered and updated. In addition to this, you will review a caching API so that you have a firm understanding of how to use the cache within a service worker, and you'll discover core caching strategies and how to code them within a service worker. Finally, you will study how to build a tickets application, wherein you’ll apply advanced service worker techniques, such as cache invalidation. Also, you'll learn about tools you can use to validate your applications and scaffold them for quality and consistency. By the end of the book, you will have walked through browser developer tools, node modules, and online tools for creating high-quality PWAs.

Summary

This has been a very long chapter with some advanced concepts being covered. You learned how to trigger different caching strategies based on the request URL, modularizing the service worker logic, and employing cache invalidation strategies. Plus, you got to play with a new progressive web app!

There was a lot of valuable information and source code covered in this chapter, but these examples should only serve as a base reference for your applications. Not only should you be a good steward of the storage your application is allocated, but you should be mindful of your users' data plans.

In the next chapter, we'll continue to review how to use service workers and caching to make applications perform better. You will also see how to use available tools to evaluate and diagnose performance issues so that you can make a better application.
