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.

As you can see, HTTPS is important to implement, but does require some diligence on your part to properly configure your site. As TLS, certificates, and HTTP advances, the barriers that previously held sites back from implementing HTTPS have been removed.

Progressive web applications require HTTPS because it is a higher level of user experience. They also require a registered service worker, which also requires HTTPS. HTTPS unlocks the modern web's capabilities; without it, your website is relegated to a smaller set of capabilities.

Because TLS ensures the conversation between the client and server is not altered by a man in the middle, and because eavesdropping is mitigated, all sites should adopt HTTPS. You are adding a level of trust for your customers, and opening the gates to the latest features the web has to offer.
