Greetings everyone and thank you for letting me sit and chat with you for a while. The book just came out a few weeks ago, just in time for those of you stuck at home looking for something new to learn.

This book was a lot of fun for me to write, because I was able to come up with essentially three complete sample apps readers could work through with me as they completed the book. It starts with a simple single-page tip calculator app you use to learn how to convert a single page app (SPA) into a Progressive Web App (PWA). You also get to work with the PWA News site (https://pwa-news.com), all sorts of PWA features to the app. The cool thing about the PWA News app is that it's a live, functioning app, so you can watch it work online, see all the features in play, and work with your local copy to add the same features to a base version of the app. For the browser notification section of the book, rather than deliver a contrived sample app to use, I built a simple client app to demo the functionality and a server process to help you manage it. With that in place, you can easily play with the different options as you learn the material.

So who's reading the book right now and has a question or two for me?

Anyone thinking about reading the book and want to know more about what's in it?

One of the things I've always been curious about is how many of the apps you build use browser notifications? We've all encountered sites that immediately prompt you to allow notifications, but how many apps really need that functionality?  I know it's critical for some apps, but do that many apps really need the capability? For a little more than a year, I was responsible for two of Microsoft's Push Services (App Center Push and Azure Notification Hubs), so I studied the market for browser notifications to see what we should offer in that space. I'm curious to see how popular the push notification chapters are in the book.

What's your favorite part of the book so far?
