Hopefully, we've explored at least enough of Progressive Web Apps that they have at least been partially demystified! A lot of the confusion and trouble with building PWAs tends to stem from the fact that there's not always a good starting point for building one. To get the value out of PWAs, you have to have a PWA, but to build a PWA you typically need to demonstrate the value of them! What a whirlwind!

Create React App limits us a little bit in how we can implement Service Workers, which admittedly limits the functionality and usefulness of our PWA. It doesn't hamstring us, by any means, but doing fun tricks with pre-caching networks and API responses, and loading up our application instantly, even if the browser doing the loading is offline in the first place. That being said, it's like many other things in Create React App: an amazing stepping stone and a great way to get moving with PWAs in the future!

In the next and final chapter, we'll tie up a few loose ends with our project and talk a little bit about production builds and ejecting out of Create React App! We'll look at how to take our code and get it into production. We'll also discuss importing some other major libraries into our Create React App project, such as Redux!
