I hope the mentioned resources will be helpful in continuing your PWA journey. PWAs are an exciting corner of web development that is moving fast; keeping an eye on the preceding authors and creators will help you keep up with the pace of change.
We covered a lot of ground in this book: from nothing to a React app and from a React app to a Progressive Web App. We built an entire application from the ground up and deployed it so that the world could see it. We also made it fast and responsive and able to handle all types of connections.
I hope you're proud of the final application and I hope this book has been useful to you. Good luck with all your PWAs in the future and let's keep progressing the web.
