Learning resources are as follows:
- Progressive Web Apps Documentation: Google’s official documentation on Progressive Web Apps. This should be your first stop to brush on concepts or read about best practices. It also provides a summary of the benefits of PWAs and links to tools such as Lighthouse.
- Your First Progressive Web App: A step-by-step tutorial for building your first Progressive Web App, or in your case, your second one. If you want to see what building a PWA without React will look like, check out this tutorial. This is nice and in depth and covers each concept thoroughly.
