Just wondering if the development of offline apps will be covered in the final book?

when you compile the application, it becomes a desktop application that can run offline.

and yes, it should. Electron can create apps without connecting to internet if it is desired.

When you deploy an electron app, it will become a desktop application that is offline.

Now, if your main window or JS makes reference to external CDN resources, then yes, you need an internet connection to make those resources available.

My advice is: if you want a 100% offline electron app, make all the resources available in your project directory.
