> Since the library is meant to be used in a web app, how would the app be accessed without internet access

If a website still works when wifi is disabled, it's because the entirety of the application has been downloaded and cached by the browser; no further Network requests are needed—or invoked by something the user might want to do, like scanning another barcode.

If scanning a barcode requires a GET, POST, PUT etc. somewhere, it won't work offline.

If scanning a barcode only requires reusing a cached script/function/asset, it should work offline.

Good points.

If the app is coming out of the cache, IIRC it does not count as a page load and typically the SDK is initialized at page load (where the license check happens). Scanning a barcode doesn't require an HTTP request, just the initialization of library.

But I agree that requiring internet access at some point is a turn-off for lots of people.
