HTML5 Storage isn't supported. You'll need to either build a browser for Kobo or use a polyfill.

Alternatively, using LD_PRELOAD to inject the following code might work:

auto s = QWebSettings::globalSettings();
s->setAttribute(QWebSettings::LocalStorageEnabled, true);
auto p = "/mnt/onboard/storage";
s->setOfflineStoragePath(p);
s->enablePersistentStorage(p);

I mentioned in the other thread a change in firmware 4.20 to add some local storage. This apparently stems from https://github.com/kobolabs/Kobo-Reader/issues/59. There is a link in the original report for a page that uses local storage and it works with 4.20.x.

That makes me wonder if this app will work with 4.20.x. But, it could easily be another issue that breaks it. I can't do a test at the moment, but, might have a play over the weekend.

That's interesting. I'll have to take a look at that later and see what I can do with it.

The app also uses other features too new for the WebKit build on the Kobo. For instance, classList will need to be polyfilled.

I've seen that one before (https://github.com/ieb/signalk-eink). I don't understand what you're asking here, though. If you mean it opens, unlike your own one, then it's simply because you need a few compatibility polyfills.

Yes. You'll probably be able to find most of what you need from the babel and es5/6 polyfills on GitHub (or NPM).
