I'm experiencing an issue with cordova and npm 7. I'm also experiencing other issues with npm 7 related to fetching of github repos (as often needed with cordova plugins). I've reverted to npm 6. Am I the only one experiencing these issues? From cordova side it seems to ignore some plugins I use and from npm side it fails in CI due to bad integrity value. Are the current recommendation from Cordova side is to keep using version 6 of npm?

You might have to reinstall cordova -- there was a patch that was released some time ago to fix issues with NPM 7 -- not sure if that is what you were experiencing though.

I've managed to upgrade everything to cordova-android 10 and androidX (Yay!). In the release notes I saw the part about app data getting lost due to breaking changes. I saw the flag that allows reverting this change and it seems to work as expected. I have two questions:
- Will this flag be disabled sometime in the future - i.e. is this a temporary solution or is it a long term solution?
- Is there an easy way (or documented way) to migrate the data? I'm saving the app state in indexDB using dexie. I have no way to know when the user will update the app. where can I save data in order to migrate it? Do I need to upload all the users data to the server now to allow this migration? Using the file system in android 10+ is problematic as you know. I'm honestly not sure how to handle this. Most of the data is not really stored locally, but doing this upgrade I'll need all my users to login again, download a lot of stuff that's already cached on their devices, it's not impossible, but it's also not a great user experience.

- The flag will be there for the foreseeable future, but Google has introduced more and more restrictions of file URL content in newer SDK versions, so functionality might end up breaking in future Android versions.
- There was a long discussion about this issue on the mailing list, and the ultimate conclusion is that each app needs to evaluate if/how to migrate its data. Cordova can't do a 1-size-fits-all solution because different apps have different requirements and data structures. If you can re-create your data by having your users login again, that is probably the simplest solution. Migrating the data itself is a bit tricky and involves a plugin to copy LevelDB files around on the device filesystem, and trying to get them in the correct spot before the webview loads, and you need to deal with failure cases and not overwriting new data and stuff like that π

Not just leveldb... if the device happens to be using webview < 78 or 79 ... the webview uses sqlite databases instead.

@norman137 says
so some devices you may have to migrate from sqlite databases, other devices might be leveldb

Most of the data will be downloaded upon login. It's just might take about 5-15 minutes for a user to get all the data he had before the upgrade. The app is intended for offline usage (maps, points of interest, routes), so if this happens just before you go offline it's bad. But I understand there's no easy solution or one that will help all. Thanks again for the fast response and detailed answers!

I have something similar requirements... Our apps display maps and it has a network of roads for users where they manage conditions of roads -- and it has offline capability, since the user doesn't always have an internet connection when out on the field, especially in rural areas.
Since UIWebView -> WKWebView migration, we started moving all storage away from browser-based storage so that we are in more control over the data. Generally we rely on SQlite instead using a cordova plugin, but depending on the complexity of the dataset, flat json files sometimes works as well.

@norman137 says
There's a lot of issues with the cordova-plugin-file plugin but virtually all of those issues are related to external storage... so if you just stick within internal storage you'll be fine.

Yea, I agree, but I'm also writing a site that uses the same infrastructure, using sqlite in a website is not possible. Sure, I can abstract the DAL layer and use stuff differently in web browser and app, but testing in the browser is a lot easier than testing on a device (for me at least) π and the more common code I use the lest tests I need to do, in theory...

audios are played via javascript (HTML5 audio element created with

So I've reworked our entire application to use CORS and enabled the CORSFilter on all servers - only to realise safari blocks session cookies and I can't use withCredentials? FFS
