Recover input after lost connection

[TechInterMezzo]

When the client/browser loses the connection it returns to the login screen and waits for a new connection.
Then the it automatically logins again and goes to the last visited page.
The problem is that any unsaved changes are lost.
To be fair, in a normal wired network this will likely not happen but there are also the mobile users with unstable connections in certain situations.
Those users repeatedly reported to me that they have a problem with that, especially when filling out big forms or writing long texts.

At the moment I backup all relevant fields to the local sessionStorage on change and restore them on form load.
But this is a lot of manual coding because I can't iterate those fields and have to do that line by line.

Is there any better way to handle that case?

To answer to this unfortunately is that r3 currently is not designed for this use case. While it works well on mobile devices if there is a strong connection, it would need to be redesigned in parts to make this work in the described scenario.

We´d be happy to work on it, but, as always, need to prioritize capabilities that paying customers want. If multiple, or a larger customer really needs this feature and/or someone would be willing to sponsor the dev time, this would be amazing to work on. Our wishlist is long and we can pick only a handful of features for each release.

Storing stuff in localStorage and restoring it after a reconnect is a bruteforce solution that scales badly. I understand why you do not like it. In the current version of r3, I would either make forms smaller if possible (so that they can be submitted quickly) or introduce a draft option to that I can enter form data while regularly saving, before finally submitting it.
