[✨] Ability to handle "no internet" mode

[shairez]

Is your feature request related to a problem?

On a mobile device, when users go offline randomly, prefetching might not work

Then a user can click a button, and just see no response.

Describe the solution you'd like

Idea: a way for either the Qwik Loader or some other plugin that get prefetched first to let the user know that code is not loaded because they are offline.

So once a user clicks the button, they see a message (which could be a generic one customized by the app's devs) that interactivity is not possible because they are offline.

This is still a rough idea, but I think it's going to be a common use case where prefetching might fail and users won't know why the app looks interactive but it's not.

Describe alternatives you've considered

1. Qwik loader hook
2. Another plugin that gets prefetched by default after the html loads (though it might suffer from the same problem ironically)

Additional context

it could be implemented by qwikloader emiting an event, that can be captured by other code to handle it:

How about a fallback in case there's no event handler, that just displays an alert?

this is similar to trying to handle skew issue so I'll assign it to myself to figure it out

I think there should be a handler for fail of the dynamic import in the qwikloader.

The handler should do

• handle the error and enqueue the failed import.
• listen to the "online" event of the window object in order to re-import the failed imports.
• resolve the promise of the import after the success of the re-import.

The developers should suppose

• every execution of the QRL can fail when the network is offline.
• to provide error message for that
• or to wait for the network is online again and the QRL being re-executed.

So the QRL may have information to determine that the execution would fail on offline or wait for online.

We moved this issue to qwik-evolution repo to create a RFC discussion for this.
Here is our Qwik RFC process thanks.

Hi guys :)
do we have any update on this feature ?
Is there any way right now to tell the user that the application is broken because we are in offline mode ?
