Consider creating a bridge + MEW bundle for offline use

This came up while discussing https://github.com/digitalbitbox/bitbox-bridge/issues/7.

Currently, users need to run a separate static file server like python3 -m http.server --bind 127.0.0.1 and open http://localhost:port to access MEW offline. Opening an HTML file directly with a browser is suboptimal. For example, see security considerations and corner cases.

It feels like a bundle of MEW + the bridge including a built-in static file server would be very helpful for those who want to use BitBox02 with MEW offline.

Such a bundle would nicely package everything together: the bridge, MEW release and a static server. It would be an alternative package, released alongside the regular bridge.

I don't know if something changed on MEW's side, but if I clone their repo and do

npm i
npm run dev

I get a fully functioning MEW that works with the BitBox02, locally.

The idea here was to create a complete offline bundle but npm i would need internet connection.

Does MEW even do anything when offline? It also needs to fetch balances etc. somehow. Or maybe it can be used to just sign offline, that would be nice.

Yeah, that's exactly what it seems to say on https://kb.myetherwallet.com/en/offline/using-mew-offline/

The main computer being used to generate the transactions should not be connected to the internet. You can generate a wallet completely offline and send transactions on a different computer, which must be connected to the internet, from our ‘Send Offline’ section.
