Obviously offline support is a clear dealbreaker. The interesting thing about that in context of this convo is that Google Docs also doesn’t work offline. It swaps over to read-only mode as soon as the connection dies.
I can’t think of many web applications I use day to day that are offline capable. I also maintain that for the vast majority, just because SPAs are capable of offline mode, doesn’t mean folks actually implement it. You opt-in to a massive amount of complexity in doing so. That said, if you need it, you need it, but I find most folks don’t bother implementing it just because they can. So vast majority of web apps today are already on the network-on-the-interaction path.
Carrying on working while offline, optimistic updates that require pre-rendering the full UI element before hitting the server, and particularly large HTML documents are all things that would point towards client code rather than LV, bu there’s some gray area.
