The common retort from SPA devs is "what about offline?" Since LiveView keeps state on the server, it doesn't really work offline.
However, 1) you can add custom JS using LiveView's hooks, which might be enough for very simple offline behavior and 2) many SPAs don't work offline either.
If offline support is a major part of your app's design, LiveView isn't a good fit. But you could still use Phoenix Channels (the building block underneath LiveView) to provide fast push updates to your client.
