Yeah offline or complex client side state management is a good use case for Javascript. There are Hooks and Push Events with Liveview for real time integrations with Liveview in those scenarios. In my experience offline requirements are rare and often in mobile scenarios where a native or Flutter-like approach is a good option. Complex client side state or collaborative features might use something like https://github.com/slab/delta-elixir https://github.com/slab/delta-elixir or https://www.inkandswitch.com/local-first/ https://www.inkandswitch.com/local-first/ which is where I'd want JS.
