I feel that the simplicity of just building on the server and pushing the updates across the wire is where we are heading. So a lot less double up, with regards needing to write both for the server and client. Validation especially will just need to be written once.

Although I do feel Phoenix Liveview is a better option because they implement sockets.

Also saw this update today they will allow you to trigger javascript on the client without the sever round trip, it's one of the things people get a bit stuck understanding. Generally they think to pop open a modal or menu requires a round trip to the server but really you should be using Alpine.js or similar for such things. This new pending update remove the requirement of needing a framework like Alpine. https://github.com/phoenixframework/phoenix_live_view/pull/1...
