Hologram is definitely in too early state to use it in production as same as LiveView. When there would be more documentation and some roadmap/plans for it (no really detailed - just to be aware where we are) then I would definitely test it a lot and I’m thinking about porting all of the phx mix tasks too.

However to use in prod for the project I’m currently working on I need more features. Missing or undocumented support for some events, DOM API and other things are very important for me. For now in best case I would end up using way too many workarounds which simply does not make much sense …

Whenever this happens, I would definitely wait for more news. I believe that in its final state Hologram would be much better than LiveView for my specific needs.

I love elixir, so I really like the premise of using elixir for the front end too.
Keeping the state on the client and using web sockets for server communication sounds really good. Too good perhaps.
I would use it as a default stack for any kind of web work that I would do (business apps).
