I never mentioned LiveView in my comment, just Phoenix (you can use Phoenix without LiveView). But, in defense of LiveView, I use it in production - however, you will need something to compliment it for sure - I use Svelte 5, which is great. LV has a learning curve, but it makes development so much better once you get the hang of it, tbh. May need some 2-3 projects to get used to it. My $0.02.
