Absolutely. We have extremely varied usage in the wild. From sports/content websites with tens of millions of users (bleacher report, cars.com), to folks running social/chat services with millions of persistent connections, to folks running Phoenix on embedded systems. And as you would expect, there's a ton of "boring business app / JSON API" usage in there as well, so we have a good story about generalized use. The goal of the screencast, as I outlay in the beginning is to show how easy LiveView makes it to build interactive and real-time applications, and a social timeline was a decent way to do that ¯\_(ツ)_/¯

Happy LiveView user here :) Can confirm it can be used in many scenarios. One of my favorites is streaming realtime data to a chart. I serialize my data as JSON in the LiveView template and read it back in from a Hook. Saves me time by not having to create a separate API endpoint. e.g.

  <div
   phx-hook="MyChart"
   data-days="<%= Jason.encode!(days(@balances)) %>"
   data-amounts="<%= Jason.encode!(amounts(@balances)) %>"
  >
   <div phx-update="ignore">
   </div>
  </div>

I'm currently using it to make a restaurant POS. It's very flexible. Everything composes like lego pieces in a very clean and straightforward way with surprisingly little magic.

Yes, think of it like Rails for the Elixir language.

Phoenix -> Elixir

Rails -> Ruby

i'm currently using it to make a board game where updates are pushed live to everyone. it's the most pleasant experience i've ever had writing a webapp.
