render_sync

If I understand correctly, Chris McCord actually did something similar back in his Rails days (https://github.com/chrismccord/render_sync), but the issues he ran into actually led him to create both Phoenix and, eventually, LiveView. I'm sure others are better at explaining the details, but from what I gather this approach is now more viable than it was in the past with other stacks because 1) Phoenix is really efficient and fast with rendering templates, 2) The Erlang/Elixir-specific channels/process approach makes it much easier to have tons of websocket connections open and maintaining state, and perhaps 3) javascript got a lot faster.

Try using https://github.com/chrismccord/sync (real-time Rails partials with Pusher or Faye). Or rewriting the app in Meteor is also a good option. I used to be a Rails developer but I am currently making the switch to Meteor.

Yeah I think so if I grok what this is doing... One interesting approach I came across recently was: https://github.com/chrismccord/sync

I've been experimenting along these lines with making Rails' partial real-time using websockets and it works quite well for Basecamp/Github style apps. Basically you can get "true" MVC while using your existing erb/haml views and you get real-time updates for all connected clients. Some web apps that are replicating desktop like behavior require full client-side MVC, but I think many apps can hit a sweet spot and get the best of both words of server-side rendering with realtime updates. project: https://github.com/chrismccord/sync
