I don't see anything in this post claiming that Rails doesn't support websockets, where are you getting that?

Author here: Not sure why everyone’s taking this as anti-rails or anti-laravel. It’s not. I just shared what worked best for my use case. Real-time updates are built into phoenix through channels and liveview, while in rails it’s handled through Action Cable and Turbo Streams. Both work great, but phoenix’s setup felt more integrated for what I was building.
