Streaming SSR, as I understand it, does not keep a session alive on the server, so if you make interactive components they will still run in the browser.

So I think it's more like Hotwired, because it keeps a session alive on the server, but it's declarative like React, so you just return whatever you want rendered and the VDOM will generate patches for the browser.

More like Phoenix LiveView: https://hexdocs.pm/phoenix_live_view/Phoenix.LiveView.html

Instead of transferring entire components it transfers only the content that has changed since the last render.

So if you have a like button with the number of likes totalling 3, and someone were to hit the like button to increase the count to 4 the only content transferred would literally be a string value of '4'
