You can have those interactions on Rails just like anywhere else. Cloud compute is also absurdly cheap at scale today compared to the past.

How do you manage page-wide data consistency in Rails without a page refresh?

You make sure you're only trying to do frameworkless development on pages where "data consistency" means "the text box displays the text that's in the text box." :-)

There’s multiple approaches. Since everything is server side rendered, you can for example, stream updates through web sockets

Sounds like a lot of latency, waiting for the backend to render a template and send it over the wire every time the user presses a button.

You don’t re render a template. Only what you need to. If it’s a single div then so be it. Which is why it’s SPA-like experience with server side code

And where does that new div come from? It's not a backend template?

In my understanding template would be the entire page. So while an an individual div re-rendering is also technically a template, it's not really the same thing. It's a tiny re-render compared to a page refresh.

Again, this is a different spin on doing things. Rails preaches abandoning the over-complexity of the client-side in the browser and pushing work to the server.

I personally love it. I'm sure someone who is as fast in React as I am in Rails is laughing reading this.

You're going back in forth about whether the html re-render that's sent back over the wire is always the entire page or only the specific element needed.
