In Blazor, what is an "interactive render mode" and how do I use it?

[MisinformedDNA]

I keep reading "interactive render mode" and I'm not sure what to think. Most web pages are interactive, so we would almost always want to enable this, right. Non-interactive render mode seems like it would be an edge case?

Also, how do I enable "interactive render mode" for WASM? In @mkArtak's example, he creates two projects, one for WASM and one for server, but I thought the whole point of Blazor "United" was that I only needed one project to do either.

A large number of websites are non-interactive. I don't know if it's a majority or not, but I'm willing to bet it actually is. A majority of websites are definitely "might as well be non-interactive" if not literally.

WASM, by definition, will always be interactive.

All of this is going from the assumption that "interactive" refers to all non-HTML interactions(basically, JavaScript/WASM) and not things like forms and links.

what is interactive? Is single page web app interactive? If I am not making request to server is the UI interactive? So reactive UI using javascript is interactive, may be if I am making a little request but not too much for example signalR that's still interactive

Anything that mutates the DOM outside of the initial Document page load is interaction. Just to reiterate my first point: An overwhelming majority of modern websites are interactive, but old websites are generally non-interactive.

My second point ("A majority might as well be") was about the fact that most pages uses Vue, React, etc.. even though they're 0 reason to do so.
