Blazor Server and WASM both have issues that make them non-starters for me, namely latency quickly gets out of hand for the former and the latter is far too heavy. The (unfortunate?) reality is that Javascript is unavoidable if you want good bundle sizes and client-side interactivity.

I find HTMX is a better alternative if I'm trying to write as little JS as possible, I find it smooths over the latency issue better and just lets me write normal web app code that feels like a SPA to use.
