If not SPA, which technologies would you suggest for a web app similar to an IoT dashboard, with gauges and other UI elements that update every second? The server is written in ASP.NET Core. I was considering Blazor server side but it does not seem to be very popular (compared to react, Vue, angular, etc) and I am not sure it's a good choice for the long term (MS likes to kill UI technologies). Approaches like htmx and unpoly do not seem to be appropriate if a large portion of UI needs to update frequently (feels similar to implementing the Blazor approach but inefficiently).
