A few new tricks have shipped with the. Specifically, I wanted to see if folks investing in a Blazor component library could still use the excellent HTMX library. If you want to write even less JavaScript, this blog post will be right up your alley. This post will explore how to take a server-rendered component and give it some client-side flair without needing web sockets or web assembly. The client communicates with the server, and the server retains stateful information. There are no persistent connections between the client and the server.

This will give you a way to build your app using Razor Components which are rendered on the server and return static HTML to be displayed in the browser.
