Ramstack.HtmxToolkit

Strongly typed HTMX integration for ASP.NET Core MVC, Razor Pages, and Minimal APIs.

Read HTMX request headers through C# properties, return response instructions with a fluent API, and generate request URLs through ASP.NET Core routing. The toolkit also provides MVC action attributes, version-specific HTMX configuration, and automatic antiforgery token delivery through the Toolkit script.
