A library that makes it easier for F# developers to build Blazor applications with functional programming and computation expressions.
Fun.Blazor is a library that enables F# developers to build Blazor applications using functional programming paradigms. It provides computation expression-based DSLs for creating UI components, supports adaptive and Elmish state management models, and offers type-safe CSS styling. The project solves the challenge of writing Blazor code in a way that feels natural and powerful for F# enthusiasts.
F# developers who want to use Blazor for building interactive web applications without sacrificing functional programming idioms. It's also suitable for teams already invested in the .NET ecosystem looking for a more type-safe and expressive UI development experience.
Developers choose Fun.Blazor because it brings the elegance and safety of F# to Blazor development, offering features like computation expressions for DSLs, type-safe CSS, and support for adaptive/Elmish patterns that aren't natively available in C#-centric Blazor.

Uses F# computation expressions for an idiomatic functional style, as shown in code samples like `adapt { ... }` for adaptive views, making UI development more expressive for F# developers.
Recommends adaptive data flow from FSharp.Data.Adaptive for efficient reactivity, with support for Elmish architecture, offering flexible state management options tailored to F# patterns.
Fun.Css enables compile-time validation of CSS properties, reducing runtime styling errors and enhancing code safety in Blazor applications.
Supports Giraffe-style routing familiar to F# web developers, alongside official Blazor routing, easing navigation setup for those coming from F# ecosystems.
Benchmarks indicate rendering is 1.5-4 times slower than Razor C#, which could impact high-traffic or latency-sensitive applications, as seen in the performance comparison table.
As a library targeting F# developers on Blazor, it has limited community support, documentation, and third-party integrations compared to the broader C# Blazor ecosystem.
Requires team familiarity with F# and functional programming concepts, adding a learning curve and tooling complexity for developers not versed in the language.
