FSharp.Data.Adaptive VS Feliz

This is not the case though! Fun.Blazor takes advantage of the FSharp.Data.Adaptive library which works more-less like an excel spreadsheet's cells, each value is fixed unless it's being computed by another this allows performant updates on-demand, and with the help of adaptiview() {} it can leverage those same efficient updates to allow performant views in F#, in essence adaptiviews are hook-like abstractions.

NOTE: You can try this with the Feliz codebase, which is larger and has multiple .fsproj files. But as you will find out, the project structure is laid out just like we've seen here.

Feliz to create react apps, the most mature option.

The Feliz DSL https://zaid-ajaj.github.io/Feliz/ looks fairly similar to Reagent or there's Fable.Lit https://fable.io/Fable.Lit/ which is more like jsx in that you write the html directly, adding active components via interpolated string mechanisms. There is a VS Code add in that gives you html+css syntax highlighting and auto complete inside your F# files.

Feliz is a DSL for React, and paired with Vite give a hot reload experience that's close to the same as JS/TS, even the React dev tools work fine. Nobody has a ready to go package/template up right now but there's little stopping you from creating a NextJS app.

It means it's similar to the Feliz DSL used to build React web apps: https://zaid-ajaj.github.io/Feliz/

Feliz

I'm curious to see how this goes, F# seems to excel at these type of DSL's (e.g. Feliz, a react DSL is a joy), a big part thanks to type inference and list comprehensions which are a game changer for that pesky conditional rendering.

if you've ever used Feliz or Avalonia.FuncUI then this DSL will make you feel at home, it's less verbose than the original DSL and gives you basically the same benefits, in the case of Fun.Blazor is slightly less performant but it is a viable alternative

Along with Fable highly recommend a look at Feliz. A joy to work with and its ViewEngine can also be separately used w/ Giraffe if you enjoy the syntax:
