Feliz VS Fable.Lit

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/

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:

The other major frameworks I use are tailwindcss for styling and Fable.Lit for the views.

Lit for Lit components.

This is my personal favorite one when it comes to Fable options, Fable.Lit builds on top of lit.dev which is a web component library built on web standards. It brings performant straightforward and inter-framework compatible components to the F# FE landscape since Lit works with DOM elements themselves rather than abstractions you can manipulate component instances like if you were doing vanilla JavaScript except that you can use the F# safety for that.

Around September vite got traction with the vue user base and other users as well. I also studied a bit the vite source code, and even used it for some Fable material for posts. I was trying to make some awareness of Fable.Lit support for Web Components and I wanted to experiment in reality how good vite was, and boi it's awesome If you're starting new projects that depend on node tooling in my opinion, it's your best bet.

I don't know a ton about Fable, but they recently wrapped Google's Lit to allow building functional templating and web components in it: https://fable.io/Fable.Lit/

Seems like a neat project.
