We can see the purge has take the CSS down from a potential 3MB to 10KB

I'm not sure what you mean by vscode plugin. Can you explain a little more? (I use vscode, and plugins, including Ionide, but I'm not sure what you want to leverage).

I meant the link I gave in the first message tailwindlabs/tailwindcss-intellisense#154

from sutil.

Is this something that's still on the roadmap? I also think that CSS frameworks should be external to the core library and Bulma shouldn't be included by default.

from sutil.

Thank for the very nice message, I appreciate that.

I agree with you, Bulma will become an additional package at some point. However, you can ignore it. If you write your code like this:

    Html.div [
        class' "w-64 h-3 bg-gradient-to-br"
    ]

and include tailwindcss into the index.html, it should work just fine.

I'll be happy to put together a working example later if you like.

What we could also do is think about an F# wrapper for tailwind too.

from sutil.

I see, my initial thought was that since some work was done for Feliz engine and Sutil uses it, then it can leverage vscode plugin as well, but it doesn't seem to be the case, right? Another big feature of tailwind is the ability to purge unused css, just referencing the whole thing won't make it happen

from sutil.

Feliz was reimplemented in Feliz.Engine, and Feliz.Bulma was ported to Bulma.Engine, partly to support Sutil, but also to support any DOM DSL or application that wants to build DOM.

I'm not sure what you mean by vscode plugin. Can you explain a little more? (I use vscode, and plugins, including Ionide, but I'm not sure what you want to leverage).

Regarding unused CSS: I remember seeing something about that. Let me look into it. At this time, I don't know how the unused CSS is being purged. It's possible we can make that work, but I'll need to study it.

from sutil.

..OK.. it's possible we can make use of tailwind's purgecss command - it works by searching for class names, and then (I think) strips out unused rules from the CSS. In theory, this could work without any modifications as part of the fable build sequence.

from sutil.

An update: I have Sutil using tailwind, and purging unused classes. I will check something in later.

Next steps:

• Check basic example in
• Either add intellisense support or create as typed-wrapper (like the Bulma Engine in Sutil). Otherwise you can't tell if you've used a valid class name.

I notice that we may be able to get some use of the Sutil feature 'addClass':

let appStyle = [
    rule "button" [
        addClass "bg-red-50 p-2"
        // Other css styles if you like, but then that's a little non-tailwind
    ]
]   

This says that any <button> element will have classes bg-red and p-2

from sutil.

As I said, I'll create a new repo sutil-template-tailwind, but here's how it looks so far.

module App

open Sutil
open Sutil.DOM
open Sutil.Attr

let view() =
    Html.div [
        class' "p-1 bg-gray-200 text-red-400"
        text "Hello World"
    ]

view() |> mountElement "sutil-app"

Here's my package.json (I didn't see the point in complicating the webpack.config.js, but you may disagree)

{
  "private": true,
  "scripts": {
    "start": "dotnet fable watch src/App --runWatch npm run pack",
    "build": "dotnet fable       src/App --run npm run pack:prod",

    "pack": "npm run tailwind && webpack serve",    
    "pack:prod": "npm run tailwind:prod && webpack --mode production",

    "tailwind:prod": "NODE_ENV=production tailwindcss-cli build -o public/tailwind.css",
    "tailwind": "tailwindcss-cli build -o public/tailwind.css"
  },
  "dependencies": {
    "webpack": "^5.11.0",
    "webpack-cli": "^4.2.0",
    "webpack-dev-server": "^3.11.0"
  },
  "devDependencies": {
    "autoprefixer": "^10.2.5",
    "postcss": "^8.2.10",
    "tailwindcss": "^2.1.1",
    "tailwindcss-cli": "^0.1.2"
  }
}

tailwind.config.js

module.exports = {
    purge: [
        './src/**/*.fs.js',
    ],
    darkMode: false, // or 'media' or 'class'
    theme: {
        extend: {},
    },
    variants: {
        extend: {},
    },
    plugins: [],
}

and finally index.html

<!doctype html>
<html>
<head>
  <title>Sutil Hello World</title>
  <meta http-equiv='Content-Type' content='text/html; charset=utf-8'>

Wow, thanks for your help! This is already smth to work with, I think this issue can be closed once separate repos are created

from sutil.

One more thing. Add this to VSCode's settings.json, and you can use the Tailwind Intellisense plugin :-)

    "tailwindCSS.experimental.classRegex": [
        "class'\\s+\"([^\"]*)\""
    ],
    "tailwindCSS.includeLanguages": {
        "fsharp": "html",
        "fs": "html"
    }

from sutil.

Example repo here, as promised:

https://github.com/davedawkins/sutil-template-tailwind

from sutil.

I agree with you. It's not a bad time to split these into separate libraries. I'm pleased people are still interested, thank you
