Installation

yarn add postcss-elm-tailwind --dev

# OR

npm i -D postcss-elm-tailwind

Usage

No config

module.exports = {
  plugins: [
    require("tailwindcss"),
    require("postcss-elm-tailwind")()
]
};

With config

module.exports = {
  plugins: [
    require("tailwindcss"),
    require("postcss-elm-tailwind")({
      prefix: "tw-", // you must tell us if you have set a prefix in your tailwind.config.js
      elmFile: "src/Tailwind.elm", // change where the generated Elm module is saved
      elmModule: "Tailwind" // this must match the file name or Elm will complain
    })
  ]
};

See the demo for a full example.

Other things to note

In order to get a small build, you'll need to build Tailwind twice - once without purgecss to build TW.elm with all the classes and once with purgecss so that all the unused classes are removed from your production CSS. See how this is implemented in the demo.
