          loader: 'vue-windicss-preprocess',
          options: {
            config: "tailwind.config.js",  // tailwind config file path OR config object (optional)
            compile: false,                // false: interpretation mode; true: compilation mode
            globalPreflight: true,         // set preflight style is global or scoped
            globalUtility: true,           // set utility style is global or scoped
            prefix: 'windi-'               // set compilation mode style prefix

        }
      })
    }
  }
}

Basic Usage

You can write any tailwindcss classes in your .vue files.

<template>
  <div class="py-8 px-8 max-w-sm mx-auto bg-white rounded-xl shadow-md space-y-2 sm:py-4 sm:flex sm:items-center sm:space-y-0 sm:space-x-6">
    <img class="block mx-auto h-24 rounded-full sm:mx-0 sm:flex-shrink-0" src="/img/erin-lindford.jpg" alt="Woman's Face">
    <div class="text-center space-y-2 sm:text-left">
      <div class="space-y-0.5">
        <p class="text-lg text-black font-semibold">
          Erin Lindford
        </p>
        <p class="text-gray-500 font-medium">
          Product Engineer
        </p>
      </div>
      <button class="px-4 py-1 text-sm text-purple-600 font-semibold rounded-full border border-purple-200 hover:text-white hover:bg-purple-600 hover:border-transparent focus:outline-none focus:ring-2 focus:ring-purple-600 focus:ring-offset-2">Message</button>
    </div>
  </div>
</template>

<script>
export default {}
</script>

Compilation mode

This is not css-in-js, windicss only merges and compiles the tailwind classes of each line into a new class. You can try to compile (npm run build) and check the generated css file.

<div class="windi-15wa4me">
  <img class="windi-1q7lotv" src="/img/erin-lindford.jpg" alt="Woman's Face">
  <div class="windi-7831z4">
    <div class="windi-x3f008">
      <p class="windi-2lluw6"> Erin Lindford </p>
      <p class="windi-1caa1b7"> Product Engineer </p>
    </div>
    <button class="windi-d2pog2">Message</button>
  </div>
</div>

/* ... */
.windi-1q7lotv {
  border-radius: 9999px;
  display: block;
  height: 6rem;
  margin-left: auto;
  margin-right: auto;
}
/* ... */
@media (min-width: 640px) {
  /* ... */
  .windi-1q7lotv {
    flex-shrink: 0;
    margin-left: 0;
    margin-right: 0;
  }
/* ... */

Interpretation mode

Interpretation mode will not modify your classes, it will only compile the original tailwind classes just like tailwindcss, but it is minimized and has native cross-browser support.

/* ... */
.py-8 {
  padding-top: 2rem;
  padding-bottom: 2rem;
}
/* ... */
@media (min-width: 640px) {
  /* ... */
  .sm\:items-center {
    align-items: center;
  }
  .sm\:mx-0 {
    margin-left: 0;
    margin-right: 0;
  }
  .sm\:py-4 {
    padding-top: 1rem;
    padding-bottom: 1rem;
  }
  /* ... */
}

Using tailwind directives

<style global>
  .testApply {
    @apply pt-6 text-base leading-6 font-bold sm:text-lg sm:leading-7;
  }

  @screen sm {
    ul {
      @apply bg-gray-100 p-2 rounded-lg;
    }
  }
</style>

If you are using Vetur vscode extension, I believe most people are using it. You will need to add "vetur.validation.style": false to your configuration file.

Hit ctrl-shift-p or cmd-shift-p on mac, type open settings, and select Preferences: Open Settings (JSON). Add "vetur.validation.style": false to settings.json then save it.

Features

tw is an optional replacement attribute of class, The className in tw will be merged into the class attribute after compilation.
Group: You can also write groups in all the attributes mentioned above, such as class="font-meidum sm:hover:(font-bold bg-gray-200)". This is a native feature supported by windicss.
Unrestricted build: such as bg-hex-1c1c1e p-3.2 p-3rem p-4px w-10/11 bg-$custom-variable ...
[Using tailwind directives], such as @apply, @screen, @variants.
States attribute: such as sm md lg xl xxl focus hover dark ... after applid media rules then also will be merged into the class attribute. (Attributes like sm:hover are not available because they may be rarely used and slow down the parsing speed.)
Customize: support tailwind.config.js.
