Generate css from text files that containing windi classes.
By default, it will use interpretation mode to generate a single css file.

  -c, --compile         Compilation mode, combine the class name in each row into a single class.

Initial Test Project

windicss --init <project>  // windicss --init .
windicss --init <project> --compile  // windicss --init hello_world --compile

File Names

The [filenames] parameter can include filepaths and glob patterns(powerd by node-glob).

windicss './hello.html' './world.html'
windicss './**/*.html'
windicss './src/**/*.html'
windicss './hello.html' './world.html', './src/**/*.svelte'

Compile CSS File

Generate normal css

Use the -o parameter to specify the name of the generated CSS file, and the -t parameter to specify whether to add preflight (basestyles).

windicss './**/*.html'
windicss './**/*.html' -to windi.css
windicss './test.html' -to windi.css
windicss './test.html' --preflight --output windi.css

Minimize build

Use -m or --minify to generate minimized CSS file. This parameter is mostly used for build time.

windicss './**/*.html' -mto windi.min.css
windicss './**/*.html' -to windi.css --minify

Using compilation mode

Compilation mode will combine all windi utilities into a new class, which you can specify with -p or --prefix

windicss './**/*.html' -cto windi.css
windicss './**/*.html' -ctom windi.min.css
windicss './**/*.html' -cto windi.css --minify
windicss './**/*.html' -cto windi.css --minify --prefix 'tw-'
windicss './test.html' --compile --preflight --output windi.css

Give an example

<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>

Using attributify mode

You can combine attributify mode with interpretation mode or compilation mode.

windicss './**/*.html' -ato windi.css
windicss './**/*.html' -atom windi.min.css
windicss './**/*.html' -ato windi.css --minify
windicss './test.html' --attributify --preflight --output windi.css
windicss './test.html' --attributify --compile --preflight --output windi.css

Give an example

<button
  bg="blue-400 hover:blue-500 dark:blue-500 dark:hover:blue-600"
  text="sm white"
  font="mono light"
  p="y-2 x-4"
  border="2 rounded blue-200"
>
  Button
</button>

Pass a config file

Pass a configuration file with the -f or --config parameter, currently only js configuration files are supported.

windicss './**/*.html' -to windi.css --config windi.config.js

Give an example

windi.config.js
module.exports = {
  // ...
  theme: {
    extend: {
      colors: {
        primary: '#1c1c1e',
      },
      // ...
    },
  },
}

Dev mode

Development mode will turn on hot reloading and will watch your file changes to update your CSS file in real time.

windicss './**/*.html' -to windi.css --dev

Note: For better hotloading experience (~5ms) we don't remove built CSS at development time, so you are expected to rebuild it once at release time using the minimize command to get the best experience for both development and build. Such as windicss './**/*.html' -mto windi.css

Fuzzy mode

By default windi matches class/className='...' in the incoming files, if your file type doesn't match, you can turn this option on. It will match all possible windi utilities contained in the file

windicss './**/*.html' -to windi.css --dev --fuzzy

You can also configure extractors for specific file types

windi.config.js
module.exports = {
  // ...
  extract: {
    extractors: [
      {
        extractor: (content) => {
          return { classes: content.match(/(?<=class:)[!@\w-]+/g) ?? [] }
        },
        extensions: ['svelte'],
      },
    ],
  },
  // ...
}

Style block

To enable style block, you need to use --style arg.

windicss './**/*.html' -to windi.css --dev --style

Define style block like this:

<head>
  <meta charset="UTF-8">
  <meta name="viewport" content="width=device-width, initial-scale=1.0">
  <title>cli</title>
  <link rel="stylesheet" href="windi.css">
  <style lang='windi'>
    .btn-blue {
      @apply bg-blue-500 hover:bg-blue-700 text-white;
      padding-top: 1rem;
    }
  </style>
</head>
