Install

yarn add windicss-webpack-plugin -D 
# npm i windicss-webpack-plugin -D

webpack.config.js

If you have access to modify the webpack.config.js directly, then you can do the following.

// webpack.config.js
import WebpackWindiCSSPlugin from 'windicss-webpack-plugin'

export default {
  // ...
  plugins: [
    new WebpackWindiCSSPlugin()
  ],
};

// main.js
import 'windi.css'

Other examples

See ./example

That's all. Build your app just like what you would do with Tailwind CSS, but much faster! ⚡️

Migration

If you are already using Tailwind CSS for your app, please consult the documentation on migrating.

All set.

That's all, fire up your app and enjoy the speed!

TypeScript

You can use TypeScript for your config file if you're using esbuild.

Simply rename your config it to tailwind.config.ts.

// tailwind.config.ts
import { defineConfig } from 'windicss-webpack-plugin'

export default defineConfig({
  darkMode: 'class',
  theme: {
    extend: {
      colors: {
        teal: {
          100: '#096',
        },
      },
    },
  },
})

Safelist

By default, we scan your source code statically and find all the usages of the utilities then generated corresponding CSS on-demand. However, there is some limitation that utilities that decided in the runtime can not be matched efficiently, for example

<!-- will not be detected -->
<div className={`p-${size}`}>

For that, you will need to specify the possible combinations in the safelist options of windi.config.ts.

// windi.config.ts
import { defineConfig } from 'windicss-webpack-plugin'

export default defineConfig({
  safelist: 'p-1 p-2 p-3 p-4'
})

Or you can do it this way

// windi.config.ts
import { defineConfig } from 'windicss-webpack-plugin'

function range(size, startAt = 1) {
  return Array.from(Array(size).keys()).map(i => i + startAt);
}

export default defineConfig({
  safelist: [
    range(30).map(i => `p-${i}`), // p-1 to p-3
    range(10).map(i => `mt-${i}`) // mt-1 to mt-10
  ]
})

Scanning

On server start, windicss-webpack-plugin will scan your source code and extract the utilities usages. By default, only files under src/ with extensions vue, html, mdx, pug, jsx, tsx will be included. If you want to enable scanning for other file type of locations, you can configure it via:

// windi.config.js
import { defineConfig } from 'windcss/helpers'

export default defineConfig({
  extract: {
    include: ['src/**/*.{vue,html,jsx,tsx}'],
    exclude: ['node_modules', '.git']
  }
})

Or in plugin options:

// webpack.config.js
import WebpackWindiCSSPlugin from 'windicss-webpack-plugin'

export default {
  // ...
  plugins: [
    new WebpackWindiCSSPlugin({
      scan: {
        dirs: ['.'], // all files in the cwd
        fileExtensions: ['vue', 'js', 'ts'], // also enabled scanning for js/ts
      },
    })
  ],
};
