Style Dictionary Tailwind CSS Transformer

This is a plugin to generate the config of Tailwind CSS using Style Dictionary.

Install

$ npm install sd-tailwindcss-transformer
# or with yarn
$ yarn add sd-tailwindcss-transformer

Usage

Creating configuration file

Generate tailwind.config.js by setting type to all. See Creating each theme file if you wish to customize the configuration file with plugin functions, etc.

import StyleDictionary from 'style-dictionary';
import { makeSdTailwindConfig } from 'sd-tailwindcss-transformer';

const styleDictionaryTailwind = new StyleDictionary(
    makeSdTailwindConfig({ type: 'all' }),
);
await styleDictionaryTailwind.hasInitialized;
await styleDictionaryTailwind.buildAllPlatforms();

Output:

// tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  mode: "jit",
  content: ["./src/**/*.{ts,tsx}"],
  darkMode: "class",
  theme: {
    extend: {
      colors: {
        base: {
          gray: "#111111",
          red: "#FF0000",
          ...
        }
      },
      fontSize: {
        small: "0.75rem",
        medium: "1rem",
        ...
      }
    },
  }
}

Creating each theme file

Create an object for each theme, assuming that various customizations will be made in the configuration file. Import and use the created files in tailwind.config.js.

import StyleDictionary from 'style-dictionary';
import { makeSdTailwindConfig } from 'sd-tailwindcss-transformer';

const types = ['colors', 'fontSize'];

for (const type of types) {
    let tailwindConfig = makeSdTailwindConfig({
        type,
    });

    const styleDictionaryTailwind = new StyleDictionary(tailwindConfig);

    await styleDictionaryTailwind.hasInitialized;
    await styleDictionaryTailwind.buildAllPlatforms();
}

Output:

/// colors.tailwind.js
module.exports = {
  base: {
    gray: "#111111",
    red: "#FF0000",
    ...
  }
}

/// fontSize.tailwind.js
module.exports = {
  small: "0.75rem",
  medium: "1rem",
  ...
}

Using CSS custom variables

CSS custom variables can be used by setting isVariables to true. In this case, a CSS file must also be generated.

import StyleDictionary from 'style-dictionary';
import { makeSdTailwindConfig } from 'sd-tailwindcss-transformer';

const sdConfig = makeSdTailwindConfig({
    type: 'all',
    isVariables: true,
});

sdConfig.platforms['css'] = {
    transformGroup: 'css',
    buildPath: './styles/',
    files: [
        {
            destination: 'tailwind.css',
            format: 'css/variables',
            options: {
                outputReferences: true,
            },
        },
    ],
};

const styleDictionaryTailwind = new StyleDictionary(
    makeSdTailwindConfig({ type: 'all' }),
);
await styleDictionaryTailwind.hasInitialized;
await styleDictionaryTailwind.buildAllPlatforms();

Output:

/* tailwind.css */
/**
 * Do not edit directly
 * Generated on ○○○○
 */

:root {
  --font-size-medium: 1rem;
  --font-size-small: 0.75rem;
  --colors-base-red: #ff0000;
  --colors-base-gray: #111111;
  ...;
}

// tailwind.config.js
/** @type {import('tailwindcss').Config} */
module.exports = {
  mode: "jit",
  content: ["./src/**/*.{ts,tsx}"],
  darkMode: "class",
  theme: {
    extend: {
      colors: {
        base: {
          gray: "var(--colors-base-gray)",
          red: "var(--colors-base-red)",
          ...
        }
      },
      fontSize: {
        small: "var(--font-size-small)",
        medium: "var(--font-size-medium)",
        ...
      }
    },
  }
}
