generate-tailwindcss-safelist v1.0.3

npx generate-tailwindcss-safelist

A tool to scan a project for Tailwind CSS classnames and generate a JSON safelist file. This is particularly useful when creating a UI library where you want to export a list of all used Tailwind classes. Consumers of your library can then import this safelist in their tailwind.config.js to ensure these classes are included in the final CSS output.

Usage

To generate a safelist of Tailwind classnames used in your project, run:

npx generate-tailwindcss-safelist -i <path-to-input-css> -o <path-to-output-json>

Parameters

• -i (required): The location of the CSS file Tailwind should process, containing your @tailwind directives.
• -o (required): Output location for the generated JSON safelist file.

Examples

Basic Usage

npx generate-tailwindcss-safelist -i ./src/styles.css -o safelist.json

Given an input CSS file, src/styles.css:

@tailwind components;
@tailwind utilities;

This will generate safelist.json:

["sr-only", "fixed", "absolute", "relative", "flex", "max-h-[300px]"]

Example for End Users

For users of your package, here’s how they can import the generated safelist in their Tailwind configuration:

// tailwind.config.js
import twSafelist from '<package-name>/safelist.json';

const config = {
  safelist: twSafelist,
  // ...rest of the Tailwind config
};

export default config;
