<div data-backgroundColor="white">
  <h1 data-color="gray.900">attrCSS</h1>
</div>

Usage

This command generates an attr.css file that can be used in your project:

npx attrcss build

Import the generated CSS file in your project, and start using data attributes:

<div data-backgroundColor="white">
  <h1 data-color="gray.900">attrCSS</h1>
</div>

Install

# yarn
yarn add -D attrcss

# npm
npm i -D attrcss

Then run it using attrcss build.

Options

-i, --input

Specify a custom .json theme file. Your theme will be merged with the default one.

It must follow this structure:

{
  "prefix": "",
  "separator": ".",
  "theme": {
    "something": {
      "extend": ["colors", "spacing", "-spacing"],
      "alias": ["someone"],
      "valueName1": "value",
      "valueName2": "value"
    }
  },
  "variants": {}
}

• prefix: inserted after data-
• separator: used for nested values, like gray.900
• something: a valid css property. Use either kebab case or camel case
• extend: automatically extends this property with theme colors or spacing. "-spacing" results in negative values.
• alias: alternative name for something. Will be used for creating data properties.
• valueName: possible values.
• variants: can be responsive or any other CSS pseudo class.

-o, --output

You can specify a custom output file here. It must be a CSS file.

PS. Use PurgeCSS!

PPS. This is functional, but I never tried it in production. 🦦

PPPS. The code is a bit messy. I was kinda bored ._.
