What are eslint-plugin-tailwindcss's main functionalities?

Class Order

This feature ensures that Tailwind CSS classes are ordered correctly. It helps maintain a consistent order of classes, which can improve readability and maintainability.

module.exports = {
  plugins: ['tailwindcss'],
  rules: {
    'tailwindcss/classnames-order': 'warn'
  }
};

No Custom Classnames

This feature disallows the use of custom class names that are not part of the Tailwind CSS framework. It ensures that only Tailwind CSS classes are used, which can help prevent styling issues.

module.exports = {
  plugins: ['tailwindcss'],
  rules: {
    'tailwindcss/no-custom-classname': 'error'
  }
};

No Arbitrary Value

This feature disallows the use of arbitrary values in Tailwind CSS classes. It ensures that only predefined values are used, which can help maintain consistency and prevent errors.

module.exports = {
  plugins: ['tailwindcss'],
  rules: {
    'tailwindcss/no-arbitrary-value': 'error'
  }
};

Installation

You'll first need to install ESLint:

$ npm i eslint --save-dev

Next, install eslint-plugin-tailwindcss:

$ npm install eslint-plugin-tailwindcss --save-dev

Usage

Add tailwindcss to the plugins section of your .eslintrc configuration file. You can omit the eslint-plugin- prefix:

{
    "plugins": [
        "tailwindcss"
    ]
}

Then configure the rules you want to use under the rules section.

{
    "rules": {
        "tailwindcss/classnames-order": 2
    }
}

Supported Rules

• classnames-order: order classnames by target properties then by variants ([size:][theme:][state:])

Upcoming Rules

• no-custom-classname: only allow classnames from Tailwind CSS
• no-contradicting-classname: e.g. avoid p-2 p-3, different Tailwind CSS classnames (pt-2 & pt-3) but targeting the same property
• no-redundant-variant: e.g. avoid mx-5 sm:mx-5, no need to redefine mx in sm: variant as it uses the same value (5)

Alternatives

I wrote this plugin after searching for existing tools which perform the same task but didn't satisfed my needs:

• eslint-plugin-tailwind, not bad but no support (yet) for variants sorting
• Headwind, only works within Visual Studio Code
