stylelint-browser-compat

Yet another linter rule to detect compatibility of CSS features.

Background

stylelint-no-unsupported-browser-features (using doiuse) is available to detect compatibility of CSS features.

However, doiuse have not been maintained for a long time.

This library provides another alternative to detect compatibility of CSS features.

Although doiuse detects compatibility from caniuse data, this library uses @mdn/browser-compat-data to do so.

Install

$ npm install --dev browserslist stylelint stylelint-browser-compat

$ yarn add --dev browserslist stylelint stylelint-browser-compat

Usage

module.exports = {
  plugins: ['stylelint-browser-compat'],
  rules: {
    'plugin/browser-compat': [
      true,
      {
        allow: {
          features: ['at-rules.supports'],
          flagged: false,
          partialImplementation: false,
          prefix: true,
        },
        browserslist: ['last 2 versions'],
      },
    ],
  },
};

Options

browserslist (string or array, optional)
- Accepts browserslist queries for target browsers.
- By default, browserslist automatically loads the configuration file (e.g. package.json, .browserslistrc).
allow.features (array, optional)
- Accepts an array of features to allow.
- Feature names are from @mdn/browser-compat-data.
  - For example, if you want to use @supports at-rules, pass at-rules.supports.

- false by default
allow.partialImplementation (boolean, optional)
- Allows features that are partial implementations.
- false by default
