Stylelint

Stylelint is a CSS linting tool.

Probably worth checking to see first if there is a specific ESLint tool to achieve what you want with this. Here's an example for @emotion

Getting started

Initialise your stylelint config with:

npm init stylelint

Optionally, you may want to rename the default JSON config to MJS:

// This is the default config, but in JS.
const config = {
  extends: ['stylelint-config-standard'],
};

export default config;

See Getting started | Stylelint

After this, add .stylelintcache/ to your .gitignore.
