Stylelint

npm version Build Status npm downloads

A mighty CSS linter that helps you avoid errors and enforce conventions.

Features

It's mighty as it:

  • has over 100 built-in rules for modern CSS syntax and features
  • supports plugins so you can create your own custom rules
  • automatically fixes problems where possible
  • supports shareable configs that you can create or extend
  • can be customized to your exact needs
  • has 15k unit tests making it robust
  • is trusted by companies worldwide like Google and GitHub

And it can be extended to:

  • extract embedded styles from HTML, Markdown and CSS-in-JS template literals
  • parse CSS-like languages like SCSS, Sass, Less and SugarSS

How it'll help you

It'll help you avoid errors, for example:

  • invalid things, e.g. malformed grid areas
  • valid things that are problematic, e.g. duplicate selectors
  • unknown things, e.g. misspelled property names

And enforce conventions, for example:

  • disallow things, e.g. specific units
  • enforce naming patterns, e.g. for custom properties
  • set limits, e.g. the number of ID selectors
  • specify notations, e.g. for modern color functions

We recommend using a pretty printer like Prettier alongside Stylelint. Linters and pretty printers are complementary tools that work together to help you write consistent and error-free code.
