history

Project history and usage

Stylelint is a CSS linter distributed as a command-line and Node.js tool for finding CSS errors and enforcing style conventions. Its official README describes a rule-rich, plugin-capable linter that supports autofix, shareable configs, custom rules, custom syntaxes, and use beside formatters such as Prettier.

Project history

The project reached 1.0.0 on 2015-09-05, when its changelog recorded PostCSS 5 compatibility and line/column accuracy fixes. The current README credits volunteers and identifies David Clark and MoOx among the co-creators, reflecting its evolution from an early PostCSS-era linter into a maintained community project.

Adoption history

Stylelint became package-manager-relevant because it sits directly in frontend build pipelines: it is published as an npm package, is available in Homebrew and Nix according to the input package-manager facts, and its README advertises npm version and download badges. The project also documents migration guides for major releases, including the 16.0.0 migration to ECMAScript modules for plugins, custom syntaxes, formatters, and the Node.js API.

How it is used

Typical use is to add a project config, run the `stylelint` CLI over CSS-like sources, and combine rules, shareable configs, plugins, and custom syntaxes for CSS, SCSS, Less, CSS-in-JS, or related formats. The official docs say Stylelint searches upward from the current working directory for `stylelint.config.js`, with explicit `.mjs`, `.cjs`, `.ts`, `.stylelintrc*`, and `package.json` forms also supported.

Why package nerds care

For package maintainers, Stylelint matters as the CSS-side analogue to JavaScript linters: it has a stable CLI, a shareable-config ecosystem, migration pressure around ESM/CommonJS, and enough package-manager reach that it regularly appears in frontend boilerplates, CI jobs, editor integrations, and Homebrew installs for local tooling.
