stylelint-webpack-plugin

A webpack plugin that runs Stylelint during the build process to lint CSS, SCSS, SASS, and other style files. Current stable version is 5.1.0, released February 2026. Supports webpack 5 only (for webpack 4, use the 2.x branch). Peer dependencies require Stylelint >=13 up to 17, and Node.js >=18.12.0 (v5 breaking change). Key differentiators: integrates linting directly into webpack compilation, supports caching (enabled by default since v4.1.1), autofixing, and custom formatters. Ships TypeScript types. Alternative to running Stylelint as a separate process or using other linting plugins like eslint-webpack-plugin for styles.
