A collection of SCSS-specific rules for Stylelint

Last verified Sep 9, 2026 against stylelint-scss@7.2.0.

stylelint-scss dropped its CommonJS build in 7.0.0 (January 2026). The last version with a plain require()-able CommonJS entry is 6.14.0, published Dec 28, 2025; it declares support for Node.js >=18.12.0.

On Node.js 20.19+, 22.12+ and newer, require("stylelint-scss") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26. Node.js 18 has no require(esm), and stylelint-scss@7.2.0 declares Node.js >=20.19.0, so 18 is outside its supported range anyway.

stylelint-scss@7.2.0 declares engines ">=20.19.0", so Node.js 18 is outside its supported range regardless of module format.

## What to do

1. On Node.js 20.19+, 22.12+ and newer, require("stylelint-scss") works with the latest version: Node.js loads synchronous ES modules through require(). Verified on Node.js 20, 22, 24 and 26.
2. From a CommonJS file, use a dynamic import inside an async function: const stylelintScss = await import("stylelint-scss"). That works on every Node.js version the package supports (>=20.19.0).
3. If you need a synchronous require() or run Node.js 18: npm install stylelint-scss@6.14.0, the last CommonJS release (published Dec 28, 2025); it declares Node.js >=18.12.0.
4. stylelint-scss@7.2.0 declares engines ">=20.19.0", so Node.js 18 is unsupported regardless: upgrade Node.js or pin an older release.
5. TypeScript: no types are available for stylelint-scss; declare the module yourself if you need them.
