Last verified Sep 9, 2026 against gulp-cssmin@0.2.0.

gulp-cssmin ships CommonJS only. require("gulp-cssmin") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "gulp-cssmin" also works because Node.js and Bun can import CommonJS from ES modules, but only the default export is guaranteed; named imports depend on Node's static analysis of the module.

## What to do

1. require("gulp-cssmin") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import gulpCssmin from "gulp-cssmin"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for gulp-cssmin; declare the module yourself if you need them.
