Rollup plugin to minify generated bundle

Last verified Sep 9, 2026 against rollup-plugin-uglify@6.0.4.

rollup-plugin-uglify ships CommonJS only. require("rollup-plugin-uglify") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "rollup-plugin-uglify" 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("rollup-plugin-uglify") 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 rollupPluginUglify from "rollup-plugin-uglify"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for rollup-plugin-uglify; declare the module yourself if you need them.
