Last verified Sep 9, 2026 against compression-webpack-plugin@12.0.0.

compression-webpack-plugin ships CommonJS only. require("compression-webpack-plugin") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 20.9.0. import "compression-webpack-plugin" 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("compression-webpack-plugin") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 20.9.0.
