Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

@rollup/plugin-commonjs publishes both a CommonJS entry and a native ESM entry (ESM added in 22.0.0). require("@rollup/plugin-commonjs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=16.0.0 || 14 >= 14.17. import "@rollup/plugin-commonjs" works alongside it.

What to do

  1. Nothing to change. require("@rollup/plugin-commonjs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=16.0.0 || 14 >= 14.17. import * as pluginCommonjs from "@rollup/plugin-commonjs" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
