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

isexe publishes both a CommonJS entry and a native ESM entry (ESM added in 3.0.0). require("isexe") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=20. import "isexe" works alongside it.

What to do

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