# Is ncp ESM-only? Can you require() it?

> ncp@2.0.0 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

Asynchronous recursive file copy utility.

Last verified Sep 9, 2026 against ncp@2.0.0.

ncp ships CommonJS only. require("ncp") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "ncp" 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("ncp") 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 ncp from "ncp"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/ncp
