Last verified Sep 9, 2026 against @nodelib/fs.scandir@4.0.1.

@nodelib/fs.scandir ships CommonJS only. require("@nodelib/fs.scandir") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18.18.0. import "@nodelib/fs.scandir" 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("@nodelib/fs.scandir") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18.18.0.
2. From ES modules use the default import: import fsScandir from "@nodelib/fs.scandir"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
