Last verified Sep 9, 2026 against normalize-package-data@9.0.0.

normalize-package-data ships CommonJS only. require("normalize-package-data") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0. import "normalize-package-data" 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("normalize-package-data") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js ^22.22.2 || ^24.15.0 || >=26.0.0.
2. From ES modules use the default import: import normalizePackageData from "normalize-package-data"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/normalize-package-data
