CommonJS CommonJS — require() works on every Node.js version
react-helmet ships CommonJS only. require("react-helmet") works everywhere. import "react-helmet" 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.
It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.
