CommonJS CommonJS — require() works on every Node.js version we test

requirejs ships CommonJS only. require("requirejs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.4.0. import "requirejs" 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("requirejs") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.4.0.
  2. From ES modules use the default import: import requirejs from "requirejs"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: npm install -D @types/requirejs

How to import requirejs

ES modules (import)

import requirejs from "requirejs";

Named imports from a CommonJS package only work when Node.js can statically detect them. If a named import fails, use the default import and destructure.

CommonJS (require)

const requirejs = require("requirejs");

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (52 versions; the newest 52 shown).
