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

url-loader ships CommonJS only. require("url-loader") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 10.13.0. import "url-loader" 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("url-loader") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 10.13.0.
  2. From ES modules use the default import: import urlLoader from "url-loader"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: no types are available for url-loader; declare the module yourself if you need them.
