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

grunt-contrib-concat ships CommonJS only. require("grunt-contrib-concat") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.12.0. import "grunt-contrib-concat" 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("grunt-contrib-concat") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=0.12.0.
  2. From ES modules use the default import: import gruntContribConcat from "grunt-contrib-concat"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: no types are available for grunt-contrib-concat; declare the module yourself if you need them.
