Last verified Sep 9, 2026 against npm-run-all@4.1.5.

npm-run-all ships CommonJS only. require("npm-run-all") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 4. import "npm-run-all" 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("npm-run-all") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 4.
2. From ES modules use the default import: import npmRunAll from "npm-run-all"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for npm-run-all; declare the module yourself if you need them.
