Last verified Sep 9, 2026 against process-nextick-args@2.0.1.

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