process information for node.js and browsers

Last verified Sep 9, 2026 against process@0.11.10.

process ships CommonJS only. require("process") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.6.0. import "process" 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") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 0.6.0.
2. From ES modules use the default import: import process from "process"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: no types are available for process; declare the module yourself if you need them.
