Last verified Sep 9, 2026 against object-hash@3.0.0.

object-hash ships CommonJS only. require("object-hash") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 6. import "object-hash" 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("object-hash") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >= 6.
2. From ES modules use the default import: import objectHash from "object-hash"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/object-hash
