an identity object using ES6 proxies

Last verified Sep 9, 2026 against identity-obj-proxy@3.0.0.

identity-obj-proxy ships CommonJS only. require("identity-obj-proxy") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=4. import "identity-obj-proxy" 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("identity-obj-proxy") 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 identityObjProxy from "identity-obj-proxy"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: npm install -D @types/identity-obj-proxy
