Dual (CommonJS + ESM) Dual package — require() works on every Node.js version we test; import works too

react-hook-form publishes both a CommonJS entry and a native ESM entry (ESM added in 6.9.6). require("react-hook-form") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18.0.0. import "react-hook-form" works alongside it.

What to do

  1. Nothing to change. require("react-hook-form") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=18.0.0. import * as reactHookForm from "react-hook-form" works alongside it; use named imports for what the ESM entry exports.
  2. TypeScript: types are bundled; install nothing extra.
