# Is redux ESM-only? Can you require() it?

> redux@5.0.1 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

Predictable state container for JavaScript apps

Last verified Sep 9, 2026 against redux@5.0.1.

redux publishes both a CommonJS entry and a native ESM entry (ESM added in 5.0.0). require("redux") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "redux" works alongside it.

## What to do

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