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

> vuex@4.1.0 ships CommonJS and ESM builds. Dual package — require() works on every Node.js version we test; import works too.

state management for Vue.js

Last verified Sep 9, 2026 against vuex@4.1.0.

vuex publishes both a CommonJS entry and a native ESM entry (ESM added in 3.6.0). require("vuex") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "vuex" works alongside it.

## What to do

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