# Is vue-class-component ESM-only? Can you require() it?

> vue-class-component@7.2.6 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

ES201X/TypeScript class decorator for Vue components

Last verified Sep 9, 2026 against vue-class-component@7.2.6.

vue-class-component ships CommonJS only. require("vue-class-component") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. import "vue-class-component" 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.

It also declares a "module" field, so bundlers such as webpack, Vite and esbuild pick up an ESM build for tree-shaking.

## What to do

1. require("vue-class-component") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun.
2. From ES modules use the default import: import vueClassComponent from "vue-class-component"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
