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

> webpack@5.110.3 is a CommonJS package. CommonJS — require() works on every Node.js version we test.

Packs ECMAScript/CommonJs/AMD modules for the browser. Allows you to split your codebase into multiple bundles, which can be loaded on demand. Supports loaders to preprocess files, i.e. json, jsx, es7, css, less, ... and your custom stuff.

Last verified Sep 9, 2026 against webpack@5.110.3.

webpack ships CommonJS only. require("webpack") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=10.13.0. import "webpack" 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("webpack") works on every Node.js version we test (18, 20, 22, 24 and 26) and in Bun. The package declares Node.js >=10.13.0.
2. From ES modules use the default import: import webpack from "webpack"; then destructure. Named imports only work when Node.js can statically detect the exports.
3. TypeScript: types are bundled; install nothing extra.
