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

A Webpack Plugin for generating Asset Manifests

Last verified Sep 9, 2026 against webpack-manifest-plugin@6.0.1. JSON

ESM-only ESM-only since 6.0.0 — last CommonJS version is 5.0.1

webpack-manifest-plugin dropped its CommonJS build in 6.0.0 (October 2025). The last version you can require() on every Node.js version, including 18 and older, is 5.0.1, published Mar 11, 2025.

On Node.js 20.19+, 22.12+ and every newer release, require("webpack-manifest-plugin") works anyway: Node can load synchronous ES modules through require(). Verified on Node 20, 22, 24, 26. Node.js 18 and older still fail with ERR_REQUIRE_ESM.

webpack-manifest-plugin@6.0.1 declares engines ">=20.19.0", so Node.js 18 is outside its supported range regardless of module format.
