CommonJS CommonJS on paper — require() failed in our runtime test

vue-loader declares a CommonJS entry only, but require("vue-loader") failed on every Node.js version in our probe: @vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree. import "vue-loader" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

What to do

  1. require("vue-loader") failed in our probe on every Node.js version (@vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree); check the package README for peer dependencies or setup before relying on it.
  2. From ES modules use the default import: import vueLoader from "vue-loader"; then destructure. Named imports only work when Node.js can statically detect the exports.
  3. TypeScript: types are bundled; install nothing extra.

A failing require() on a CommonJS package usually means the package needs a browser/DOM global, a peer dependency, or a native binary that is not available in a bare Node.js process.

How to import vue-loader

ES modules (import)

import vueLoader from "vue-loader";

Named imports from a CommonJS package only work when Node.js can statically detect them. If a named import fails, use the default import and destructure.

CommonJS (require)

// require("vue-loader") failed in our probe on every Node.js version we test (@vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree); see the runtime table.
const vueLoader = require("vue-loader");

Module format by version

Derived from the type, main and exports fields of every stable release on npm, corrected where a runtime test of that version contradicted them (271 versions; the newest 60 shown).

Frequently asked

Is vue-loader ESM-only?

vue-loader@17.4.2 declares a CommonJS entry, but require() fails at runtime. vue-loader declares a CommonJS entry only, but require("vue-loader") failed on every Node.js version in our probe: @vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree. import "vue-loader" resolves to the same file, so it fails the same way. That usually means a missing peer dependency, a browser-only global, or a package that is not meant to be loaded directly; see the runtime table below.

Can I require vue-loader?

Not in practice. vue-loader declares a CommonJS entry, but require("vue-loader") failed on every Node.js version in our probe: @vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree. Check the package README for peer dependencies or setup before relying on it.

Can I import vue-loader with ES module syntax?

Yes. import vueLoader from "vue-loader" works in Node.js and Bun because they support importing CommonJS modules. Named imports work only when Node.js can statically detect the exports.

Does vue-loader work in Bun?

Importing vue-loader failed in Bun 1.4.0 on Sep 9, 2026: error: @vitejs/plugin-vue requires vue (>=3.2.13) or @vue/compiler-sfc to be present in the dependency tree.

Does vue-loader ship TypeScript types?

Yes. vue-loader bundles its own type declarations; no @types package is needed.
