Häufige Annahme

By default @rollup/plugin-commonjs transforms require expressions into bundled module imports in any file processed by Rollup.

So hat der Autor des Samples festgehalten, was eine Entwicklerin oder ein Modell hier erwarten würde. Der Vertrag darunter ist das, was tatsächlich lief.

Contract

• assert @rollup/plugin-commonjs without transformMixedEsModules leaves require calls untransformed in files containing ES imports, producing runtime ReferenceError in ESM output
• assert transformMixedEsModules: true converts require calls into bundled CommonJS helper invocations in mixed ESM/CJS files
• assert requireReturnsDefault defaults to false, returning an augmented namespace object with __esModule marker rather than unwrapping default export directly when CJS requires ESM
• assert requireReturnsDefault: 'auto' unwraps the default export directly when an ES module has no named exports, but returns the namespace object if named exports are present
