常见的想当然

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

这是本样本作者记下的、开发者或模型在此处通常会有的预期。下面的契约才是真正运行过的东西。

契约

• 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
