常见的想当然

When an ES module imports a CommonJS module that defines exports.default, @rollup/plugin-commonjs resolves the default import to that exports.default value.

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

• Importing a CommonJS module defining exports.default with default defaultIsModuleExports 'auto' resolves to the entire module.exports object rather than exports.default because __esModule is not set.
• CommonJS modules with exports.__esModule true resolve default imports directly to exports.default under defaultIsModuleExports 'auto'.
• Setting defaultIsModuleExports false forces default imports to resolve directly to exports.default even without __esModule.
• Setting defaultIsModuleExports true forces default imports to resolve to module.exports even when exports.__esModule is true.
