常见的想当然

@babel/preset-env defaults the modules option to commonjs, unconditionally transforming import statements into require calls regardless of caller capabilities.

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

• When the modules option is left unset, @babel/preset-env defaults to 'auto' and preserves static import and export declarations unchanged when caller.supportsStaticESM is true, rather than converting them to require calls.
• When the modules option is left unset with caller.supportsStaticESM set to false, @babel/preset-env transpiles ESM imports into CommonJS require calls and exports.
• Explicitly setting modules to 'commonjs' forces transformation to require calls even when caller.supportsStaticESM is true.
• Explicitly setting modules to false preserves ESM import statements even when caller.supportsStaticESM is false.
