Что обычно предполагают
When bundling CommonJS modules that conditionally require Node built-ins into ESM, @rollup/plugin-commonjs preserves lazy evaluation inside functions without hoisting static imports to the module top level.
Автор образца записал здесь то, чего ожидал бы разработчик или модель. Контракт ниже — это то, что действительно выполнялось.
Контракт
- By default, @rollup/plugin-commonjs hoists conditional require('node:fs') calls to top-level ESM static imports, eagerly loading built-in modules on startup rather than preserving lazy CommonJS evaluation.
- Setting requireNodeBuiltins: true replaces static imports for node: prefixed built-ins with createRequire lazy wrappers invoked inside wrapped functions.
- Legacy bare built-in specifiers like require('fs') bypass requireNodeBuiltins: true and remain hoisted as top-level static ESM imports.
- Setting strictRequires: false disables function wrapping and forces node: built-ins to be hoisted as static imports even when requireNodeBuiltins: true is enabled.
