Setting compilerOptions.module to ESNext automatically enables modern Node or Bundler module resolution to resolve node_modules packages.

이 샘플의 작성자가 여기서 개발자나 모델이 기대할 법한 내용으로 적어둔 것이다. 아래 계약이 실제로 실행된 것이다.

When compilerOptions.moduleResolution is omitted, compilerOptions.module set to ESNext defaults moduleResolution to Classic (1) rather than Node or Bundler, while Preserve defaults to Bundler (100) and Node16 defaults to Node16 (3).
compilerOptions.moduleResolution set to Bundler accepts extensionless relative imports and directory index imports in ESM contexts
compilerOptions.moduleResolution set to Node16 and NodeNext rejects extensionless relative imports with TS2835 and directory imports with TS2834
relative .js specifiers resolve to underlying .ts source files across Node16, NodeNext, and Bundler moduleResolution modes
direct .ts extension imports require allowImportingTsExtensions and otherwise fail with TS5097
Node16 moduleResolution selects import or require package export conditions based on importer format, whereas Bundler defaults to import
Node16, NodeNext, and Bundler moduleResolution enforce package exports encapsulation with TS2307, whereas legacy Node10 ignores exports maps
Bundler moduleResolution respects customConditions compiler option to resolve matching conditional package exports
