이 네트워크가 제공하는 것은 하나입니다. 빌드되는 샘플. 샌드박스에서 돌리고 서명된 영수증을 보관합니다. 등급을 매기지 않고 무엇도 보증하지 않습니다 — 같은 코드가 당신 환경에서 빌드되는지는 측정한 적이 없습니다. 통과한 계약 영수증을 낸 서로 다른 서명 키의 수입니다. 하나면 작성자 혼자이고, 둘 이상이면 다른 사람도 빌드했다는 뜻입니다. 키는 스스로 만드는 것이고 뒤에 등록된 신원이 없으므로, 세는 것은 사람이 아니라 키입니다. MIT-0

컨트랙트

  1. Default export resolves to a plugin factory function asserting Babel version 7
  2. Plugin factory returns a plugin object named transform-modules-commonjs with a Program visitor
  3. Transforms ES named import and export declarations into CommonJS require and exports
  4. Transforms default import and default export declarations with interop helper
  5. Transforms namespace wildcard imports with interop wildcard helper
  6. Transforms re-export named and re-export star declarations into dynamic getters on exports
  7. Transforms side-effect only imports into bare require calls
  8. Transforms dynamic import expressions when proposal flag is active
  9. Emits lazy loading wrapper functions when lazy option is enabled
  10. Emits simple assignment exports and __esModule flag when loose option is true
  11. Omits use strict directive when strictMode option is false
  12. Omits __esModule export definition when strict option is true
  13. Imports default export without interop helper when noInterop option is true
  14. Supports custom module wrapper hooks registered via defineCommonJSHook
  15. Configures import interop strategy via importInterop option

Clean-room public code sample — generation instructions

Write a brand-new, minimal, self-contained code sample in this clean-room directory.
Do not copy, paraphrase, or reference any existing project source. Work only from this spec.

A csx.json manifest scaffold already exists. Do not recreate it from memory. Preserve its case.goal, packages and symbols; fill its empty case.contract with exact assertions and correct its environment, commands and verifierAdapter for the files you generate.

Goal: verify @babel/plugin-transform-modules-commonjs.default in pkg:npm/%40babel/plugin-transform-modules-commonjs@7.29.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/plugin-transform-modules-commonjs@7.29.7
Demonstrate these symbols/APIs:
  - @babel/plugin-transform-modules-commonjs.default

Rules:
  - One focused purpose; the smallest project that proves the goal.
  - Include a contract test (test/contract.*) that runs OFFLINE and exits 0 exactly when the goal behavior works.
  - Pin every dependency with a lockfile so resolution is reproducible.
  - No secrets, credentials, or tokens. No real URLs (only example.com or localhost). No absolute paths.
  - No personal names, emails, company names, or project identifiers of any kind.
  - No binaries and no generated output (node_modules, dist, target, venv, .git, .env).
  - Keep it under 200 files and 256KB packed.
