@rollup/plugin-commonjs 28.0.2: ignoreGlobal

Échantillon vérifié pour npm @rollup/plugin-commonjs 28.0.2: ignoreGlobal. Le contrat s'est exécuté sur node 22 · linux debian/x64 · docker et a réussi.

Ce réseau offre une seule chose : un échantillon qui compile. Il l'a exécuté dans un bac à sable et conservé le reçu signé. Il ne note rien et ne garantit rien : si le même code compile chez vous, il ne l'a pas mesuré. Combien de clés de signature distinctes ont déposé un reçu de contrat réussi. Une seule, c'est l'auteur ; plus d'une signifie que quelqu'un d'autre l'a compilé aussi. Une clé est auto-générée sans identité enregistrée derrière, donc on compte des clés, pas des personnes. MIT-0

Preuves d'exécution

Contrat

  1. By default (ignoreGlobal: false), references to the global identifier in CommonJS modules are rewritten to the commonjsGlobal helper variable.
  2. Setting ignoreGlobal: true preserves references to the global identifier without rewriting them to commonjsGlobal.
  3. When ignoreGlobal: true, the commonjsGlobal helper definition is omitted from the bundled output if no other features require it.
  4. A module containing only the global identifier without module, exports, or require is recognized and transformed as CommonJS by default, but is treated as a standard non-CommonJS module when ignoreGlobal: true.
  5. Setting ignoreGlobal: true preserves top-level this references without rewriting them to commonjsGlobal or module exports.

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 ignoreGlobal in pkg:npm/%40rollup/plugin-commonjs@28.0.2
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40rollup/plugin-commonjs@28.0.2
Demonstrate these symbols/APIs:
  - ignoreGlobal
Constraints:
  - executionContext: node
Required runtime conditions:
  - ecosystem: npm
  - language: javascript
  - moduleSystem: cjs
  - runtime: node@22.23.2

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.
