@babel/plugin-syntax-typescript 7.29.7: default

Échantillon vérifié pour npm @babel/plugin-syntax-typescript 7.29.7: default. 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

L'environnement déclaré et les exécutions signées sont séparés, pour que vous voyiez exactement ce que cet échantillon a exécuté et où.

Contrat

  1. Plugin default export is a function factory asserting Babel 7 or 8 compatibility
  2. Plugin factory returns an object named syntax-typescript with a manipulateOptions function
  3. manipulateOptions removes flow and jsx plugins and enables objectRestSpread and classProperties
  4. manipulateOptions enables jsx plugin when isTSX option is true
  5. manipulateOptions does not enable jsx plugin when isTSX option is false or omitted
  6. manipulateOptions appends typescript plugin configuration with disallowAmbiguousJSXLike and dts options
  7. Module helper applyTypeScriptSyntax successfully executes plugin lifecycle and configures parser options

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-syntax-typescript.default in pkg:npm/%40babel/plugin-syntax-typescript@7.29.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40babel/plugin-syntax-typescript@7.29.7
Demonstrate these symbols/APIs:
  - @babel/plugin-syntax-typescript.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.
