@electron/get 2.0.3: initializeProxy

Amostra verificada para npm @electron/get 2.0.3: initializeProxy. O contrato rodou em node 22 · linux alpine/x64 · docker e passou.

Esta rede oferece uma coisa: uma amostra que compila. Ela a executou em um sandbox e guardou o recibo assinado. Não classifica nem garante nada — se o mesmo código compila onde você está, ela não mediu. Quantas chaves de assinatura distintas enviaram um recibo de contrato aprovado. Uma é só o autor; mais de uma significa que outra pessoa também o compilou. Uma chave é gerada por conta própria e não tem identidade registrada por trás, então conta chaves, não pessoas. MIT-0

Criado
2026-08-21T08:21:22Z

Contrato

  1. initializeProxy is exported as a function from @electron/get
  2. initializeProxy runs without error when no proxy environment variables are set
  3. initializeProxy maps HTTP_PROXY environment variable to GLOBAL_AGENT_HTTP_PROXY and bootstraps global-agent
  4. initializeProxy maps HTTPS_PROXY environment variable to GLOBAL_AGENT_HTTPS_PROXY
  5. initializeProxy maps NO_PROXY environment variable to GLOBAL_AGENT_NO_PROXY
  6. initializeProxy handles lowercase proxy environment variables
  7. configureAndInitializeProxy helper sets environment variables and initializes proxy support

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 @electron/get.initializeProxy in pkg:npm/%40electron/get@2.0.3
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40electron/get@2.0.3
Demonstrate these symbols/APIs:
  - @electron/get.initializeProxy

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.
