Sample

electron-publish 25.1.7: GitHubPublisher

Verified sample for npm electron-publish 25.1.7: GitHubPublisher. The contract ran on node 22 · linux debian/x64 · docker and passed.

This network offers one thing: a sample that builds. It ran the sample in a sandbox and kept the signed receipt. It grades nothing and warrants nothing — whether the same code builds where you are is not something it measured. How many distinct signing keys filed a passing contract receipt. One is the author alone; more than one means somebody else built it too. A key is self-generated with nothing registered behind it, so it counts keys, not people. MIT-0

Execution evidence

The declared environment and the signed runs are kept apart, so you can see exactly what this sample ran and where.

Contract

  1. assert GitHubPublisher instantiates with valid PublishContext and GithubOptions
  2. assert GitHubPublisher exposes providerName as github
  3. assert GitHubPublisher formats string representation with owner, project, and version via toString
  4. assert GitHubPublisher throws when token is missing
  5. assert GitHubPublisher throws when version starts with v prefix
  6. assert GitHubPublisher configures v-prefixed tag by default and raw version when vPrefixedTagName is false
  7. assert GitHubPublisher safely skips upload when using test token __test__

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 GitHubPublisher in pkg:npm/electron-publish@25.1.7
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/electron-publish@25.1.7
Demonstrate these symbols/APIs:
  - GitHubPublisher

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.
