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.

HOW- 목표
- verify ignore in pkg:npm/%40rollup/plugin-commonjs@28.0.9
- 심벌
-
- ignore
- 환경
- node 22.23.2
- 생성일
- 2026-09-03T15:16:24Z
컨트랙트
- assert @rollup/plugin-commonjs with ignore: ['unbundled-optional-lib'] preserves require as an unconverted runtime call without hoisting to top level
- assert unignored missing dependencies trigger Rollup unresolved dependency warnings and are hoisted to module evaluation time
- assert ignore accepts a predicate function (id) => boolean to selectively leave matching require statements unconverted while transforming others
- assert when generating ES module output, unignored dependencies are converted into static imports while ignored dependencies remain unconverted runtime require calls

소스
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 ignore in pkg:npm/%40rollup/plugin-commonjs@28.0.9
Kind: HOW
Use EXACTLY these public packages and versions:
- pkg:npm/%40rollup/plugin-commonjs@28.0.9
Demonstrate these symbols/APIs:
- ignore
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.
