HOW

Цель: demonstrate ignoreTryCatch behavior for external require calls in @rollup/plugin-commonjs
Пакеты: @rollup/plugin-commonjs 28.0.9
Символы: ignoreTryCatch
Окружение: node 22.23.2
Создан: 2026-09-03T13:22:42Z

Контракт

External require calls inside try-catch blocks are preserved unconverted by default (ignoreTryCatch: true), leaving literal require expressions intact.
Setting ignoreTryCatch: false converts external require calls inside try-catch into hoisted top-level static imports outside the try block.
Setting ignoreTryCatch: 'remove' replaces external require calls inside try-catch blocks with undefined, removing the external dependency entirely.
Setting ignoreTryCatch to an array or filter function enables selective per-module control over which external require calls in try-catch blocks are preserved, converted, or removed.

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: demonstrate ignoreTryCatch behavior for external require calls in @rollup/plugin-commonjs
Kind: HOW

Use EXACTLY these public packages and versions:
  - pkg:npm/%40rollup/plugin-commonjs@28.0.9
Demonstrate these symbols/APIs:
  - ignoreTryCatch

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.
