pnpmはpackage.jsonのscriptsフィールドをどのように処理するのでしょうか。

Hidden Scripts​

Added in: v11.0.0

Scripts with names starting with . are hidden. They cannot be run directly via pnpm run and are omitted from the pnpm run listing. Hidden scripts can only be called from other scripts.

{
  "scripts": {
    ".helper": "echo 'I am hidden'",
    "build": "pnpm run .helper && tsc"
  }
}

In this example, pnpm run .helper would fail, but pnpm run build would succeed because .helper is called from another script.

Environment Variables​

pnpm sets the following environment variables during lifecycle script execution:

  • npm_package_name — the package name
  • npm_package_version — the package version
  • npm_lifecycle_event — the name of the running script (e.g., postinstall)
メモ

Since v11, pnpm no longer populates npm_config_* environment variables from the pnpm configuration. Only the well-known npm_* variables above are set, matching Yarn's behavior.

Built-in Command and Script Name Conflicts​

Added in: v11.0.0

The following built-in commands prefer user scripts: clean, setup, deploy, and rebuild. If your package.json defines a script with one of these names, pnpm <name> will execute the script instead of the built-in command.

To force the built-in command, use pnpm pm <name>.

ライフサイクルスクリプト​

pnpm:devPreinstall​

ローカルマシンでpnpm installを実行するときにだけ実行します。

あらゆる依存関係をインストールする前に実行します。

このスクリプトは、ルートプロジェクトの package.json に設定されている場合にのみ実行します。
