CommonJSからES Modulesへの移行する方法。トップダウンかボトムアップか
Secretlint v7でCommonJS からES Modulesへの移行を行いました。 Secretlint v7.0.0をリリースしました。Pure ESMへの書き直し この記事では、CommonJS(CJS)からES Modules(ESM)への移行を行った経緯と、移行する方法について紹介します。 CJSからESMへの移行は、率直に言えば単調な作業で、メリットが見えにくい作業です。 しかし、将来的にCJSよりもESMが主流になることは間違いないので、移行することは必要です。 移行の作業は、移行方法が決まれば大部分は機械的な書き換えが可能です。 では、実際にどうやって移行したのかを紹介します。 ESMへの移行の影響は依存元へと連鎖する Secretlintのリポジトリはmonorepoになっていて、だいたい40コぐらいのパッケージが含まれています。 そしてパッケージ間で依存関係があ
