ニコニコ生放送のアプリケーションにRspackを導入している話
この記事はニコニコ生放送のフロントエンドのアプリケーションにRspackを導入にあたって直面した問題やその解決策について時系列でまとめたものです。 以前書いた既存のアプリケーションに Rspack を導入しようとして失敗した話の記事と重複するところもありますが、記事を書いた時点では達成できなかった本番環境での実践投入を果たすにあたって新たな試行錯誤もあったのでリライトという形で本記事を書いています。 why Rspack? ニコニコ生放送のフロントエンドではWebpackを利用して成果物を生成しているのですが、ビルドの遅さによって開発体験が悪化しており、その改善策を模索していました。 問題の改善策として、以前にViteを導入することで開発時のビルド速度の改善を試みたことがあったのですが、css modulesのcomposesという機能で読み込んだscssがcssとして取り扱われてしまう問

webpack to Rspack ~ Rspack移行の結果と注意点 ~
プロダクトのビルドツールを webpack から Rspack に移行したので、その経緯と注意点をまとめます。 🦀 Rspackとは？ Rustで書かれた高速なJavaScriptのバンドルツールです。 webpackエコシステムとの強力な互換性を持ちます。 2024/08/24にv1.0.0がリリースされました。 🤔 なぜRspackに移行したのか？ ビルド速度改善のため以前からwebpackの移行を検討していましたが、プロダクトがwebpack依存の構成[1]で、Viteやその他のビルドツールへの移行が少し面倒でした。 Rspackであればwebpackのプラグインもそのまま動き移行が容易、かつ速度改善が見込まれるためRspackへの移行を選びました。 💡 移行方法 移行方法は、rspackの公式ドキュメントの migrate from webpack をそのまま参考にして進めま
