概要

株式会社カケハシのTypeScriptに特化したアドベントカレンダーを作りました。

カケハシでは創業期からバックエンドをPython、フロントエンドをTypeScriptを主に選択してきましたが、昨今になって新規事業及び、新規のマイクロサービスを開発をする際にバックエンドTypeScriptも主要な選択肢になっています。

既に4つの開発チームでフルスタックTypeScriptで開発を進めています。
その一部の知見を紹介できればと考えております。

備考

弊社はこのアドベントカレンダーとは別にカケハシ Advent Calendar 2021も進めております。
こちらはエンジニア職に限定せずにカケハシのプロダクト開発にまつわる様々な業務内容の紹介をしている関係で、Adventarのサービスを利用しています。
