    ベータ機能の Unit 既存の Controller のコード " # Chanko では、Unit というファイルにベータ機能のロジックを記述する

    invoke 条件を満たした場合に、既存ロジック (A) の代わりに Unit (B) が実行される B が例外を起こした場合は、元の A が実行されるため、ユーザにはエラーが返らない JOWPLF৚݅

    Chanko • 既存のコードをほぼ汚さずに機能の置 き換え実験ができる(Chanko Unit) • もし Unit 内で例外が起きたら、既存の コードが実行される

    • Chanko Unit は汚く書いてもいいけ ど、Un-chanko 時にはリファクタリン グしようね、という運用
