Heroku Ruby/RailsキャッシュWebpack +デプロイ間の糸

Question

私は現在、webpackerで全く新しいruby/railsアプリケーションの設定をしています。 Herokuに展開するたびに、糸の依存関係を再インストールするのに30秒以上かかる（実行はyarn install）。

私は現在、heroku-16スタックにheroku/ruby buildpackを使用しています。 キャッシュをbundlerのように動作させる簡単な方法はありますか？

Answer 1

たぶん、あなたはあなたのHerokuのスタックに加えて、a second nodejs buildpackを追加することができます。

heroku buildpacks:add --index 1 heroku/nodejs 

hereが説明したようnodejs buildpackは、糸のキャッシングをサポートする必要があります。
