Subject: [PATCH] chore(sw): only proxies HTML requests (#9070)
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
* chore(sw): only proxies HTML requests
もはやHTMLじゃなさそうなリクエストにはSWで関与しないようにする
こうするといろいろな面倒事が解決するはず…たぶん
Resolve #9037
Resolve #9038
* align code style
* Update packages/sw/src/sw.ts
