爲什麼Gulp在重新啓動Angular服務器時還原所有更改？

Question

我有一個帶有/ dev和/ dist目錄的Angular項目。我在/ dev中完成了所有的開發工作。但是，無論何時我需要重新啓動服務器，我都會丟失我所做的所有更改（index.html，控制器等）。因此，現在唯一的解決方案是嘗試保留freshet備份副本並在發生時將其粘貼回去。任何想法爲什麼發生這種情況？

Answer 1

只是看着你gulp config和接縫像你運行gulp serve後，你必須在你的code/modify所以public什麼時候是它它得到複製到devpublic文件夾中得到改變和dist文件夾。

你browserSync期待中dev文件夾，當你運行gulp serve所以它總是與你的public文件夾同步。基本上dev和dist總是根據public中的內容自動生成。

dist總是擁有所有資產並且可以在服務器上部署。
