为什么Gulp在重新启动Angular服务器时还原所有更改？

Question

我有一个带有/ dev和/ dist目录的Angular项目。我在/ dev中完成了所有的开发工作。但是，无论何时我需要重新启动服务器，我都会丢失我所做的所有更改（index.html，控制器等）。因此，现在唯一的解决方案是尝试保留freshet备份副本并在发生时将其粘贴回去。任何想法为什么发生这种情况？

Answer 1

只是看着你gulp config和接缝像你运行gulp serve后，你必须在你的code/modify所以public什么时候是它它得到复制到devpublic文件夹中得到改变和dist文件夹。

你browserSync期待中dev文件夹，当你运行gulp serve所以它总是与你的public文件夹同步。基本上dev和dist总是根据public中的内容自动生成。

dist总是拥有所有资产并且可以在服务器上部署。
