html - 如何删除 node_modules 文件夹中不需要的文件 Angular 5

Question

我想删除 node_modules 文件夹中不需要的文件以减小大小和快速加载。我的应用程序在加载时太慢我不知道是什么原因。任何人都可以建议我最小化文件大小。

这是我的package.json

我只希望节点模块中存在依赖文件。

提前致谢。

除非您对自己所做的事情有信心，否则不要触摸 node_modules 文件夹？这是正常的。通常，node_module 文件夹的大小稍大一些。这是因为它包含您正在使用的库及其依赖项以及它们的依赖项。

在这里我可以给出一些建议来减少node_modules文件夹的空间使用

• 尽量使用最新稳定版本的库可能的
• 使用最少数量的库。 (不只是安装没有目的的图书馆)
• 如果仅使用 vanilla javascript 就可以完成任务，则不需要为此使用库。

如果您认为自己通过手动编辑 package.json 文件不小心添加和删除了包。只需删除整个 node_modules 目录并运行 npm install 或 yarn install

虽然 node_module 文件夹的大小很大。它们对性能没有太大影响。在运行时，节点知道要执行什么代码，不执行什么代码。
