Creating a new project with angular cli recently and the node_modules folder was 270 mb, so yes this is normal but I'm sure most new devs to the angular world question this and is valid. For a simple new project it would make sense to pare the dependencies down maybe a bit;) Not knowing what all the packages depend on can be a bit unnerving especially to new devs trying the cli out for the first time. Add to the fact most basic tutorials don't discuss the deployment settings to get the exported files only needed. I don't believe even the tutorial offered on the angular official website talks about how to deploy the simple project.

您的开发配置没有问题。

如果你使用Angular CLI，你可以在创建项目时使用——minimal标志

ng new name --minimal

如果您的文件系统支持符号链接，那么您至少可以将所有这些文件降级到一个隐藏文件夹中——这样像tree这样的智能工具在默认情况下就不会显示它们。

mv node_modules .blergyblerp && ln -s .blergyblerp node_modules

为此使用隐藏文件夹还可以鼓励这样的理解，即这些是与构建相关的中间文件，不需要保存到修订控制中——或者直接在部署中使用。

没什么问题。这些都是您在package.json中提到的所有节点依赖项。

如果你已经下载了一些git hub项目，请小心，它可能有很多其他的依赖关系，而这些依赖关系实际上并不是angular 2 first hello world app所需要的:)

您的配置没有问题。

Angular(从2.0版开始)使用npm模块和依赖项进行开发。这就是你看到这么多文件的唯一原因。

Angular的基本设置包括编译器、类型依赖关系，这些仅用于开发目的。

一旦您完成了开发，您所需要做的就是捆绑这个应用程序。

在捆绑你的应用程序之后，只有一个bundle.js文件可以部署到你的服务器上。

'transpiler'只是一个编译器，感谢@omninonsense添加它。
