推荐答案

的 node_modules 目录仅适用的构建工具的

在应用程序根目录的的package.json 文件定义了库将被安装到 node_modules 当您运行 NPM安装。

The package.json file in the app root defines what libraries will be installed into node_modules when you run npm install.

很多时候带有棱角的应用程序，在您的开发计算机或生成服务器上，您使用来自NPM其他JavaScript库（一个Node.js的包管理器），以建立自己的角度应用程序。任务可以串联的资源，使用CSS preprocessors一样都不能少或SASS，缩小，价值观等，等，为管理和运行这些任务的最常用的工具的替换被称为的咕噜和一饮而尽的，它们通过NPM安装好了。

Very often with an angular app, on your dev machine or on a build server, you use other Javascript libraries from npm (a node.js package manager) to build your angular app. Tasks can be concatenating resources, using CSS preprocessors like LESS or SASS, minification, replacing of values, etc. etc. The most common tools for managing and running these tasks are called grunt and gulp, which are installed through npm as well.

在部署应用程序，你只发布最终版本，没有任何一个源文件或创建工具。

When you deploy your app, you only distribute the resulting build, not any of the source files or build tools.

这当然是可以编写应用程序AngularJS没有任何建设

It is of course possible to write an AngularJS app without building anything.

从评论编辑：当你潜入角多，有即使在客户端应用程序通过使用安装NPM库更先进的技术，你再有选择性地选择你需要的那些，而不是整个50MB +事情。我建议的基本途径住，直到你在他们身上得到了很好的把握，虽然。

edit from comments: When you dive into Angular more, there are more advanced techniques of using libraries installed by npm even in the client app, you then selectively choose the ones you need, not the whole 50MB+ thing. I'd recommend staying with the basic approaches until you get a good grasp on them though.
