node.js - What are the benefits of installing Express.js locally vs globally

Question

As I understand it, there are two ways to install Express.js.

1. Using npm install express - either from package.json or via command line. This method will install express locally in your node_modules folder.
2. Using npm install express -g . This method installs the package globally on your machine.

I was just wondering what the benefits were to using either method. Is either one considered "best practice" over the other?

Answer 1

要创建应用程序，您应该始终在本地安装它。这将允许您为您制作的每个应用程序使用不同的 express 版本。

全局安装 express 将允许您使用express命令行实用程序来创建样板代码和东西。所以理想情况下，你应该在两个地方都安装 express，但要确保你开发的应用程序在本地版本上运行。
