Start creating a node.js project

1. You need to install express
   , a node.js development framework, and check the following information. This framework is not an encapsulation of node.js, but an extension of web applications for node.js (official website http://www.expressjs. com.cn/ )
   
   Node's new framework is all done through npm (package manager), and the new node installation file comes with npm.
   Installation command
   Non-global installation
       npm install express
       npm install express-generator
   Global installation
       npm install express -g
       npm install express-generator -g
   The difference is that -g
   global installation address is C:\Users\Administrator\AppData\Roaming\npm\ node_modules folder.
   It is best to run commands under the npm folder when installing non-globally.
2. Create a project
   To create a node project in idea, you must first install the nodeJs plug-in. The plug-in is not long-winded, just search for it, new project > nodejs and NPM > finish.
   
   ok,
   select bin>www to run and it will start running.
