[node. js] NPM init && npm Install

NPM Init:

For create Package.json file which would recode the dependence.

NPM Install:

You can also write like:

This is a shortcut-to-write NPM install.

For example. We want to install Undersocre.js

NPM Install-s Underscore

The '-s ' works is it would write down the dependence into the Package.json we just create:

{  "name":"commonjsbroswerfiy",  "version":"0.0.0",  "Description":"",  "Main":"Index.js",  "Scripts": {    "Test":"echo \ "Error:no test specified\" && exit 1"  },  "author":"",  "License":"MIT",  "Dependencies": {    "Underscore":"^1.7.0"  }}

Dev-dependence:

Install -D Bower

'-d ' is-add dependence into devdependence which only available for the co-work.

{  "name":"commonjsbroswerfiy",  "version":"0.0.0",  "Description":"",  "Main":"Index.js",  "Scripts": {    "Test":"echo \ "Error:no test specified\" && exit 1"  },  "author":"",  "License":"MIT",  "Dependencies": {    "Underscore":"^1.7.0"  },  "devdependencies": {    "Bower":"^1.3.12"  }}

If we have Package.json, the other people download our project and they just need to run:

NPM I

They can install all the dependence.

[node. js] NPM init && npm Install
