Cordova CLI源码分析（二）——package.json

每个包需要在其顶层目录下包含一个package.json文件，该文件不仅是包的说明，也影响npm安装包时的配置选项

更多参数详见参考文档https://npmjs.org/doc/json.html

{
"name": "cordova",
"version": "3.0.4",
"preferGlobal": "true",//如果安装包是作为命令行应用程序，应该全局模式安装，如果用户使用本地模式安装，则警告提醒
"description": "Cordova command line interface tool",
"main": "cordova",
//表示Node.js在调用某个模块的时候，将寻找main指向的路径作为模块的接口，在这里Node将寻找同目录下的cordova文件，并尝试从它那加载模块；
//如果没有cordova，Node还是会尝试寻找cordova.js或者cordova.node作为包的接口。
//相当于这是初始化函数，返回此文件中export的对象内容
"engines":{
"node":">=0.9.9"
//指定使用node的版本
},
"engineStrict":true,
//如果确定模块只能能在engines 参数指定的版本正常工作，则设置此参数
"bin": {
"cordova": "./bin/cordova"
//用户在命令行输入时，解析参数执行此文件

cordova文件

#!/usr/bin/env node
var CLI = require('../src/cli');
new CLI(process.argv);

},

"test": "jasmine-node --color spec"
//存储一些默认运行命令脚本信息
//cordova test 执行 jasmine-node --color spec
