用nodejs写的一个简单项目打包工具_json

XX.define('ns',['tool/cookie'],function(){
});
//或者
XX.define('ns.ns2','tool/cookie,tool/abc',function(){
})
//或者
XX.define('ns',function(){
})

//通用模块
var Util = require('util'),

PATH =require('path');

var packagedObj = {};//是否已经打包过

module.exports = function(filePath, rootPath, opts){

var str = jscombo(filePath,rootPath);
if(opts.unzip){
return str;
}else{
return Uglify(str);
}
};

function jscombo(filePaths, rootPath){

filePath = PATH.join(rootPath,filePath);

//只打包一次
if(packagedObj[filePath]){
return '';
}
packagedObj[filePath] = 1;

//是否存在
if(FS.existsSync(filePath)){
//异步读取内容

//移出BOM头

//返回内容

}else{
//文件不存在错误信息
