node js 打包文件

node js 、 依赖包JSZIP

打包 压缩

fileCompression: (folderPath) ->
    zip = new JSZip()
    zipPath = pathM.join folderPath,'..',pathM.basename(folderPath)+'.zip'
    flag = "root"

    compressionZip= (node,filePath,isroot) =>
      # windows 和 linux 文件路径兼容处理
      stats = fs.statSync(filePath)
      # 1、将 windows 文件路径的 \ 转为 linux 文件路径的 /
      str1=node.replace(/\\/g,"/")
      # 2、切割路径
      strs=str1.split("/")
      tmp = zip
      if strs[0] is "."
        isroot = true
      # 3、以 tmp 保存当前 最外层文件夹
      getLast = (filePath) =>
        tmp = tmp.folder(filePath)
      if strs isnt null and strs.length isnt 0
        getLast fileItem for fileItem in strs
      # 4、保存文件夹或者文件
      if stats.isFile()
        fileName = pathM.basename(filePath)
        if isroot
          zip.file(fileName,fs.readFileSync(filePath))
        else
          tmp.file(fileName,fs.readFileSync(filePath))
      else
        if flag is "root"

          compressionZip folderZipPath,pathM.join(filePath,filePathItem),false for  filePathItem in fileList
    compressionZip ".",folderPath,true
    # 5、保存 zip
    content = zip.generate({type:"nodebuffer",compression:"DEFLATE"})
    fs.writeFileSync(zipPath,content)

    fs.readFile(zipPath,cb)
