nodejs将vue的dist目录文件copy到目标目录

利用nodejs拷贝转移文件

nodejs将vue的dist目录文件copy到目标目录

上篇文章写了《window批处理执行webpack打包》，这篇文章主要写打包好的文件自动转移到git目录下。
其实就是用的nodejs的读写文件API而已，代码不多，见下面：

let fs = require('fs');
let fse = require('fs-extra') // 文件的正删改查模块，比原生方便
let path = require('path');

// 复制文件
var copy=function(src,dst){
  let paths = fs.readdirSync(src); //同步读取当前目录
  paths.forEach(function(path){
      var _src=src+'/'+path;
      var _dst=dst+'/'+path;
      fs.stat(_src,function(err,stats){  //stats  该对象 包含文件属性
          if(err)throw err;
          if(stats.isFile()){ //如果是个文件则拷贝 
              let _dst = dst+'/' + path;
              let  readable=fs.createReadStream(_src);//创建读取流
              let  writable=fs.createWriteStream(_dst);//创建写入流
              readable.pipe(writable);
          }else if(stats.isDirectory()){ //是目录则 递归 
              checkDirectory(_src,_dst,copy);
          }
      });
  });
}
// 检查文件夹是否存在，新建文件夹并copy
var checkDirectory=function(src,dst,callback){
  fs.access(dst, fs.constants.F_OK, (err) => {
      if(err){
          fs.mkdirSync(dst);
          callback(src,dst);
      }else{
          callback(src,dst);
      }
    });
};

// 删除旧文件
var cleanOld = function(dest) {
  let dest_static = path.join(dest, 'static'); 
  let dest_index = path.join(dest, 'index.html'); 
  fs.exists(dest_static,function(exists){
    if(exists) fse.removeSync(dest_static);
  });
  fs.exists(dest_index,function(exists){
    if(exists) fse.removeSync(dest_index);
  });
}

// 文件路径
let url_src_ehome = path.relative(__dirname, 'C:\\WORK\\new-airport\\6 编码\\5 Web\\ejashop\\dist\\'),
    url_dest_ehome = path.relative(__dirname, 'C:\\Users\\kaiya\\Desktop\\公司文件\\gitlang\\langcnew\\demo2\\ehome'),
    url_src_airport = path.relative(__dirname, 'C:\\WORK\\new-airport\\6 编码\\5 Web\\airport\\dist\\'),
    url_dest_airport = path.relative(__dirname, 'C:\\Users\\kaiya\\Desktop\\公司文件\\gitlang\\langcnew\\demo2\\airport'),
    url_src_operation = path.relative(__dirname, 'C:\\WORK\\new-airport\\6 编码\\5 Web\\eHomeOperation\\dist\\'),
    url_dest_operation = path.relative(__dirname, 'C:\\Users\\kaiya\\Desktop\\公司文件\\gitlang\\langcnew\\demo2\\operation'),
    url_src_openShop = path.relative(__dirname, 'C:\\WORK\\new-airport\\6 编码\\5 Web\\kaidian\\dist\\'),
    url_dest_openShop = path.relative(__dirname, 'C:\\Users\\kaiya\\Desktop\\公司文件\\gitlang\\langcnew\\demo2\\openShop');

// copy之前先清空旧文件
cleanOld(url_dest_ehome);
cleanOld(url_dest_airport);
cleanOld(url_dest_operation);
cleanOld(url_dest_openShop);

// 4个项目的copy转移
checkDirectory(url_src_ehome, url_dest_ehome,copy);
checkDirectory(url_src_airport, url_dest_airport,copy);
checkDirectory(url_src_operation, url_dest_operation,copy);
checkDirectory(url_src_openShop, url_dest_openShop,copy);

这里需要注意一点，path.relative(__dirname, ‘C:\WORK\new-airport\6 编码\5 Web\ejashop\dist\‘);利用path模块将两个绝对路径变成相对路径。
