基于NodeJS的前端部署工具，将前端打包好的目录进行压缩、上传到服务器、备份并且解压到服务器目录

const fs = require('fs');
const path = require('path');
const archiver = require('archiver');
const log = require('../util/log');

module.exports = function compress (destPath, sucCb, failCb) {
  if (!fs.existsSync(destPath)) {
    return log.error(`不存在 ${ destPath } 目录`);
  }

  const filename = path.basename(destPath);
  const output = fs.createWriteStream(`${ filename }.zip`);
  
  // 写入结束
  output.on('close', () => {
    const kb = archive.pointer() / 1024;
    const unit = kb > 100 ? 'MB' : 'KB';
    log.success(`
      生成的大小${ (kb > 100 ? kb / 1024 : kb).toFixed(1) + unit }
      请在当前目录下寻找${ filename }.zip文件
    `);
    sucCb(destPath + '.zip');
  });
  output.on('end', () => {
    log.error('压缩失败');
    failCb && failCb();
  });
  const archive = archiver('zip', { 
    zlib: { level: 9 } 
  });
  archive.on('error', () => {
    log.error('压缩失败');
    failCb && failCb();
  });
  archive.pipe(output);
  archive.directory(destPath, false);
  archive.finalize();
}
