Node.js基于Webpack Watch实现SFTP自动上传脚本

sftp
 .connect({
 host: '0.0.0.0', // ftp服务器ip地址
 port: '22', // ftp服务器port
 username: 'yourname', // 你的登录用户名
 password: 'yourpass', // 你的密码
 privateKey: fs.readFileSync('/Users/yourname/.ssh/id_rsa'), // 私钥
 passphrase: 'yourpass', // 私钥密码
 })
 .then(() => {
 console.log('ftp文件服务器连接成功');
 })
 .catch(err => {
 console.log(err, 'catch error');
 });

module.exports = sftp;

const path = require('path');
const fs = require('fs');
const yargs = require('yargs');
const webpack = require('webpack');
const webpackConfig = require('./webpack.prod.config');
const sftp = require('./sftp');

const user = yargs.argv.user || '';

console.log(user);

};

const compiler = webpack(webpackConfig);
const watching = compiler.watch(
