利用nodejs监控文件变化并使用sftp上传到服务器

npm install ssh2-sftp-client
npm install gaze

gaze(['你的文件路径/*.*','还可以使用数组的方式监听多个文件夹/app.js'], function(err, watcher) {
 let watched = this.watched();
 //监听文件的变化
 this.on('changed', (filepath) => {
 //romotePath是我文件的远程位置
 let romotePath = '/root' + filepath.substr(15);
 //put为上传文件的函数，下面会讲 
 put(filepath,romotePath);
 console.log(filepath + ' was changed');
 });
}); 

function put(localPath,romotePath){
 let sftp = new Client();
 sftp.connect({
 host: '你的服务器地址',
 port: '端口，没改过的话是22',
 username: '连接的用户名',
 password: '密码'
 }).then(() => {
 return sftp.put(localPath,romotePath);
 }).then(() =>{
 console.log("上传完成");
 }).catch((err) => {
 console.log(err, 'catch error');
 });
}

let Client = require('ssh2-sftp-client');
let gaze = require('gaze');
