Nodejs uses robotjs to easily control the mouse and keyboard

I have just completed a project based on vue During the development of the chat system, I tinkered with the node script in my spare time. It was very troublesome to start up the computer every day at work. I had to open the software one by one and connect to the wifi manually. So, I tinkered with a very simple automatic execution script and executed node After the file name is .js, various software will be automatically opened online;

In this example, we first install npm i robotjs and npm i opn (opn It has nothing to do with controlling the mouse and keyboard)

The simple code is as follows (after npm has installed the dependencies, the following code can be copied and executed directly):

const opn = require('opn');     //执行语句
var robot = require("robotjs");   //控制鼠标键盘等操作
 
var screenSize = robot.getScreenSize();
robot.moveMouseSmooth(screenSize.width-140, screenSize.height-20);	//移动鼠标
robot.setMouseDelay(1000)	
robot.mouseClick();	 //鼠标点击
robot.moveMouseSmooth(screenSize.width-140, screenSize.height-560);
robot.setMouseDelay(2000)
robot.mouseClick()
robot.moveMouseSmooth(screenSize.width-140, screenSize.height-490);
robot.setMouseDelay(1000)
robot.mouseClick()

opn('C:/Users/seagm/Desktop/小白入门手册.txt');	//自动打开程序（文件地址自己修改即可）
opn('C:/Users/seagm/Desktop/GitHub Desktop')
opn('C:/Users/seagm/Desktop/Visual Studio Code')
opn('', {app: 'chrome'});
setTimeout(()=>{opn('C:/Program Files (x86)/Tencent/WeChat/WeChat.exe')},2000)

There are 4 key points:

• Introduce opn, you can also directly use the child_process that comes with node; used to execute statements for operating files

• Introduce robotjs, a library specializing in nodejs desktop automation ROBOT official website Directly

• Pay attention to the direction of the slash in the URL parameter of the operation file

• If an error occurs when installing robotjs, execute as an administratornpm install --global --production windows-build-tools, and then npm i robotjs

Of course, if you want to be more awesome, you can write a file to automatically execute it on startup without changing the node file name. .js, here is a little introduction, a small automation chestnut to help friends who don’t know much about robotjs. The specific API of robotjs can be directly accessed from the official website above. . .
Since then, I have saved another 30 seconds every day, haha ​​
