Nodejs+robotjs realizes the function of controlling mouse and keyboard

This article will introduce you to NodejsHow to use robotjs to easily control the mouse and keyboard. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to everyone.

I have recently completed the development of a chat system based on vue. In my spare time, I tinkered with the node script. It is quite troublesome to start up the computer every day at work. I have to open the software one by one. Manually connect to wifi; then, I tinkered with a very simple automatic execution script. After executing node file name.js, it will automatically connect to the Internet and open various software;

This example first installs npm i robotjs and npm i opn (opn 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)

has 4 key points:

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

• Introducing robotjs, a library specializing in nodejs desktop automation, direct access to the ROBOT official website

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

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

Of course, if you want to be more awesome, you can write a file that will automatically execute on startup. No need to add node file name.js. Here is a small example of automation to help friends who don’t know much about robotjs. Everyone, 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 ​​
