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 thennpm 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

Understanding how JavaScript engine works internally is important to developers because it helps write more efficient code and understand performance bottlenecks and optimization strategies. 1) The engine's workflow includes three stages: parsing, compiling and execution; 2) During the execution process, the engine will perform dynamic optimization, such as inline cache and hidden classes; 3) Best practices include avoiding global variables, optimizing loops, using const and lets, and avoiding excessive use of closures.

Python is more suitable for beginners, with a smooth learning curve and concise syntax; JavaScript is suitable for front-end development, with a steep learning curve and flexible syntax. 1. Python syntax is intuitive and suitable for data science and back-end development. 2. JavaScript is flexible and widely used in front-end and server-side programming.

Python and JavaScript have their own advantages and disadvantages in terms of community, libraries and resources. 1) The Python community is friendly and suitable for beginners, but the front-end development resources are not as rich as JavaScript. 2) Python is powerful in data science and machine learning libraries, while JavaScript is better in front-end development libraries and frameworks. 3) Both have rich learning resources, but Python is suitable for starting with official documents, while JavaScript is better with MDNWebDocs. The choice should be based on project needs and personal interests.

The shift from C/C to JavaScript requires adapting to dynamic typing, garbage collection and asynchronous programming. 1) C/C is a statically typed language that requires manual memory management, while JavaScript is dynamically typed and garbage collection is automatically processed. 2) C/C needs to be compiled into machine code, while JavaScript is an interpreted language. 3) JavaScript introduces concepts such as closures, prototype chains and Promise, which enhances flexibility and asynchronous programming capabilities.

Different JavaScript engines have different effects when parsing and executing JavaScript code, because the implementation principles and optimization strategies of each engine differ. 1. Lexical analysis: convert source code into lexical unit. 2. Grammar analysis: Generate an abstract syntax tree. 3. Optimization and compilation: Generate machine code through the JIT compiler. 4. Execute: Run the machine code. V8 engine optimizes through instant compilation and hidden class, SpiderMonkey uses a type inference system, resulting in different performance performance on the same code.

JavaScript's applications in the real world include server-side programming, mobile application development and Internet of Things control: 1. Server-side programming is realized through Node.js, suitable for high concurrent request processing. 2. Mobile application development is carried out through ReactNative and supports cross-platform deployment. 3. Used for IoT device control through Johnny-Five library, suitable for hardware interaction.
