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

Node.js excels at efficient I/O, largely thanks to streams. Streams process data incrementally, avoiding memory overload—ideal for large files, network tasks, and real-time applications. Combining streams with TypeScript's type safety creates a powe

The differences in performance and efficiency between Python and JavaScript are mainly reflected in: 1) As an interpreted language, Python runs slowly but has high development efficiency and is suitable for rapid prototype development; 2) JavaScript is limited to single thread in the browser, but multi-threading and asynchronous I/O can be used to improve performance in Node.js, and both have advantages in actual projects.

JavaScript originated in 1995 and was created by Brandon Ike, and realized the language into C. 1.C language provides high performance and system-level programming capabilities for JavaScript. 2. JavaScript's memory management and performance optimization rely on C language. 3. The cross-platform feature of C language helps JavaScript run efficiently on different operating systems.

JavaScript runs in browsers and Node.js environments and relies on the JavaScript engine to parse and execute code. 1) Generate abstract syntax tree (AST) in the parsing stage; 2) convert AST into bytecode or machine code in the compilation stage; 3) execute the compiled code in the execution stage.

The future trends of Python and JavaScript include: 1. Python will consolidate its position in the fields of scientific computing and AI, 2. JavaScript will promote the development of web technology, 3. Cross-platform development will become a hot topic, and 4. Performance optimization will be the focus. Both will continue to expand application scenarios in their respective fields and make more breakthroughs in performance.

Both Python and JavaScript's choices in development environments are important. 1) Python's development environment includes PyCharm, JupyterNotebook and Anaconda, which are suitable for data science and rapid prototyping. 2) The development environment of JavaScript includes Node.js, VSCode and Webpack, which are suitable for front-end and back-end development. Choosing the right tools according to project needs can improve development efficiency and project success rate.

Yes, the engine core of JavaScript is written in C. 1) The C language provides efficient performance and underlying control, which is suitable for the development of JavaScript engine. 2) Taking the V8 engine as an example, its core is written in C, combining the efficiency and object-oriented characteristics of C. 3) The working principle of the JavaScript engine includes parsing, compiling and execution, and the C language plays a key role in these processes.

JavaScript is at the heart of modern websites because it enhances the interactivity and dynamicity of web pages. 1) It allows to change content without refreshing the page, 2) manipulate web pages through DOMAPI, 3) support complex interactive effects such as animation and drag-and-drop, 4) optimize performance and best practices to improve user experience.
