Node.js publish-subscribe model example explanation
The editor below will bring you an example of the node.js publish-subscribe model. The editor thinks it’s pretty good, and now I want to give it to you and give it as a reference. Let’s follow the editor and take a look.
The examples are as follows:
//导入内置模块
let EventEmitter = require('events');
let util=require('util');
//Man继承EventEmitter
util.inherits(Man,EventEmitter);
//创建一个函数
function Man(){}
//实例化函数
let man=new Man();
function findGirl() {
console.log('找新的女朋友')
}
function saveMoney() {
console.log('省钱')
}
man.on('失恋',findGirl)//失恋 ，绑定一个函数方法
man.on('失恋',saveMoney)//失恋 ，绑定一个函数方法
man.removeListener('失恋',findGirl); //移除省钱
man.emit('失恋');The above is the detailed content of Node.js publish-subscribe model example explanation. For more information, please follow other related articles on the PHP Chinese website!

Comparison of Golang and Node.js in backend development
Jun 03, 2024 pm 02:31 PM
Go and Node.js have differences in typing (strong/weak), concurrency (goroutine/event loop), and garbage collection (automatic/manual). Go has high throughput and low latency, and is suitable for high-load backends; Node.js is good at asynchronous I/O and is suitable for high concurrency and short requests. Practical cases of the two include Kubernetes (Go), database connection (Node.js), and web applications (Go/Node.js). The final choice depends on application needs, team skills, and personal preference.
