Optimize Toolset

I’ve always been into building performant and accessible sites, but lately I’ve been taking it extremely seriously. So much so that I’ve been building a tool to help me optimize and monitor the sites that I build to make sure that I’m making an attempt to offer the best experience to those who visit them. If you’re into performant, accessible and SEO friendly sites, you might like it too! You can check it out at Optimize Toolset.

About

Hi, 👋, I’m Ryan Hefner  and I built this site for me, and you! The goal of this site was to provide an easy way for me to check the stats on my npm packages, both for prioritizing issues and updates, and to give me a little kick in the pants to keep up on stuff.

As I was building it, I realized that I was actually using the tool to build the tool, and figured I might as well put this out there and hopefully others will find it to be a fast and useful way to search and browse npm packages as I have.

If you’re interested in other things I’m working on, follow me on Twitter or check out the open source projects I’ve been publishing on GitHub.

I am also working on a Twitter bot for this site to tweet the most popular, newest, random packages from npm. Please follow that account now and it will start sending out packages soon–ish.

Open Software & Tools

This site wouldn’t be possible without the immense generosity and tireless efforts from the people who make contributions to the world and share their work via open source initiatives. Thank you 🙏

event-simple 使用指南 event-simple 是一个简单的实现前端自定义事件监听与触发的库 兼容各大框架

使用 - 基本使用

const eventSimple = require('event-simple')

Monitoring events (监听事件)

eventSimple.on('eventName', function() { 

    let handlerArgs = Array.prototype.slice.call(arguments, 0)

    console.log('arguments:', ...handlerArgs)
})

你可以为同个事件绑定多个方法: 如下
let fn1 = function (arg1, arg2) {
    console.log('the fn1 arg1:', arg1)
    console.log('the fn1 arg2:', arg2)
}
let fn2 = function (arg1, arg2) {
    console.log('the fn2 arg1:', arg1)
    console.log('the fn2 arg2:', arg2)
}

链式调用
eventSimple.on('eventName', fn1).on('eventName', fn2).emit('eventName', 'test1')

emitting events (发送事件)

eventSimple.emit('eventName', 'arg1', 'arg2', ...)

removing events (移除事件)

移除事件绑定的全部方法
eventSimple.off('eventName')

移除绑定事件的指定方法 例:

let fn1 = function (arg1, arg2) {
    console.log('the fn1 arg1:', arg1)
    console.log('the fn1 arg2:', arg2)
}
let fn2 = function (arg1, arg2) {
    console.log('the fn2 arg1:', arg1)
    console.log('the fn2 arg2:', arg2)
}

eventSimple.on('eventName', fn1).on('eventName', fn2)

移除绑定事件的fn1监听
eventSimple.off('eventName', fn1)

支持链式调用

eventSimple.on('eventName', function() { 

    let handlerArgs = Array.prototype.slice.call(arguments, 0)

    console.log('arguments:', ...handlerArgs)

}).emit('eventName', 'arg1', 'arg1')

如果需要在第三方框架上使用,只需要把event-simple挂在全局上即可

如在vue中使用如下:

在main.js中引入并挂在原型上,即可全局调用

import Vue from 'vue' const eventSimple = require('event-simple')

Vue.prototype['$eventSimple'] = eventSimple

new Vue({
   ...
})

这样就可以在项目中的任何地方通过调用

this.$eventSimple.on('eventName', function (a) {
    console.log('arg:',  a)
}).emit('eventName', 233).on('eventName1', function (b) {
    console.log('argb:', b)
}).emit('eventName1', 34234)
