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 🙏

参数详解

| 参数 | 描述 | | -------- | -----: | | on | 事件注册 | | emit | 事件触发 |

安装

// 使用 npm
npm i create-event-bus
const CreateEventBus = require('create-event-bus'); // 引入方式01
import CreateEventBus from 'create-event-bus'; // 引入方式02

// 使用 cdn (版本可选 @xx.xx.xx)
<script src="https://cdn.jsdelivr.net/npm/create-event-bus@latest/create-event-bus.min.js"></script>

第一步 - 实例化

const bus = new CreateEventBus() // 实例化bus

第二步 - 注册

// 注册永久事件
var demo01 = bus.on('test01', function (res) {
  console.log(res)
})

// 注册永久事件
var demo02 = bus.on('test01', function (res) {
  console.log(res)
})

// 注册一次性事件
var demo03 = bus.once('test01', function (res) {
  console.log(res)
})

// 注册永久唯一事件, 将会覆盖名为 test01 的函数
var demo04 = bus.one('test01', function (res) {
  console.log(res)
})

// 注册一次性唯一事件, 将会覆盖名为 test01 的函数
var demo05 = bus.oneonce('test01', function (res) {
  console.log(res)
})

第三步 - 事件触发

bus.emit('test01', {
  msg: '这是附带的数据',
  data: [1, 2, 3, 4]
})

清空bus实例(页面销毁前或者其他有需要得场景使用)

bus.clear(demo01)
bus.clear(demo02)
bus.clear(demo03)
bus.clear(demo04)
bus.clear(demo05)
