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 🙏

Readme

js版本事件总线(类似 android EventBus)

使用说明

1、安装

npm install  universal-event-bus

2、在需要的地方注册事件(需要更新用户数据)

事件的注册跟解除注册需要配对使用,否则会导致内存泄漏; (一般在页面开始的时候注册,页面结束的时候解除。具体根据实际情况而定)

 let eventBus = require('universal-event-bus')
 
 //注册()
 eventBus.register(this, false, 'updateUserInfo', (msg)=>{
    //  msg收到的用户消息,执行相关更新操作
 )
 
 //解除注册
 eventBus.unregister(this);
 

3、发送消息

消息分为普通消息跟粘性消息;普通消息只有在发送消息前注册才能收到,粘性消息,在消息发送之后注册,也能收得到; 要接收粘性消息,需要在注册的时候进行标识(即 第二个参数传 true)

  eventBus.post({name:"AAA",age:20},'updateUserInfo')  
  或者
  eventBus.postSticky({name:"AAA",age:20},'updateUserInfo');//发送粘性消息

4、销毁所有的事件

eventBus.destroy();
