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

event-bus-hooks 是一个效力于react的事件发布订阅工具。

安装

npm i event-bus-hooks

基础使用

需引入:

import Bus,{useEventBus} from 'event-bus-hooks';

//订阅
Bus.$on('订阅方法名称',(args)=>{
  // handle
});

// hooks 订阅
useEventBus('订阅方法名称',订阅回调方法,[依赖项]);

// hooks 发布
Bus.$emit('订阅方法名称',args);

//发布
Bus.$emit('订阅方法名称',args);

//取消订阅
Bus.$off('订阅方法名称');

注意: 因为订阅的方法存在闭包,所以如果想要在订阅方法回调中使用最新的变量(如reacr中 redux的值),编码可以如下

或者使用useEventBus。推荐使用useEventBus。精简代码。

useEffect(() => {
    //订阅
    Bus.$on('订阅方法名称',(args)=>{
      console.log(reduxData);
    });
    return ()=>{
      // 取消订阅,防止重复订阅.
      Bus.$off('订阅方法名称');
    }
  }, [reduxData]);
