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 pool

Readme

eventpool

事件总线处理器

basic eventpool


import { EventPool } from 'ray-eventpool';

// 监听事件
EventPool.bind('myEvent5', function(event, args, fn) {
  alert('Publish Message 4th Times with args : ' + args);
  fn(args);
});

// 触发事件
function pubshMsg(){
  EventPool.trigger("myEvent5", [ "hello", function(args){
    alert(args);
  }]);
}

basic EventPubSub

  • subscribe 同 bind 监听事件
  • unsubscribe 同 unbind 取消监听
  • one 绑定一次事件
  • publish 同 trigger 触发事件
  • publishHandler 同 triggerHandler 触发事件名称

import { EventPubSub } from 'ray-eventpool';

// 监听事件
EventPubSub.bind('myEvent5', function(event, args, fn) {
  alert('Publish Message 4th Times with args : ' + args);
  fn(args);
});

// 触发事件
function pubshMsg(){
  EventPubSub.trigger("myEvent5", [ "hello", function(args){
    alert(args);
  }]);
}

PubSub

import { PubSub } from 'ray-eventpool';

// 监听
PubSub.subscribe('HELLO', function(topic, data){
  // data
  console.log(data);
});

PubSub.publish('HELLO', '你好!')

// name space
PubSub.publish('HELLO.ray', 'ray 你好!');
PubSub.publish('HELLO.ilex', 'ilex 你好!');

PubSub.subscribe('HELLO', function(topic, data){
  // ray 你好!
  // ilex 你好!
  console.log(data);//
});

EventEjector

import { EventEjector } from 'ray-eventpool';

const ee = new EventEjector();
ee.on('message', function (text) {
  console.log(text)
});
ee.emit('message', 'hello world');

也可以直接使用 nodejs 内置的 events 模块、eventemitter or event-emitter 模块

IHub

通过 new IHub() 创建一个 hub 实例,其中:

hub 提供 hub.event 和 hub.events。

hub.events 是将参数规范话处理,比如 handle的唯一性处理, args 的统一化处理。

建议只使用 hub.events 进行事件分发

import { IHub } from 'ray-eventpool';

// or
import { IHub } from 'ray-eventpool/lib/eventHub';

const hub = new IHub();



hub.events.on('message', function (text) {
  console.log(text)
});

hub.events.emit('message', 'hello world');

也可以直接使用 nodejs 内置的 events 模块、eventemitter or event-emitter 模块
