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 🙏

message-tool插件使用说明

本插件是mq-wz得增强搬,mq-wz后续不在维护,使用mq-wz项目可以切换至message-tool

import Mq from 'message-tool';

// 创建实例
const event = new Mq(
    type,  // 'memory' | 'localStorage' | 'sessionStorage' 默认memory, 可选
    uid // 唯一标识符, 可选
)

event.setType('localStorage') // 设置type, 会清空之前所有消息

event.getEvents() // 获取所有事件

event.getDataStore() // 获取所有消息数据



// 发布消息
event.emit(topic, eventId, data, {
    enable: true 
    useCount: 1 // 消息使用次数默认不限次数
    expireTime: Date.now() + 1000 * 5 // 消息过期时间默认不过期
})

const options = {
    eventId: '123',
    fn() {},
    execCount: 1
}

event.off(topic, options?) // 删除消息

event.offAll() // 删除所有消息

event.removeStore(topic?) // 删除消息数据

Mq.clearStorage() // 删除所有消息数据

// 设置全局消息域,值为 'sameorigin' | 'crossorigin', sameorigin即同源,crossorigin即跨域
为sameorigin时,只能接收同源消息,且可以跨浏览器tab/iframe之间发送消息
为crossorigin时,可以接收同源和跨域消息,且可以跨iframe之间发送消息,不可跨跨浏览器tab之间发送消息
当作用域设置成功后,会自动触发全局消息topic为message-tool-sameorigin-init/message-tool-crossorigin-init的消息,可以监听该消息进行业务处理
Mq.setScope('sameorigin') 



// 监听消息
event.on(topic, eventId, fn, execCount) // execCount为监听次数

// 跨浏览器tab/iframe之间发送消息 Mq.publish(topic, eventId, data = null, options?)

可选配置 options = { enable: boolean expireTime: number }

注: 通过setScope设置完消息作用域后才可以接收publish发送的消息
