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 Sender

用于支持多个iframe的通信方案

Install

npm install --save message-sender

释义

  • 通信对象
    • T - 顶层消息窗口,唯一
    • A - 应用消息窗口,多个

Usage

T, A都需要进行挂载,T的挂载时肯定比A快的,T、A的挂载请置于程序入口处。

  • 第一步:设置T的挂载
import messageSender from 'message-sender'

// T, T的id默认CORE_APP
messageSender.mount({
  debug: true,
  listen: {
    answer(result) {
      console.log(result.data)

      return 'Yes, I am Core App!'
    },
  }
})

// 和listen相同,用于异步处理,同一个事件只能注册一次
messageSender.on('answer2', () => {
  console.log(result.data)

  return 'Yes, I am Core App! This is answer2'
})
  • 第二步: 设置A的挂载
import messageSender from 'message-sender'

messageSender.mount({
  debug: true,
  id: 'app.a',
  // 依赖注入
  inject: {
    vueStore: { log() { console.log('test...') } },
  },
  listen: {
    answer(result) {
      console.log(result.data)

      return 'Get out here!'
    },
  }
})

messageSender.vueStore.log() // 结果为"test..."

常规通信方式

1、顶层 <-> 应用(消息窗口与顶层窗口相互通信)

T -> A, T给A发送消息,A应答并消息结果返回给T
A -> T, A给T发送消息,T应答并消息结果返回给A

  • T的代码
    T发送数据的时候会检查应用是否被挂载,未被挂载则重试。
import messageSender from 'message-sender'

messageSender.mount({
  debug: true,
  retrySendMaxTimes: 2, // 最大重试次数
  retrySendInterval: 5001, // 每次重试间隔
  listen: {
    orderKFC(result) {
      console.log(result.data)

      return '好的,一份原神异世寻味礼,您稍等~'
    },
  }
})

// 超过重试次数,则会进入catch流程,不再重试
messageSender.send('app.a', 'answer', 'Hello a, I am Core App!').then(result => {
  console.log(result.data)
})
  • A的代码
import messageSender from 'message-sender'

// 这里可以看到A的代码是10秒后延迟挂载的
setTimeout(() => {
  messageSender.mount({
    debug: true,
    id: 'app.a',
    listen: {
      answer(result) {
        console.log(result.data)

        return 'Hi, I am a'
      },
    }
  })

  messageSender.sendTop('orderKFC', '异世相遇,尽享美味').then(result => {
    console.log(result.data) // 结果为“好的,一份原神异世寻味礼,您稍等~”
  })
}, 10000)

2、应用 <-> 应用(消息窗口与消息窗口的通信)

  • A的代码 - app.b
import messageSender from 'message-sender'

messageSender.mount({
  debug: true,
  id: 'app.b'
})

messageSender.send('app.c', 'answer', 'Hello,c!, I am b').then(result => {
  console.log(result.data) // 响应结果为“欢迎收听中文广播电台17301”
})
  • A的代码 - app.c
messageSender.mount({
  debug: true,
  id: 'app.c',
  listen: {
    answer(result) {
      console.log(result.data) // 响应结果为“Hello,c!, I am b”

      return '欢迎收听中文广播电台17301'
    },
  }
})

3、顶层/应用 <-> 多个应用 (广播,支持消息窗口进行广播)

broadcast方法支持SendOption设置

  • T/A的代码
import messageSender from 'message-sender'

// 只能广播给已挂载的窗口
messageSender.broadcast('_(:з」∠)_, 我是广播君!!!!!').then((result) => {
  console.log(result.data) // 结果为 {app.b: {…}, app.c: {…}}, 所有窗口的返回消息,key为id
})

// 广播对应的行为
messageSender.broadcast('_(:з」∠)_, 我是广播君!!!!!', 'answer').then((result) => {
  console.log(result.data) // 结果为 {app.b: {…}, app.c: {…}}, 所有窗口的返回消息,key为id
})
  • A的代码 - app.c
import messageSender from 'message-sender'

messageSender.mount({
  debug: true,
  id: 'app.c',
  listen: {
    // msEventBroadcast是messageSender默认广播接收方法
    msEventBroadcast(result) {
      console.log('common: ', result)

      return '感谢您的广播来电,请问需要咨询什么情感问题?'
    },
  }
})

订阅与发布

通信事件有且只能注册一个,这里通过订阅发布来处理窗口消息发布,以及响应窗口的,该模式是建立在通信广播的逻辑上。

  • A的代码 - app.b
// 订阅app.c的消息
const appCSubscribe = messageSender.subscribe('app.c')

// 订阅行为
appCSubscribe.on('fileChange', result => {
  console.log(result)
})

// 和on方法不同,可以多次订阅相同行为
appCSubscribe.on('fileChange', result => {
  console.log(result)
})
  • A的代码 - app.c
// 推送app.c的消息
messageSender.publish('fileChange', { filePath: '/xxxxx/xxxxx/xxxx/happy.avi' })
