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 🙏

简介

bubbleMsg是针对通过<iframe>嵌套的多个窗口间进行通信的vue插件。当前端项目中存在多层<iframe>嵌套,为方便进行层间通信,可以使用此插件。

当需要进行层间通信时,可选单向(向上/向下)或双向进行信息发送,信息会沿此方向冒泡传递,当信息被某层系统捕获并使用,或信息发送至尽头,则停止冒泡传递。

插件的使用有以下模式:

  • 发送-接收模式: 在发送层发送信息,在接收层捕获并使用。

  • 请求-响应模式: 在请求层发送信息并异步等待回复,在响应层捕获信息处理并回复,当请求层收到回复后异步完成。如信息未被响应层捕获,则请求层抛出等待超时的异常。

安装

npm i --save bubble-msg

//在main.js中引用插件

import bubbleMsg from 'bubble-msg'
Vue.use(bubbleMsg)

接口

key:信息的唯一标识符 data:信息内容

$bub.msg(key,data)                      //双向发送信息
$bub.msgUp(key,data)                    //向上发送信息
$bub.msgDown(key,data)                  //双下发送信息
$bub.onMsg(key,(data)=>{})              //捕获消息
$bub.offMsg(key)                        //停止捕获"key"的消息
$bub.offMsg(key,fn)                     //"key"的消息不再使用fn处理
$bub.reqMsg(key,data)                   //请求消息
$bub.reqMsg(key,data,timeout)           //请求消息,设置超时时间,默认10*1000
$bub.onReqMsg(key,(data)=>{return res}) //响应请求消息

使用

发送-接收:

  • 发信息
let data={
  id: 1,
  obj:{a:1,b:2}
}
this.$bub.msg('key', data)      //双向发送
// this.$bub.msgUp('key',data)  //向上发送
// this.$bub.msgDown('key',data)//向下发送
  • 接收信息

推荐在mounted生命周期调用

mounted() {
  this.$bub.onMsg('key', data => {
    console.log('测试监听获得参数:', data)//打印:测试监听获得参数: { id: 1, obj: { a: 1, b: 2 } }
  })
},

请求-响应:

  • 请求获取信息(异步)
//默认timeOut为10*1000
//回调写法
this.$bub.reqMsg('reqMsgKey', { name: 'bub' }).then(res => {
  console.log('测试监听返回数据:', res)
}).catch(err=>{})

//await写法
let res=await this.$bub.reqMsg('reqMsgKey', { name: 'bub' })
console.log('测试监听返回数据:', res)
  • 响应请求,处理并返回信息
this.$bub.onReqMsg('reqMsgKey').then(data => {
  console.log('测试监听请求携带数据:', data)
  return {msg:"hello " + data.name}
})

停止信息接收:

推荐在destroyed/onUnmounted生命周期中调用

this.$bub.offMsg('key')//停止接收"key"的消息

注意事项

1、系统均通过<iframe>嵌套 2、相关嵌套系统均需要使用该插件bubbleMsg
