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 🙏

monitor-fe

电商前端监控器

介绍

前端项目运行在客户端(比如小程序、公众号、手机浏览器、pc电脑上等),运行情况我们是不可知的,当出现错误和问题时我们无法第一时间知晓,等客户反馈以后再处理会有很大的延迟,可能对客户造成巨大的经济损失。为了解决这个问题,我们开发了此项目:前端监控器。可以实时搜集错误信息生成日志上报到企业微信群中,方便及时修复问题。

特性

  • 快捷引入,使用npm管理包
  • 内部自动捕获浏览器抓取的报错、promise抛出的报错、vue语法报错(需要在初始化配置表设置vue为true)
  • 可自定义各接入项目的名称
  • 支持自定义延迟合并上报间隔时间(会自动对高频错误进行去重合并,并延时上报)
  • 支持白名单过滤
  • 白名单支持正则匹配
  • 支持小程序接入
  • 支持自定义任意数据,会自动合并上报到更多信息中
  • 支持自定义上报请求方法,比如在小程序中使用wx.request上报
  • 支持自定义设备信息,可以自己实现浏览器信息收集

安装

使用npm:

$ npm install monitor-fe -S

引入

import webMonitor from 'monitor-fe'

初始化

window.webMonitor = new WebMonitor({
  systemName: 'your-system-name',  //【必填】接入方系统名称,一般为git名称
  reportUrl: (process.env.NODE_ENV === 'prod' ? 'https://xxx.xxx.cn' : 'https://test-xxx.xxx.cn') + '/web-monitor/web/monitor', // 【必填】上报接口地址
  userId: 362386428743, //【非必填】用户id
  shopId: 2, //【非必填】店铺id
  delayTime: 10000, //【非必填】延迟合并去重上报间隔
  vue: false, //【必填】是否需要引入vue
  mini: false, //【非必填】是否是小程序接入:默认是在小程序环境里,为了兼容小程序老代码
  wx: wx,  //【非必填】微信对象,只有小程序接入才需要配置此项且配置为 wx 即可
  ajax: (reportData) => { //【非必填】外部传入的ajax方法,可以在接入方覆写上报请求
    wx.request({
      url: '...', 
      method: 'post', 
      data: reportData
    })
  }, 
  getUserAgent: () => { //【非必填】外部传入的设备数据方法,可在接入方覆写获取设备数据或浏览器信息方法
    return '这是自己获取的设备信息'
  } 
})

初始化时同步设置自定义参数

window.webMonitor = new WebMonitor({
  ... 上述各种参数,
  key1: value1,
  key2: value2,
  key3: value3,
  zhangsan: 111,
  lisi: [1,2,3,4,5],
  wangwu: {
    aaa:'uuuu',
    bbb:'ggggg'
  }
})

任意时刻异步设置自定义参数

window.webMonitor && window.webMonitor.setOption({
  key1: value1,
  key2: value2,
  key3: value3,
  zhangsan: 111,
  lisi: [1,2,3,4,5],
  wangwu: {
    aaa:'uuuu',
    bbb:'ggggg'
  }
})

发送自定义错误事件

错误类型为httpError时

使用axios:

window.webMonitor && window.webMonitor.emit({
  type: 'httpError',
  error: response //使用axios响应拦截器里的返回对象即可
})

自己实现axios中的数据结构

window.webMonitor && window.webMonitor.emit({
  type: 'httpError',
  error: {
    config: {
      method: 'get',
      data: {
        id: '875983275892739'
      },
      headers: {
        'Content-type': 'application/json'
      }
    },
    request: {
      responseURL: 'https://xxx.xxx.cn/api/demo'
    }
  }
})

错误类型tryCatchError时

在try catch语句中调用:

window.webMonitor && window.webMonitor.emit({
  type: 'tryCatchError',
  error: error
})

错误类型为其他时

window.webMonitor && window.webMonitor.emit({
  type: 'yuanyuanError',
  error: 'this is a error message!'
})

或者

window.webMonitor && window.webMonitor.emit({
  type: 'yuanyuanError',
  error: new Error('this is a error message!')
})

维护白名单

在自己部署的静态资源库仓库 http://xxx.xxx.cn/common-static 中,修改monitor-white-list.json文件

白名单正则表达式写法


示例:

"239": "<TimePicker> at packages/date-picker/src/panel/time.vue",
"240": "$$【^, {}$】【g】",
"241": "$$【^https://xxx.xxx.cn/cp/static/js/app.】",
"242": "$$【^Unhandled promise rejection, {}$】, 【g】"

说明: $$为正则语句标识符,【】括号也是边界符, 第一个参数为表达式, 第二个参数为匹配范围。
