qx-tracker v1.2.6

Tracker

这是一个前端监控和埋点SDK，你可以简单地使用它，为你的web应用收集数据信息

使用方法：

import Tracker from 'qx-tracker';

const tracker = new Tracker({
  requestUrl: 'http://127.0.0.1:9000/tracker',
});

配置

你还需要手动启用需要的功能

考虑到需求不同，防止数据混乱，所有监控功能都默认关闭，要按需启用

/**
 * @uuid 唯一表示用户ID，默认通过canvas指纹生成8位uuid
 * @requestUrl 数据上报API
 * @historyTracker history模式
 * @hashTracker hash模式
 * @errorTracker error事件上报(js、promise等)
 * @domTracker 上报dom事件，需要给被监听元素加上target-key标识
 * @domEventsList 需要监听的dom事件，target-events属性给元素单独指定
 * @performanceTracker 性能监控，页面加载，资源加载等
 * @navigatorTracker 浏览器和设备信息上报
 * @extra 需要携带的额外数据
 * @sdkVersion sdk版本
 * @log 控制台输出信息，
 * @realTime 是否实时上报
 * @maxSize 报告数据最大缓存量，超过该值则会自动上报

interface DefaultOptions {

  }
}

对于dom事件的监听上报，有两个属性细化控制： 1. target-key 标识key，启用对该元素的监听 2. target-events 该元素需要监听的dom事件，为@domEventsList的子集

<button class="a b c" id="d" target-key="btn" target-events="['click']">dom事件上报测试</button>
<div target-key="div" target-events="['mouseover', 'mouseout']" style="width:100px;height:100px;background-color:blue;"></div>

数据

上报数据的获取，一个简单的express服务：

const express = require('express');
const app = express();

app.post('/tracker', express.text(), function (req, res) {
  console.log(JSON.parse(req.body));
  res.send('ok');
});

app.listen(9000, () => {
  console.log('listening on')
})
