1. Quickly start

installation

Use npm

npm i rrd-web-report-sdk

Use yarn

yarn add rrd-web-report-sdk

Usage

Import as a es6 module

import { WebReport } from 'rrd-web-report-sdk';
const report = new WebReport({
    domain: domain, // the target api to report
    extraData: {
        appId: appId // the unique key to identify where the report from  
    }
});
report.init();

Import as a script tag

<html>
<head>
  <script src="../dist/rrd-web-report-sdk.js"></script>
  <script>
    const report = window.WebReport({
        domain: domain, // the target api to report
        extraData: {
            appId: appId // the unique key to identify where the report from  
        }
    });
    report.init();
  </script>
</head>

2. Configuration

domain

The target api. default value: 'http://localhost/api'

filterUrl

Filter url that we don't want to report. default value: []

openVisitorReport

Open PV/UV report or not. default value: true

openResourceReport

Open resource report or not. default value: true

openAjaxReport

Open ajax/fetch report or not. default value: true

openErrorReport

Open error message report or not. default value: true

openPerformanceReport

Open performance report or not. default value: true

extraData

Extra data including appId. default value: {}

loadReportDelay

Report delay when we have to report when page onload. default value: 5000

3. Data Collection

PV/UV

We use a random string to mark UV and get the UV expired time(today's 23:59:59). And then we store them to localstorage. When the current time exceeds UV expired time, we will refresh them in localstorage to make sure to generate the different UV string in different day. UV string will be added to reportData as markUv.

We will report once when we init rrd-web-report-sdk with a type property equal 10. We call this first report PV/UV report. Because the server can analyse the length of report which has the type equal 10 to get the PV today.

performance

We use window.performance.timing to get the performance information. And we don't have to calculate all timing data. We only need calculate the necessary time that can reflect the performance of the page accurately. The performance information will be added to performance in reportData.

// Time to analyse DNS 
dnst: timing.domainLookupEnd - timing.domainLookupStart || 0,
// Time to setup TCP
tcpt: timing.connectEnd - timing.connectStart || 0,
// Time to read the first byte of the page
wit: timing.responseStart - timing.navigationStart || 0,
// Time to render DOM completely
domt: timing.domContentLoadedEventEnd - timing.navigationStart || 0,
// Time to onload
lodt: timing.loadEventEnd - timing.navigationStart || 0,
// Time to send the first request
radt: timing.fetchStart - timing.navigationStart || 0,
// Time to redirect
rdit: timing.redirectEnd - timing.redirectStart || 0,
// Time to unload
uodt: timing.unloadEventEnd - timing.unloadEventStart || 0,
// Time to load content
reqt: timing.responseEnd - timing.requestStart || 0,
// Time to analyse DOM
andt: timing.domComplete - timing.domInteractive || 0,

resource

We use window.performance.getEntriesByType('resource') method to get the whole resource information. Besides we don't need every property from each data, just reserve decodedBodySize duration method name nextHopProtocol type. The resource information will be added to resourceList in reportData.

error

We want to collect the whole error in the target page such as resource error, dom error and ajax error. So we use addEventListener to watch the error and unrejectederror. We also use a hook to catch the ajax and fetch error.All of the error will be added to errorList in reportData

4. Do report

We need to quickly report the PV/UV information when init rrd-web-report-sdk rather than waiting for the page onload. It can make the PV/UV information more accurate.

{
	"time": 1563864488148,
	"markUv": "C43ipaDf1C1563864488148",
	"type": 10,
	"url": "http://127.0.0.1:9003/mo/about/media/articles/id/5923e08a59e5ea3d2f63a4fb",
	"appId": "wi3kSrS1555926862778"
}

We report the resource, performance and error information when the page unload. Because we can collect the whole information of the target page at that moment. And then we use Navigator.sendBeacon() method to report. Considering compatibility issues, we report those data when the page onload if the browser don't support Navigator.sendBeacon(). By the way, those data sent by Navigator.sendBeacon() will have the default configuration Content-type: text/plain in Request Header.
