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 🙏

视频回溯 packBack-sdk 使用指南

使用方式

方式1:npm 安装

npm i pageback-sdk
import Pageback from "pageback-sdk";

const pageBack = new Pageback();
Vue.prototype.$pageBack = pageBack;

方式2:CDN

CDN 下载地址为: pageback-sdk, 可选择对应版本使用或下载

    <script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/index.umd.js"></script>

接口说明

initRecord(options)

能通过pageBackSDK.initRecord(options)初始化回溯参数,Promise 接口

参数options:

| 名称 | 类型 | 可选 | 默认值 | 描述 | | -------------- | ------ | ---- | ------ | ------------------------------------ | | initUrl | string | 否 | | 回溯生成全局唯一序列号的接口地址 | | confirmUrl | string | 否 | | 回溯结束视频上报的接口地址 | | saveUrl | string | 否 | | 回溯实时上传视频的接口地址 |

示例:

this.$pageBack.initRecord({
  initUrl: "http://test.com/ltapp/rrv/v/vbtrack/get_snowflake_id",
  confirmUrl: "http://test.com/ltapp/rrv/v/vbtrack/up_trace",
  saveUrl: "http://test.com/ltapp/rrv/v/vbtrack/up_video"
});

注:若需要获取当前实例信息,可在执行 initRecord 之后从实例pageBack中按需获取,实例属性包含以下内容

| 名称 | 描述 | | -------------- | ------------------------------------ | | tractId | 视频回溯序列号 | | index | 视频节点序号 | | firstStartTime | 视频流程开始时间 | | emitData | 当前内存中保存的采集数据 |

示例:

this.$pageBack.initRecord({
  initUrl: "http://test.com/ltapp/rrv/v/vbtrack/get_snowflake_id",
  confirmUrl: "http://test.com/ltapp/rrv/v/vbtrack/up_trace",
  saveUrl: "http://test.com/ltapp/rrv/v/vbtrack/up_video"
}).then(() => {
  console.log('tractId', this.$pageBack.tractId)
});

startRecord(options)

能通过packBack.startRecord(options) 开启回溯,Promise 接口

参数options:

| 名称 | 类型 | 可选 | 默认值 | 描述 | | ----------------- | ------ | ---- | ------------ | ---------------------------------------------------------------------------------------------- | | page_id | string | 是 | '' | 页面id,默认 '' | | page_name | string | 是 | '' | 页面名称,默认 '' | | thresholdSize | number | 是 | 512*1024 | 实时上报字符数量阈值,number类型,默认 512*1024,上限 3 M | | recordConfig | object | 是 | | 录制配置参数,具体见下方 recordConfig 参数参考 |

recordConfig 参数参考

| key | 默认项 | 功能 | | --- | --- | --- | | isPack | false | 是否开启单数据压缩 | | blockClass | 'rr-block' | 字符串或正则表达式,可用于自定义屏蔽元素的类名 | | blockSelector | null | 字符串或正则表达式,可用于自定义屏蔽元素的类名 | | maskTextClass | 'rr-mask' | 字符串或正则表达式,可用于自定义忽略元素 text 内容的类名 | | maskTextSelector | null | null 所有 element.matches(maskTextSelector)为 true 的元素及其子元素的 text 内容将会被屏蔽 | | maskAllInputs | false | 将所有输入内容记录为 * | | recordCanvas | false | 是否记录 canvas 内容, 可用选项:false, true | | assetsUrl | null | 静态资源服务地址。通过该参数可以将项目内图片、css资源路径改写成指定的静态资源服务地址 | | assetsVersion | null | 静态资源服务资源路径。通过该参数可以将项目内图片、css资源路径改写成指定的静态资源服务地址 | | assetsReplace | [] | 参数类型 {origin: string; target: string}[] 。静态资源路径替换。例如:当配置参数如下:[{origin:"http://www.aaa.com",target:"http://www.bbb.com"}],会将录制页面中域名为http://www.aaa.com 的图片替换成 http://www.bbb.com ,最终回放界面以http://www.bbb.com 的资源进行回放 |

更多录制参数参见:rrweb 配置参数

示例:

this.$pageBack.startRecord({
  page_id: "0001",
  page_name: "测试1",
  thresholdSize: 512,
  recordConfig: {
    inlineStylesheet: true,
    recordCanvas: true,
    sampling: {
      canvas: 10,
    },
    // 图像的格式
    dataURLOptions: {
