页面停留时间（TP）

页面停留时长同样借助effect函数，通过计算页面变化的时间差从而上报页面停留时长事件，一般当进入第二个页面才会统计第一个页面的TP，进入三个页面计算第二个页面的TP。。。所以我们把逻辑写在getVisitor函数中然后给它改个名

//上报uv&pv&TP
const getVisitorAndTP = (app, prefix) => {
  const globalProperties = reactive(app.config.globalProperties);
  let startTime = new Date().getTime();
  let path = "";
  let lastPath = "";
  effect(() => {
    const endTime = new Date().getTime();
    const TP = endTime - startTime;
    startTime = endTime;
    lastPath = path;
    path = globalProperties.$route.path;
    //间隔为0不上报
    if (!TP) return;
    console.log({
      eventName: `${prefix}_${path}`,
    });
    //页面停留时长小于0.5s不上报
    if (TP < 500) return;
    console.log({
      eventName: `${prefix}_${TP}_${lastPath}`,
    });
  });
};
export default {
  install: (app, options) => {
    app.directive("click", {
      created: (el, bind) => {
        el.addEventListener("click", () => {
          console.log(bind.value);
        });
      },
    });
    //挂载全局用于手动上报
    app.config.globalProperties.$vtrack = (params) => {
      console.log(params)
    }
  }
}

上传TP事件的格式为prefix_TP_path,因此我们切换页面的时候可以看到同时上报的两个事件

获取公共参数

根据用户传来的固定参数baseParams和事件前缀prefix调整我们上报事件形式。假设在main.js用户传来这些数据

import { createApp } from "vue";
import App from "./App.vue";
import router from "./router/index";
import vTracking from "v-tracking";
const app = createApp(App);
app.use(router);
app.use(vTracking, {
  baseParams: {
    uid: 123,
    userAgent: "Chrome",
  },
  prefix: "app",
});
app.mount("#app");

然后修改一下我们的插件(这里将uv/pv还有TP作为单独参数上报，不再使用上面的eventName形式，太懒了，上面的写法不想改了😑)

import { reactive, effect } from "@vue/reactivity";
//上报uv&pv&TP
const getVisitorAndTP = (app, prefix, baseParams) => {
  const globalProperties = reactive(app.config.globalProperties);
  let startTime = new Date().getTime();
  let path = "";
  let lastPath = "";
  effect(() => {
    const endTime = new Date().getTime();
    const TP = endTime - startTime;
    startTime = endTime;
    lastPath = path;
    path = globalProperties.$route.path;
    //间隔为0不上报
    if (!TP) return;
    console.log({
      ...baseParams,
      UPVEventName: `${prefix}_${path}`,
    });
    //页面停留时长小于0.5s不上报
    if (TP < 500) return;
    console.log({
      ...baseParams,
      TP: {
        path: lastPath,
        time: TP,
      },
    });
  });
};
export default {
  install: (app, options) => {
    const { prefix, baseParams } = options;
    getVisitorAndTP(app, prefix || "track", baseParams || {});
    app.directive("click", {
      created: (el, bind) => {
        el.addEventListener("click", () => {
          console.log({ ...bind.value, ...(baseParams || {}) });
        });
      },
    });
    //挂载全局用于手动上报
    app.config.globalProperties.$vtrack = (params) => {
      console.log(params);
    };
  },
};

此时这控制台打印出事件类型上报格式为

引入axios

最后简单写一个axios的请求函数，这里不考虑请求失败的情况，此时需要用户传入一个baseUrl

import { reactive, effect } from "@vue/reactivity";
import axios from "axios";
axios.defaults.headers["Content-Type"] = "application/json";
const request = (baseUrl, params) => {
  axios({
    url: baseUrl,
    method: "post",
    data: params,
  });
};
//上报uv&pv&TP
const getVisitorAndTP = (app, prefix, baseParams, baseUrl) => {
  const globalProperties = reactive(app.config.globalProperties);
  let startTime = new Date().getTime();
  let path = "";
  let lastPath = "";
  effect(() => {
    const endTime = new Date().getTime();
    const TP = endTime - startTime;
    startTime = endTime;
    lastPath = path;
    path = globalProperties.$route.path;
    //间隔为0不上报
    if (!TP) return;
    request(baseUrl, {
      ...baseParams,
      UPVEventName: `${prefix}_${path}`,
    });
    //页面停留时长小于0.5s不上报
    if (TP < 500) return;
    request(baseUrl, {
      ...baseParams,
      TP: {
        path: lastPath,
        time: TP,
      },
    });
  });
};
export default {
  install: (app, options) => {
    const { prefix, baseParams,baseUrl } = options;
     getVisitorAndTP(app, prefix || "track", baseParams || {}, baseUrl);
    getVisitorAndTP(app, prefix || "track", baseParams || {});
    app.directive("click", {
      created: (el, bind) => {
        el.addEventListener("click", () => {
          console.log({ ...bind.value, ...(baseParams || {}) });
        });
      },
    });
    //挂载全局用于手动上报
    app.config.globalProperties.$vtrack = (params) => {
      console.log(params);
    };
  },
};

此时便可以看到事件的请求了

打包发布

最后使用vite进行打包发布，全局安装vite

pnpm add vite -w -D

然后在v-tracking下新建vite.config.js,配置库模式打包cjs和es格式

import { defineConfig } from "vite";
import { resolve } from "path";
export default defineConfig({
  build: {
    target: "modules",
    //压缩
    minify: true,
    rollupOptions: {
      input: ["index.js"],
      //忽略文件
      external: ["@vue/reactivity", "axios"],
      output: [
        {
          format: "es",
          //不用打包成.es.js,这里我们想把它打包成.js
          entryFileNames: "[name].js",
          //配置打包根目录
          dir: resolve(__dirname, "./dist/es"),
        },
        {
          format: "cjs",
          //不用打包成.mjs
          entryFileNames: "[name].js",
          //配置打包根目录
          dir: resolve(__dirname, "./dist/lib"),
        },
      ],
    },
    lib: {
      entry: "./index.js",
      name: "vtrack",
    },
  },
});

然后将v-tracking/package.json入口文件指向打包后路径，其中module代表如果项目支持es格式的话就会使用dist/es/index.js这个路径

{
  "name": "v-tracking",
  "version": "1.0.0",
  "main": "dist/lib/index.js",
  "module": "dist/es/index.js",
  "description": "",
  "keywords": [],
  "files": [
    "dist"
  ],
  "dependencies": {
    "@vue/reactivity": "^3.2.37",
    "axios": "^0.27.2"
  },
  "author": "",
  "license": "MIT"
}

最后在v-tracking目录下执行pnpm publish进行发布（这里需要注册npm账户等等）

使用说明

安装

npm install v-tracking -S

在 main.js 中引入插件

import { createApp } from "vue";
import App from "./App.vue";
import router from "./router/index";
import vTracking from "v-tracking";
const app = createApp(App);
app.use(router);
app.use(vTracking, Options);
app.mount("#app");

注意

因为涉及到路由检测，所以必须配合vue-router使用

Options

baseParams （string）

公共参数，每次上报都会携带的参数，比如用户的登录信息 uid 等

baseUrl （string）

上报的后台请求地址，后端接口需按照前端请求参数设计

prefix （string）

PV&UV&TP 事件前缀，一般用于区分不同项目等（建议和普通事件前缀一致）

isVisTP （Boolean）

是否统计页面 UV&PV&PT

Options 示例

app.use(vTracking, {
  baseParams: {
    uid: 123
  },
  baseUrl: "http://example/event",
  prefix: "app",
  isVisTP: false,
});

点击指令上报

<template>
    <div>page1</div>
    <div v-click="{ eventName: 'test1' }">click</div>
</template>

后台接收数据格式为

{ uid: 123 , eventName: "test1" }

手动上报

<template>
    <div>page1</div>
    <div @click="track">click</div>
</template>
<script setup>
import { getCurrentInstance } from 'vue';
const { proxy } = getCurrentInstance()
//手动上报事件
const track = ()=>{
  proxy.$vtrack({ eventName: 'test1'  })
}
</script>

后台接收数据格式为

{ uid: 123, eventName: "test1" }

UV&PV

isVisTP为 true 时候插件会自动上报每个页面进入时的数据，其中后台接收数据格式为

{ uid: 123, UPVEventName: `${prefix}_${path}` }

其中path为页面路由路径，如/page1

页面停留时长（TP）

isVisTP为 true 时候插件会自动上报每个页面用户停留时长，其中后台接收数据格式为

{
  uid: 123,
  TP: { path: "/page2", time: 1269446 },
}

time 则表示时长（ms）
