上一节：什么是微信小程序

零售商城模板

一、业务介绍

零售行业模版小程序是个经典的单店版电商小程序，涵盖了电商的黄金链路流程，从商品->购物车->结算->订单等。小程序总共包含 28 个完整的页面，涵盖首页，商品详情页，个人中心，售后流程等基础页面。采用 mock 数据进行展示，提供了完整的零售商品展示、交易与售后流程。页面详情：

主要页面截图如下：

example-homeexample-sortexample-cartexample-user-centerexample-goods-detailexample-payexample-orderexample-order-detail

二、项目构成

零售行业模版小程序采用基础的 JavaScript + WXSS + ESLint 进行构建，降低了使用门槛。

项目目录结构如下：

在这里插入图片描述

|-- mall-starter
    |-- README.md
    |-- app.js    //JavaScrip文件
    |-- app.json   // 项目配置文件，负责窗口颜色等等
    |-- app.wxss   //类似CSS文件
    |-- components  //  公共组件库
    |-- config  //  基础配置
    |-- custom-tab-bar  //  自定义 tabbar
    |-- model //  mock 数据
    |-- pages
    |   |-- cart  //  购物车相关页面
    |   |-- coupon  //  优惠券相关页面
    |   |-- goods //  商品相关页面
    |   |-- home  //  首页
    |   |-- order //  订单售后相关页面
    |   |-- promotion-detail  //  营销活动页面
    |   |-- usercenter  //  个人中心及收货地址相关页面
    |-- services  //  请求接口
    |-- style //  公共样式与iconfont
    |-- utils //  工具库

三、 数据模拟

零售小程序采用真实的接口数据，模拟后端返回逻辑，在小程序展示完整的购物场景与购物体验逻辑。

四、项目部分源码

4.1、页面路由及tabBar

{
    
  "pages": [
    "pages/home/home",
    "pages/usercenter/index",
    "pages/usercenter/person-info/index",

  "permission": {
    
    "scope.userLocation": {
    
      "desc": "你的位置信息将用于小程序位置接口的效果展示"
    }
  }
}

4.2、home 首页

    } catch (err) {
