Vue2.0全家桶仿腾讯体育APP（Web版）

摘要：全家桶仿腾讯体育一年一度的总决赛，相信球迷用的最多的就是腾讯体育这款，刚好上手，当练手就把这个仿下来。这样刚进去的时候页面加载时间明显减短。可以包含任意异步操作。

一年一度的NBA总决赛，相信球迷用的最多的就是腾讯体育这款APP，刚好上手Vue，当练手就把这个APP仿下来。

?源码地址：Github✨✨求你的小星星～

前端部分

SPA单页应用，前后端分离，webpack build to dist

移动设备兼容：使用flexible.js和rem处理兼容问题

路由懒加载：Vue Router 处理路由，结合 Vue 的 异步组件 和 Webpack 的 code splitting feature 实现路由懒加载

axios做ajax请求

使用了 Vuex 管理组件间的状态，实现非父子组件之间的通信

使用 Vue-draggable实现移动端拖拽排序

mint-UI完成构建图片懒加载、下拉刷新、infinite-scroll等组件

大图片、轮播图通过 sessionStorage 存储

后端部分

mock模拟数据

express 做静态资源目录

待更新的功能

处理数据相关性，让圈子组件和文章组件对应显示

改用 express 抛接口

用 express + mongodb 保存用户状态

使用了Vue的异步组件和Webpack的code splitting feature实现路由组件的懒加载当打包构建应用时，Javascript包会变得非常大，影响页面加载。如果我们能把不同路由对应的组件分割成不同的代码块，然后当路由被访问的时候才加载对应组件，这样就更加高效了。这样刚进去的时候页面加载时间明显减短。

众所皆知，h5原生的drag事件对移动端是无效的，因此，移动端的拖拽实现，依赖于touchstart、touchend和scroll的坐标计算，实现起来非常麻烦，Vue-draggable可以让我们轻松实现跟PC端效果一样的拖拽排序。

?文档地址：https://github.com/SortableJS...
特性Full support of Sortable.js features:

Supports touch devices
Supports drag handles and selectable text
Smart auto-scrolling
Support drag and drop between different lists
No jQuery dependency
Keeps in sync HTML and view model list
Compatible with Vue.js 2.0 transition-group
Cancellation support
Events reporting any changes when full control is needed

安装依赖

npm install vuedraggable --save

构造拖拽区域

需要注意：Action 类似于 mutation，不同在于：

Action 提交的是 mutation，而不是直接变更状态。

Action 可以包含任意异步操作。

频道订阅的状态改变对应路由的变化

圈子订阅的状态改变对应订阅列表的双向显示
