一年一度的NBA總決賽，相信球迷用的最多的就是騰訊體育這款APP，剛好上手Vue，當練手就把這個APP仿下來。

?在線預覽：點我！！！在線預覽，手機瀏覽或切換瀏覽器移動調試

?源碼地址：Github??求你的小星星～

前端部分

SPA單頁應用，前后端分離，webpack build to dist

移動設備兼容：使用flexible.js和rem處理兼容問題

路由懶加載：Vue Router 處理路由，結合 Vue 的 異步組件 和 Webpack 的 code splitting feature 實現路由懶加載

axios做ajax請求

使用了 Vuex 管理組件間的狀態(tài)，實現非父子組件之間的通信

使用 Vue-draggable實現移動端拖拽排序

mint-UI完成構建圖片懶加載、下拉刷新、infinite-scroll等組件

大圖片、輪播圖通過 sessionStorage 存儲

后端部分

mock模擬數據

express 做靜態(tài)資源目錄

待更新的功能

處理數據相關性，讓圈子組件和文章組件對應顯示

改用 express 拋接口

用 express + mongodb 保存用戶狀態(tài)

使用了Vue的異步組件和Webpack的code splitting feature實現路由組件的懶加載當打包構建應用時，Javascript包會變得非常大，影響頁面加載。如果我們能把不同路由對應的組件分割成不同的代碼塊，然后當路由被訪問的時候才加載對應組件，這樣就更加高效了。這樣剛進去的時候頁面加載時間明顯減短。

眾所皆知，h5原生的drag事件對移動端是無效的，因此，移動端的拖拽實現，依賴于touchstart、touchend和scroll的坐標計算，實現起來非常麻煩，Vue-draggable可以讓我們輕松實現跟PC端效果一樣的拖拽排序。

?文檔地址：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

安裝依賴

npm install vuedraggable --save

構造拖拽區(qū)域

需要注意：Action 類似于 mutation，不同在于：

Action 提交的是 mutation，而不是直接變更狀態(tài)。

Action 可以包含任意異步操作。

頻道訂閱的狀態(tài)改變對應路由的變化

圈子訂閱的狀態(tài)改變對應訂閱列表的雙向顯示
