NativeScript示例應用程序僅需2.36秒即可查看簡單更改

Question

檢查NativeScript。 創建示例android應用程序。沒有添加新文件。 只是改變顏色

<color name="ns_primary">#2196F3</color>  
<color name="ns_primaryDark">#1565C0</color> 

和運行tns run android需要Total time: 2 mins 26.62 secs看到我的變化。因爲livesync不適用於app\App_Resources\Android\values\colors.xml和msg我重建。

我是否運行錯誤的命令只是爲了看到更改？

使用Microsoft Android Emulator

您使用角+ NativeScript任何機會，如果是緩慢的構建是由於的JavaScript文件量角2個附帶。爲了使{N}完全直接訪問本地API，它將解析任何JavaScript文件並在構建時查找這些調用。如果node_modules或app文件夾中有很多js文件，這當然會導致構建速度變慢。

在NativeScript repo上有一個關於此問題的github問題，在那裏有很多關於團隊如何處理這個問題的想法，但它仍然在進行中，而且Angular 2還沒有發佈，因此敬請期待。
