NativeScript 示例应用程序需要 2.36 秒才能看到简单的更改

Question

正在检查 NativeScript。仅创建示例 android 应用程序。没有添加新文件。只是改变颜色

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

和运行 tns run android 需要 Total time: 2 mins 26.62 secs 才能看到我的更改。因为 livesync 不能为 app\App_Resources\Android\values\colors.xml 工作，请告诉我重建。

我运行错误的命令只是为了查看更改吗？

使用Microsoft Android Emulator

Answer 1

您是否有机会使用 Angular + NativeScript，如果是这样，构建缓慢是由于 JavaScript 文件的数量 Angular 2 附带。为了让 {N} 提供对本机 API 的完全直接访问，它会解析任何 JavaScript 文件并在构建期间查找此类调用。如果您的 node_modules 或应用程序文件夹中有很多 js 文件，这当然会导致构建速度变慢。

在 NativeScript repo 上记录了一个 github 问题，那里有很多关于团队如何处理这个问题的想法，但它仍在进行中 Angular 2未发布，敬请期待
