Question

我想在这篇文章的评论部分添加一个问题：Angular 2 AOT vs JIT，但我还没有足够的回复点。

我有一个Angular应用程序，在构建时显示错误，但在dev中没有。我理解在开发中获得快速反馈的愿望，但对于这个应用程序来说，在开发环境中工作了很长时间后，它会导致快速部署的满足问题。而不是ng serve来获取反馈，然后立即执行ng build以确保稍后我将能够部署;是否有我可以添加到ng serve的标志，我会为此做这个？

目前我使用ng serve --aot，但这并不足以显示在构建时失败的错误。现在我的应用程序并不是那么大，所以如果我的ng serve加载速度慢，我会觉得可以接受。

这是我的package.json的片段：

  "url": "XXXXXXX",
  "version": "0.0.1",

    "ng": "ng",

  },

以下是ng服务

的所有构建选项的文档

https://github.com/angular/angular-cli/wiki/serve

对于您的情况，请尝试

ng serve --e=prod

或

ng serve --aot --e=prod

希望这有效。

同时尝试--source-maps = false。这看起来像加速了事情。

我可以向Angular`ng serve`添加什么标志以使hotload显示严格的构建错误
