我是 Angular 5 项目的新手。我运行 ng build --prod 生成一个 dist/ 文件夹。

我注意到构建需要很长时间，当我打开我的 dist/ 文件夹时，我看到里面几乎有 98% 无用的东西，比如 SVG、图像等等在..

我如何控制进入我的 dist/ 的内容？

如何优化它？并且只构建我的网站需要的东西？

目前，在我的服务器上构建需要 15 分钟。我如何让它构建得更快？

最佳答案

如果构建速度较慢，您可以使用此版本的 angular cli:

"@angular/cli": "1.7.0-beta.0",

这将我的构建时间从 30 分钟缩短到 3 分钟。

在 Angular 5 中，AOT 和构建优化器默认在产品构建中。

ng build --prod --named-chunks 将 --named-chunks 添加到您的构建命令将为您提供命名 block ，以便您可以更好地分析您的 block ，并更好地增强您导入的内容在每个模块中。 一个例子，也许您正在将整个共享模块导入某个模块，而您只使用该共享模块中的一个东西
