Angular 7 没有缩小 html、js、css 文件

Question

我在 Angular 7 中的项目有问题。

问题是编译后我在 Chrome 控制台中没有缩小和丑化的文件。在 production 环境中运行项目后，我在控制台中收到以下信息:

Time: 31790ms
chunk {main} main.js (main) 11.3 MB [initial] [rendered]
chunk {polyfills} polyfills.js (polyfills) 539 kB [initial] [rendered]
chunk {runtime} runtime.js (runtime) 6.04 kB [entry] [rendered]
chunk {scripts} scripts.js (scripts) 52.1 kB [entry] [rendered]
chunk {styles} styles.js (styles) 654 kB [initial] [rendered]

如您所见，chunk {main} 有超过 11.3 MB。

进入 Chrome 控制台后，我可以在我的资源中看到这些文件:

不幸的是，只有 scripts.4d10c1b333ada0ab6568.js 被完全缩小了。其余文件未受影响，仍未缩小和丑化。

我试图找到一个解决方案，我发现这应该放在我的 angular.json 文件中:

这也无济于事。这是我的 package.json 文件:

任何人都可以帮助设置我的项目以创建丑化和缩小的文件吗？谢谢!

Answer 1

好的，看来我想通了。 angular.json 文件中的“Builder”选项已更改。这是因为项目中使用了自定义的webpack。简单地改变了:

"builder": "@angular-builders/custom-webpack:browser"

到:

"builder": "@angular-devkit/build-angular:browser"

通过缩小生产环境中的所有文件解决了这个问题。
