Angular 7 没有缩小 html、js、css 文件
Angular 7 is not minifying html, js, css files
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 环境中进行 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！

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。简单修改：
"builder": "@angular-builders/custom-webpack:browser"
至：
"builder": "@angular-devkit/build-angular:browser"
解决了缩小生产环境中所有文件的问题。
如果你想 运行 来自你的 npm start 的 Angular CLI 和随后的 build 脚本，而不像你设置的那样直接使用别名 ng ，您可能需要确保 node_modules 文件夹中的路径正确。它应该是以下内容（并添加您的额外脚本；我无法从您的屏幕截图中复制）：
build: "node node_modules/@angular/cli/bin/ng build --prod"
您也不应该需要那个 --aot 标志，因为 "aot": true 已经涵盖了它。作为单独的测试，您应该 运行 ng build --prod 独立地检查指定输出路径中的包： "outputPath": "dist/project-portal" 我怀疑您用于 npm run build 的 npm 命令不是正确组合并选择正确的 commands/configuration。包没有被缩小的原因很明显，因为 buildOptimizer、optimization 或 aot 标志没有从 angular.json
中正确读取
