我试图获得一个填充了标准文件+ .gz版本的dist文件夹。我webpack.config.js获取了new CompressPlugin({})文件，因此我可以添加压缩插件value_counts。我添加了ejected: false作为最后一个插件，并在.angular-cli.json文件中标记了ng build。
当我运行ng new时，我不会生成任何我期望的.gzip / .gz文件。
我有什么遗漏或做错了吗？完整的webpack文件（主要由const fs = require('fs');

生成：
@angular/cli我正在使用1.4.4 myList = ["One","two","One","tree"];
myNewList = Array.from(new Set(myList ));
。
请注意，我这样做的主要原因是为了改进一些搜索引擎优化建议，因为显然我的vendor.css是600Kb大并且在PageSpeed Ingishts中被指出：您的页面有1个阻止CSS资源。这会导致呈现页面的延迟。它只包含第三方css - 实际上只有bootstrap + font-awesome。除非有其他东西可以防止这种情况，否则我会想到压缩。我还认为Web服务器会自动压缩并提供.gz文件，但我不知道该测试是否适用。
非常感谢任何帮助！感谢
答案 0 :(得分：1)
仅在根webpack.config.js文件上公开处理弹出的应用程序的构建。未被弹出（或设置为ejected: false）的应用程序将完全忽略此webpack.config.js文件。
因此，为了使用gzip压缩文件，您需要使用弹出的应用程序并使用自动添加到package.json的新npm脚本。
而不是'ng build'，现在应该运行：
npm run build
