TailwindCSS对于Angular构建来说太大了

Question

当我使用Tailwind用自定义webpack对Angular应用程序进行样式设计时，运行ng build后，styles.js块是巨大的，大约为30mb。这不仅需要很长时间来构建，而且会减慢我的网络应用程序的速度。

清除Tailwind后，styles.js块要小得多(约100kb(，然而30mb似乎大得离谱，甚至没有清除。

这甚至适用于使用https://github.com/notiz-dev/ngx-tailwind，所以我不确定是什么原因导致了这个问题。

tailwind.config.js

module.exports = {
purge: [],
darkMode: false, // or 'media' or 'class'
theme: {
extend: {},
},
variants: {
extend: {},
},
plugins: [],
}

webpack.config.js

module.exports = {
module: {
rules: [
{
test: /.scss$/,
loader: 'postcss-loader',
options: {
postcssOptions: {
ident: 'postcss',
syntax: 'postcss-scss',
plugins: [
require('postcss-import'),
require('tailwindcss'),
require('autoprefixer'),
],
},
},
},
],
},
};

styles.scss

@import 'tailwindcss/base';
@import 'tailwindcss/components';
@import 'tailwindcss/utilities';

有人知道它为什么这么大吗？我知道它没有被清除，但是https://tailwindcss.com/docs/optimizing-for-production声称未压缩的大小小于4mb，为什么我得到了将近7倍？

只需更改tailwind.config.js

module.exports = {
purge: {
enabled: true,
content: ['./src/**/*.{html,ts}']
},
//Other Code
};

然后构建：ng build --prod
