Ham*_*med 6 css webpack webpack-4 mini-css-extract-plugin
我在删除webpack 4中未使用的CSS时遇到问题.似乎大多数CSS纯化插件都依赖于提取文本插件,该插件未针对版本4进行更新.
这是我的命令:
node_modules/.bin/webpack --mode = development --env.operation = separateCSS
要么
node_modules/.bin/webpack --mode = development --env.operation = bundleCSS
这是我的webpack.config.js的一部分:
rules: [
// Loader for SASS files
{
test: /\.s[ac]ss$/,
use: [
// Use IIFE to choose how to emit the CSS: 1. Extract as separate file 2: Bundle with the JS file
(() => { return env.operation == "separateCSS" ? MiniCssExtractPlugin.loader : 'style-loader'; })(),
{ loader: 'css-loader', options: { importLoaders: 1, url: true } },
{
loader: 'postcss-loader',
options: {
ident: 'postcss',
plugins: [
// Write future-proof CSS and forget old preprocessor specific syntax. Use the latest CSS syntax today with cssnext.
// It transforms CSS specs into more compatible CSS so you don’t need to wait for browser support.
// It parses CSS and add vendor prefixes to CSS rules using values from Can I Use.
// https://github.com/MoOx/postcss-cssnext
require('postcss-cssnext')()
]
}
},
'sass-loader'
]
}
],
plugins: [
new MiniCssExtractPlugin({
filename: "../css/[name].css"
})
]

有谁知道如何修改我的配置文件,以便webpack可以删除未使用的CSS?
您是否考虑过使用名为uncss的东西。有一个 webpack 插件。它将查看您的所有 CSS 并将其与您的 HTML 进行比较,并删除您不使用的任何内容。
