[英]How to use uglifyjs to minify and compress css/scss in webpack/vue cli?
我有帶有 cli 的 vue 應用程序。 我想使用uglifyjs 插件。
所以我將此代碼添加到我的 vue.config.js 中:
configureWebpack: {
optimization: {
minimizer: [
new UglifyJsPlugin({
uglifyOptions: {
warnings: false,
parse: {},
compress: {},
mangle: true, // Note `mangle.properties` is `false` by default.
output: null,
toplevel: false,
nameCache: null,
ie8: false,
keep_fnames: false,
},
}),
],
},
我想壓縮 *.scss 和 *.vue 文件中存在的所有 css。 如何配置UglifyJsPlugin
來壓縮和縮小? 例如,我有這個選擇器: .some-thing
輸出應該是: .x
。
這里有什么不起作用:
應用程序
<template>
<div class="some">appp</div>
</template>
<script>
export default {
name: 'App',
};
</script>
<style lang="scss" scoped>
.some { border:1px solid red;}
</style>
我運行這個命令(哪個 vue cli build):
npm run build (for production).
我的完整 vue.config.js:
const merge = require('lodash/merge');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
module.exports = {
css: {
loaderOptions: {
sass: {
prependData: `
@import "~@/sass/mixins.scss";
`,
},
},
},
configureWebpack: {
optimization: {
minimizer: [
new UglifyJsPlugin({
uglifyOptions: {
warnings: false,
parse: {},
compress: {},
mangle: true, // Note `mangle.properties` is `false` by default.
output: null,
toplevel: false,
nameCache: null,
ie8: false,
keep_fnames: false,
},
}),
],
},
},
};
css/app.css 的內容如下:
.some[..] {border:1px solid red;}...
** 編輯 ** @Tony Ngo 回答后:
const LodashModuleReplacementPlugin = require('lodash-webpack-plugin');
const UglifyJsPlugin = require('uglifyjs-webpack-plugin');
const OptimizeCSSAssetsPlugin = require('optimize-css-assets-webpack-plugin');
const CompressionPlugin = require('compression-webpack-plugin');
module.exports = {
css: {
loaderOptions: {
sass: {
prependData: `
@import "~@/sass/mixins.scss";
`,
},
},
},
configureWebpack: {
optimization: {
minimizer: [
new UglifyJsPlugin({
cache: true,
parallel: true,
sourceMap: false,
extractComments: 'all',
uglifyOptions: {
compress: true,
output: null,
},
}),
new OptimizeCSSAssetsPlugin({
cssProcessorOptions: {
safe: true,
discardComments: {
removeAll: true,
},
},
}),
],
},
plugins: [
new CompressionPlugin({
test: /\.(js|css)/,
}),
new UglifyJsPlugin(),
],
},
chainWebpack: (config) => {
// nothing here yet
},
};
.some
仍然在我的 app.css 包中。 我想縮小和壓縮,所以我希望像.x
你可以在這里查看我的完整代碼
這是您丑化代碼所需的基本設置
module.exports = {
optimization: {
minimizer: [
new UglifyJsPlugin({
cache: true,
parallel: true,
sourceMap: false,
extractComments: 'all',
uglifyOptions: {
compress: true,
output: null
}
}),
new OptimizeCSSAssetsPlugin({
cssProcessorOptions: {
safe: true,
discardComments: {
removeAll: true,
},
},
})
]
},
plugins: [
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename: "[id].css"
}),
new CompressionPlugin({
test: /\.(js|css)/
}),
new UglifyJsPlugin(),
],
module: {
rules: [{
test: /\.scss$/,
use: [
'style-loader',
MiniCssExtractPlugin.loader,
{
loader: "css-loader",
options: {
minimize: true,
sourceMap: true
}
},
{
loader: "sass-loader"
}
]
},
{
test: /\.(js|jsx)$/,
exclude: /node_modules/,
loader: ["babel-loader", "eslint-loader"]
},
{
test: /\.(jpe?g|png|gif)$/i,
loader: "file-loader"
},
{
test: /\.(woff|ttf|otf|eot|woff2|svg)$/i,
loader: "file-loader"
}
]
}
};
