vue-cli2升级到webpack4
修改配置
1.替换插件 extract-text-webpack-plugin，使用 webpack4 推荐使用的插件 mini-css-extract-plugin
build/webpack.prod.conf.js
// ...省略// const ExtractTextPlugin = require('extract-text-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
// ...省略
// ...省略
devtool: config.build.productionSourceMap ? config.build.devtool : false,
performance: {
hints: false
},
// ...省略
// ...省略
// // extract css into its own file
// new ExtractTextPlugin({
// filename: utils.assetsPath('css/[name].[contenthash].css'),
// // Setting the following option to `false` will not extract CSS from codesplit chunks.
// // Their CSS will instead be inserted dynamically with style-loader when the codesplit chunk has been loaded by webpack.
// // It's currently set to `true` because we are seeing that sourcemaps are included in the codesplit bundle as well when it's `false`,
// // increasing file size: https://github.com/vuejs-templates/webpack/issues/1110
// allChunks: true
// }),
new MiniCssExtractPlugin({
filename: utils.assetsPath('css/[name].css'),
chunkFilename: utils.assetsPath('css/[name].[contenthash].css')
}),
// ...省略
new HtmlWebpackPlugin({
filename: process.env.NODE_ENV === 'testing'
? 'index.html'
: config.build.index,
template: 'index.html',
favicon: 'favicon.ico',
inject: true,
minify: {
removeComments: true,
collapseWhitespace: true,
removeAttributeQuotes: true
// more options:
// https://github.com/kangax/html-minifier#options-quick-reference
},
// necessary to consistently work with multiple chunks via CommonsChunkPlugin
// chunksSortMode: 'dependency'
}),
// ...省略
2.去掉 webpack.optimize.CommonsChunkPlugin 相关配置
build/webpack.prod.conf.js
// ...省略 // // split vendor js into its own file
// new webpack.optimize.CommonsChunkPlugin({
// name: 'vendor',
// minChunks (module) {
// // any required modules inside node_modules are extracted to vendor
// return (
// module.resource &&
// /\.js$/.test(module.resource) &&
// module.resource.indexOf(
// path.join(__dirname, '../node_modules')
// ) === 0
// )
// }
// }),
// // extract webpack runtime and module manifest to its own file in order to
// // prevent vendor hash from being updated whenever app bundle is updated
// new webpack.optimize.CommonsChunkPlugin({
// name: 'manifest',
// minChunks: Infinity
// }),
// // This instance extracts shared chunks from code splitted chunks and bundles them
// // in a separate chunk, similar to the vendor chunk
// // see: https://webpack.js.org/plugins/commons-chunk-plugin/#extra-async-commons-chunk
// new webpack.optimize.CommonsChunkPlugin({
// name: 'app',
// async: 'vendor-async',
// children: true,
// minChunks: 3
// }),
// ...省略
3.增加 optimization 配置
build/webpack.prod.conf.js
// ...省略 optimization: {
runtimeChunk: {
name: 'manifest'
},
minimizer: [
new UglifyJsPlugin({
cache: true,
parallel: true,
sourceMap: config.build.productionSourceMap,
uglifyOptions: {
warnings: false
}
}),
new OptimizeCSSPlugin({
cssProcessorOptions: config.build.productionSourceMap
? { safe: true, map: { inline: false } }
: { safe: true }
}),
],
splitChunks: {
chunks: 'async',
minSize: 30000,
minChunks: 1,
maxAsyncRequests: 5,
maxInitialRequests: 3,
name: false,
cacheGroups: {
vendors: {
test: /[\\/]node_modules[\\/]/,
name: 'vendor',
chunks: 'initial',
priority: -10
}
}
}
}
// ...省略
4.修改 utils 配置
build/utils.js
// ...省略// const ExtractTextPlugin = require('extract-text-webpack-plugin')
const MiniCssExtractPlugin = require('mini-css-extract-plugin')
// ...省略
// ...省略
if (options.extract) {
// return ExtractTextPlugin.extract({
// use: loaders,
// fallback: 'vue-style-loader'
// })
return [MiniCssExtractPlugin.loader].concat(loaders)
} else {
return ['vue-style-loader'].concat(loaders)
}
// ...省略
5.增加 mode 配置
build/webpack.base.conf.js
module.exports = {
mode: process.env.NODE_ENV === 'production' ? 'production' : 'development',
context: path.resolve(__dirname, '../'),
// ...省略
6.修改 package.json 依赖版本
