我正在测试我的生产版本，我收到了这个警告
WARNING in entrypoint size limit: The following entrypoint(s) combined asset size exceeds the recommended limit (244 KiB). This can impact web performance.
Entrypoints:
main (3.65 MiB)
main.css
main.js
我该怎么做才能让它变小，或者我应该把它分成更小的块？
如果有怎么办？
这是我为我的 webpacks 得到的
webpack.prod
const merge = require("webpack-merge");
const MiniCssExtractPlugin = require("mini-css-extract-plugin");
const OptimizeCSSAssetsPlugin = require("optimize-css-assets-webpack-plugin");
var BundleAnalyzerPlugin = require('webpack-bundle-analyzer').BundleAnalyzerPlugin;
const common = require("./webpack.common.js");
module.exports = merge(common, {
// Provides process.env.NODE_ENV with value production.
// Enables FlagDependencyUsagePlugin, FlagIncludedChunksPlugin,
// ModuleConcatenationPlugin, NoEmitOnErrorsPlugin, OccurrenceOrderPlugin,
// SideEffectsFlagPlugin and UglifyJsPlugin.
mode: "production",
devtool: "source-map",
// see https://webpack.js.org/configuration/optimization/
optimization: {
// minimize default is true
minimizer: [
// Optimize/minimize CSS assets.
// Solves extract-text-webpack-plugin CSS duplication problem
// By default it uses cssnano but a custom CSS processor can be specified
new OptimizeCSSAssetsPlugin({})
]
},
module: {
rules: [
{
test: /\.(sa|sc|c)ss$/,
// only use MiniCssExtractPlugin in production and without style-loader
use: [MiniCssExtractPlugin.loader, "css-loader", "sass-loader"]
}
]
},
plugins: [
// Mini CSS Extract plugin extracts CSS into separate files.
// It creates a CSS file per JS file which contains CSS.
// It supports On-Demand-Loading of CSS and SourceMaps.
// It requires webpack 4 to work.
new MiniCssExtractPlugin({
filename: "[name].css",
chunkFilename: "[id].css"
}),
new BundleAnalyzerPlugin()
]
});
webpack.common
const path = require("path");
const HtmlWebpackPlugin = require("html-webpack-plugin");
const CleanWebpackPlugin = require("clean-webpack-plugin");
const webpack = require('webpack');
module.exports = {
entry: ["babel-polyfill", "./src/index.js"],
output: {
// filename and path are required
filename: "main.js",
path: path.resolve(__dirname, "dist")
},
module: {
rules: [
{
// JSX and JS are all .js
test: /\.js$/,
exclude: /node_modules/,
use: {
loader: "babel-loader",
}
},
{
test: /\.(eot|svg|ttf|woff|woff2)$/,
use: [
{
loader: 'file-loader',
options: {}
}
]
}
]
},
plugins: [
new CleanWebpackPlugin(["dist"]),
new HtmlWebpackPlugin({
template: "./src/index.html"
}),
new webpack.IgnorePlugin(/^\.\/locale$/, /moment$/),
]
};
通过使用 BundleAnalyzerPlugin，我只需从 Font Awesome 导入我需要的字体并忽略所有时刻的本地人，就可以减少大约 1mb。
我仍然认为它可以更小。
