Webpack : How to optimize the generated bundle.js? It's way too big in my case
提问by electrotype
I'm new to Webpack. I try to use Webpack for two main reasons :
我是 Webpack 的新手。我尝试使用 Webpack 主要有两个原因：
- Component management : using
require(...) - Performance : smallest size possible, less requests possible to the server.
- 组件管理：使用
require(...) - 性能：尽可能小，对服务器的请求更少。
But with the application I just started (there are currently something like four React components only ), the bundle.jsfile generated by Webpack is 3.87Mb!!!
但是我刚开始的应用（目前只有四个React组件），bundle.jsWebpack生成的文件是3.87Mb！！！
I'm pretty sure Webpack bundles things I won't ever need. I'd like to know how to optimize the generated file... How do I "debug" Webpack's process?
我很确定 Webpack 捆绑了我永远不需要的东西。我想知道如何优化生成的文件……我如何“调试”Webpack 的进程？
My webpack.config.js:
我的webpack.config.js：
var webpack = require("webpack");
module.exports = {
entry: "./app/bootstrap.js",
output: {
path: __dirname,
publicPath: "/public/",
filename: "bundle.js"
},
module: {
loaders: [
{
test: /\.css$/,
loader: "style!css"
},
{
test: /\.js$/,
exclude: /(node_modules|bower_components)/,
loader: 'babel-loader'
},
{
test: /\.js$/,
include: /vis/,
loader: 'babel-loader'
},
{
test: /\.(png|woff|woff2|eot|ttf|svg|gif|jpg|jpeg|bmp)(\?.*$|$)/,
loader: 'url-loader?limit=100000'
}
]
},
plugins: [
new webpack.ProvidePlugin({
$: "jquery",
jQuery: "jquery",
"window.jQuery": "jquery"
}),
new webpack.optimize.UglifyJsPlugin({minimize: true})
]
};
and package.json:
和package.json：

简单地
webpack --production
or
webpack -p
take a look at http://www.jonathan-petitcolas.com/2015/05/15/howto-setup-webpack-on-es6-react-application-with-sass.html

Add this in your production config file:
将此添加到您的生产配置文件中：
plugins: [
new webpack.DefinePlugin({
'process.env': {
// This has effect on the react lib size
'NODE_ENV': JSON.stringify('production'),
}
}),
new ExtractTextPlugin("bundle.css", {allChunks: false}),
new webpack.optimize.AggressiveMergingPlugin(),
new webpack.optimize.OccurrenceOrderPlugin(),
new webpack.optimize.DedupePlugin(),
new webpack.optimize.UglifyJsPlugin({
mangle: true,
compress: {
warnings: false, // Suppress uglification warnings
pure_getters: true,
unsafe: true,
unsafe_comps: true,
screw_ie8: true
},
output: {
comments: false,
},
exclude: [/\.min\.js$/gi] // skip pre-minified libs
}),
new webpack.IgnorePlugin(/^\.\/locale$/, [/moment$/]), //https://stackoverflow.com/questions/25384360/how-to-prevent-moment-js-from-loading-locales-with-webpack
new CompressionPlugin({
asset: "[path].gz[query]",
algorithm: "gzip",
test: /\.js$|\.css$|\.html$/,
threshold: 10240,
minRatio: 0
})
],
