我有一个小型 React 项目。Webpack 生成的 bundle.js 是 6.3Mb。如何将大小减小到 <2.0Mb？（2Mb 仍然很大但可以接受）。完整的源代码在github
webpack.config.js
module.exports = {
devtool: 'inline-source-map',
entry: [
'./app/components/app.jsx'
],
output: {
path: './public',
filename: 'bundle.js'
},
resolve: {
modulesDirectories: ['node_modules', 'app'],
extensions: ['', '.js', '.jsx', '.scss']
},
module: {
loaders: [
{
test: /\.jsx?$/,
exclude: /node_modules/,
loaders: ['happypack/loader']
},
{
test: /\.scss$/,
loaders: [
'style',
'css',
'autoprefixer?browsers=last 3 versions',
'sass?outputStyle=expanded'
]
},
{
test: /\.(jpe?g|png|gif|svg)$/i,
loaders: [
'url?limit=8192',
'img'
]
}
]
},
plugins: [
new webpack.HotModuleReplacementPlugin(),
new webpack.NoErrorsPlugin(),
new HtmlWebpackPlugin({
title: 'Fullstack Rebel',
template: './app/templates/index_template.ejs'
}),
new HappyPack({
loaders: ['babel?presets[]=react,presets[]=es2015']
})
]
};
