webpack のチャンク メソッドを使用して、ルート構成の個別のルートに個別のバンドルを生成したいと考えています。これを実現する 1 つの方法は、require.ensure を使用してチャンクの分割ポイントを定義し、ブラウザの要求に応じて非同期的にモジュールをロードすることです。
ここに私が持っているものがあります：
webpack.config.js (実行された npm スクリプトに応じて、dev/prod webpack 構成とマージされます):
var autoprefixer = require('autoprefixer');
var html = require('html-webpack-plugin');
var path = require('path');
var webpack = require('webpack');
var node_modules_dir = path.resolve('./node_modules')
var HappyPack = require('happypack');
module.exports = {
context: path.resolve('./src'),
entry: {
app: ['./scripts/index.js', './styles/index.scss'],
vendor: ['react', 'react-dom', 'react-redux', 'redux','immutable'],
},
module: {
loaders: [
{
test: /\.(jpg|png|gif|json)$/,
loader: 'file',
query: {
name: 'assets/[hash].[ext]',
},
},
{
test: /\.svg$/,
loader: 'happypack/loader?id=svg'
},
],
},
output: {
filename: '[name].js',
path: path.resolve('./build'),
},
plugins: [
new webpack.optimize.OccurrenceOrderPlugin(),
// new webpack.optimize.LimitChunkCountPlugin({maxChunks: 5}),
// new webpack.optimize.MinChunkSizePlugin({minChunkSize: 10000}),
new html({
minify: {
collapseWhitespace: true,
},
template: './index.html',
title: process.env.npm_package_config_title,
}),
new webpack.optimize.CommonsChunkPlugin('vendor','vendor.bundle.js'),
new HappyPack({
id: 'svg',
threads: 5,
loaders: [
'svg-inline'
]
})
],
postcss: function() {
return [
autoprefixer,
];
},
resolve: {
alias: {
assets: path.resolve('./src/assets'),
lib: path.resolve('./src/lib'),
modules: path.resolve('./src/scripts/modules'),
scripts: path.resolve('./src/scripts'),
styles: path.resolve('./src/styles'),
toolbox: path.resolve('./node_modules/react-toolbox'),
vendors: path.resolve('./src/vendors'),
'react-redux': node_modules_dir + '/react-redux/dist/react-redux.min.js',
'redux': node_modules_dir + '/redux/dist/redux.min.js',
'immutable': node_modules_dir +'/immutable/dist/immutable.min.js'
},
extensions: [
'',
'.js',
'.jsx',
'.css',
'.scss',
],
},
toolbox: {
theme: path.resolve('./toolbox/index.scss'),
},
};
webpack.config.dev.js (dev webpack 構成 [上記とマージ]):
var merge = require('webpack-merge');
var webpack = require('webpack');
var path = require('path');
var config = require('./config');
var HappyPack = require('happypack');
var ExtractTextPlugin = require("extract-text-webpack-plugin");
module.exports = merge(config, {
// devtool: 'eval',
devServer: {

ルート.jsx :
[some module imports here]
export default (
<Route component={ PermisionProvider } >
<Route component={ AppProvider } >
<Route component={ SnackbarProvider } >
<Redirect from={ paths.root } to={ localStorage.get('user') ? paths.login : paths.landingPageCities } />
{ /* Landing */ }
<Route onEnter={ _hasPermission.bind(null, 'landingPage') }>
<Route component={ LandingLayout }>
<Route
path={ paths.landingPageCities }
getComponent={(location, callback) => {
require.ensure(['modules/landing_page/smarts/SmartLandingCities'], function (require) {
callback(null, require('modules/landing_page/smarts/SmartLandingCities').default);
}, 'SmartLandingCities');
}}
/>
<Route
path={ paths.landingPageCompanies }
getComponent={(location, callback) => {
require.ensure(['modules/landing_page/smarts/SmartLandingCompanies'], function (require) {
callback(null, require('modules/landing_page/smarts/SmartLandingCompanies').default);
}, 'SmartLandingCompanies');
}}
/>
<Route
path={ paths.aboutUsPage }
getComponent={(location, callback) => {
require.ensure(['modules/landing_page/views/AboutUsPage'], function (require) {
callback(null, require('modules/landing_page/views/AboutUsPage').default);

</Route>
</Route>
{ /* Login */ }
<Route onEnter={ _hasPermission.bind(null, 'login') }>
ブログの投稿やチュートリアルのトーンを読みましたが、すべてここにあるようです。それでも、webpack は、require.ensure を使用するどちらのルートに対しても個別のバンドルを生成していません。
- スマートランディング都市
- SmartLandingCompanies
- 会社概要ページ
アプリ バンドルのサイズは 2 MB で、利用可能なすべてのサイズ縮小方法を既に使用しているため、すでに非常に必死です。
助けてくれてありがとう！
