我试图在我的项目中使用AOT编译,我有7个延迟加载的模块。 AOT编译似乎工作(我的应用程序更快),但我的应用程序的大小比没有AOT编译大1 Mo。当我使用bundle analyzer插件查看发生了什么时,似乎导入了我的共享模块的所有地方(也就是说,几乎在我所有的延迟加载的模块中),它被重新导入,所以有一个共享模块的副本我的每一块!
有人有解决方法吗?
我的共享模块中没有任何提供程序。为了使AOT与延迟加载一起工作,我不得不将此配置用于webpack:
module.exports = function(env) {
return webpackMerge({
plugins: [
new AotPlugin({
tsConfigPath: 'tsconfig-aot.json',
entryModule: helpers.root('src/app/app.module#AppModule')
}),
]
}, commonConfig, {
devtool: 'source-map',
output: {
path: helpers.root('export/dist'),
publicPath: '/',
filename: '[name].[hash].js',
chunkFilename: '[id].[hash].chunk.js'
},
module: {
rules: [
{
test: /\.ts$/,
use: ['@ngtools/webpack']
}
]
},
plugins: [
new webpack.NoEmitOnErrorsPlugin(),
new webpack.optimize.UglifyJsPlugin({ // https://github.com/angular/angular/issues/10618
compress: { warnings: false },
mangle: {
keep_fnames: true
}
}),
new webpack.LoaderOptionsPlugin({
htmlLoader: {
minimize: false // workaround for ng2
}
}),
new ExtractTextPlugin('[name].[hash].css'),
new BundleAnalyzerPlugin()
]
});
};
和普通配置:
module.exports = {
entry: {
'polyfills': './src/polyfills.ts',
'vendor': './src/vendor.ts',
'app': './src/main.ts',
},
resolve: {
extensions: ['.js', '.ts', '.scss']
},
module: {
rules: [
{
test: /\.html$/,
use: 'html-loader?attrs=img:src div:inlineSVG'
},
{
test: /\.(png|jpe?g|gif|svg|woff|woff2|ttf|eot|ico|otf)$/,
use: 'file-loader?name=assets/[name].[hash].[ext]'
},
{
test: /\.scss$/,
exclude: [helpers.root('src', 'app')],
use: ExtractTextPlugin
.extract({
fallback: 'style-loader',
use: [
{ loader: 'css-loader', query: { sourceMaps: true } },
{ loader: 'resolve-url-loader'},
{ loader: 'sass-loader'}
]
})
},
{
test: /\.scss$/,
include: [helpers.root('src', 'app')],
use: [
{ loader: 'raw-loader'},
{ loader: 'resolve-url-loader'},
{ loader: 'sass-loader'}
]
}
]
},
plugins: [
// Workaround for angular/angular#11580
new webpack.ContextReplacementPlugin(
/angular(\\|\/)core(\\|\/)@angular/,
helpers.root('src'), // location of your src
{
// your Angular Async Route paths relative to this root directory
}
),
new webpack.ContextReplacementPlugin(/moment[\/\\]locale$/, /en|fr/),
new webpack.DefinePlugin({
'CONFIG_STORAGE_NAME' : JSON.stringify(CONFIG_STORAGE_NAME),
'process.env': {
'CONFIG_STORAGE_NAME' : JSON.stringify(CONFIG_STORAGE_NAME)
}
}),
new webpack.optimize.CommonsChunkPlugin({
names: ['app', 'vendor', 'polyfills']
}),
new HtmlWebpackPlugin({
template: helpers.root('src', 'index.html')
})
]
};
