Angular 2 e enorme pacote webpack.js
Estou tentando entender por que o webpack produz arquivos tão grandes da minha instalação simples do Angular 2.
Eu queria tentar fazer oInício rápido angular de 5 min com webpack.
O início rápido de 5 min inclui nos scripts do fornecedor html 3, os seguintes arquivos (na verdade, inclui 4 arquivos, mas o último é para system.js, que eu não preciso na minha configuração do webpack):
ff$ ls -lh node_modules/angular2/bundles/angular2-polyfills.js node_modules/systemjs/dist/system.src.js node_modules/rxjs/bundles/Rx.js node_modules/angular2/bundles/angular2.dev.js
-rw-r--r-- 1 ff staff 116K Dec 15 21:12 node_modules/angular2/bundles/angular2-polyfills.js
-rw-r--r-- 1 ff staff 1.0M Dec 15 21:12 node_modules/angular2/bundles/angular2.dev.js
-rw-r--r-- 1 ff staff 363K Dec 15 02:44 node_modules/rxjs/bundles/Rx.js
E esses arquivos não são minimizados, um total de cerca de 1,5 MB.
Mas quando executo meu script webpack:
module.exports = {
entry: './src/boot.ts',
output: {
filename: 'bundle.js'
},
devtool: 'source-map',
resolve: {
extensions: ['', '.ts', '.js']
},
module: {
loaders: [
{ test: /\.ts$/, loader: 'ts-loader' }
]
}
};
Isso resulta nos dois arquivos a seguir:
ff$ ls -lh bundle*
-rw-r--r-- 1 ff staff 4.0M Jan 20 19:14 bundle.js
-rw-r--r-- 1 ff staff 4.2M Jan 20 19:14 bundle.js.map
Por que os arquivos do pacote são tão gigantescos quanto os scripts do fornecedor que o início rápido de 5 minutos inclui? Minha parte deste pacote é de apenas alguns bytes ...
Esta é a saída quando executo o comando webpack:
ff$ webpack --display-modules
