ユースケース/要件/問題：彼らは、複数のangular2のアプリで再利用することができるように
ホストベンダーとpolyfillsがCDNで別々にバンドル。ベンダーとポリフィルバンドルは、webpack 2を使用して別々のangle2アプリとして構築され、結果として得られるバンドルはCDNでホストされ、N個のangular2アプリによって再利用されます。建物とホスティングベンダーバンドル別途
私は何ですか？
angular2 webpack2 starterのスタータープロジェクトを使用してwebpackで良いサイズのang2プロジェクトを作成しました。プロードモードでビルドして、うまく動作します。 私たちは社内のCDNを持っているので、ベンダーとポリフィルドを別々にホストすることに決めました。これは、ホストされているときに他のangular2プロジェクトでも再利用できます。
ベンダーとポリフィルを具体的に構築するang2プロジェクトを作成しました
私は何をコードしましたか？
基本的には、私はウェブパックの設定のどこかで迷惑をかけると信じています。 これは、良いサイズのangular2プロジェクトから私のwebpack.common.js
