Wie Sie richtig bauen ein zu optimieren Winkel 5 Projekt?

Ich bin neu in Winkel-5 Projekt. Ich lief ng build --prod zu generieren dist/ Ordner.

Bemerkte ich, es dauert eine lange Zeit zu bauen, und wenn ich öffnete meine dist/ Ordner, die ich sah, hat es fast 98% Unnützes Zeug drin, wie SVGs, Bilder und so weiter ..

Wie kann ich kontrollieren, was geht in meinem dist/ ?
