Я пытаюсь создать микрофронт, используя единую структуру SPA, я использую одно угловое приложение и выполнил единую конфигурацию SPA. Когда я пытаюсь загрузить приложение angular, я вижу размер файла main.js как 9 МБ, что слишком велико для простого примера приложения с одним компонентом

Помогите мне уменьшить размер файла, заранее спасибо

Вам следует попробовать использовать анализатор пакетов, такой как source-map-explorer. Это покажет вам, что занимает все пространство.

Установите пакет:

 npm i -g source-map-explorer
 

Используйте его для анализа вашего приложения:

 ng build --configuration production --sourceMap=true amp;amp; source-map-explorer dist\main-*.*.js
