Декларативное динамическое связывание / минификация для MVC?
Есть ли стандартный или подключаемый способ (например, пакет NuGet), чтобы я мог объявить,.js
.css
и в идеале.less
файлы в представлениях MVC и партиалы, где я их использую, и есть ли у них автоматическая комплектация и минимизация во время работы? (a.k.a. "Autobunding ") Я
Мы попробовали встроенный пакет MVC 4. Мне не нравится, что пакеты определяются далеко от того места, где автор страницы может ожидать их найти, вBundleConfig.cs
, Это неработоспособно для не членов команды C #.
Какпример того, что яищу, Вот'S, что я собрал сам, используяSquishIt.

К сожалению, я написал это, поэтому у него много ограничений. Скрипты нене дублируя, требуется простой подход к разграничению пакетов, я недавно добавил некрасивый хак.less
поддержка и т. д.
Существуют ли какие-либо решения для этого?
