SWC (Speedy Web Compiler) is a lightning-fast JavaScript/TypeScript compiler, but it doesn't support Angular even when using JIT (Just-In-Time) compilation because Angular requires some additional transformations:
-
Component.templateUrl=>Component.template -
Component.styleUrls&Component.styleUrl=>Component.styles - Additional metadata for
input(),output(),viewChild(), etc...
That is when this plugin comes in. It is a SWC plugin that adds support for Angular.
Note that this plugin is not a replacement for the Angular compiler, and it won't work without the JIT compiler. This means that while it is suitable for testing, it shouldn't be used to build production applications.
