Annotation Type JsModule

 @Repeatable(value=JsModule.Container.class)
public @interface JsModule

Annotation for defining JavaScript Module dependencies on a Component class. For adding multiple JavaScript Module files for a single component, you can use this annotation multiple times.

The JavaScript module files should be located:

• inside frontend directory in your root project folder in case of WAR project
• inside META-INF/resources/frontend directory (inside a project resources folder) in case of JAR project (if you are using Maven this is src/main/resources/META-INF/resources/frontend directory).

It is guaranteed that dependencies will be loaded only once.

NOTE: while this annotation is not inherited using the @Inherited annotation, the annotations of the possible parent components or implemented interfaces are read when sending the dependencies to the browser.
