Annotation for defining an npm package dependency on a Component class which includes one or more JS modules. The JS Modules can be defined using JsModule annotation on the same Component. For adding multiple npm packages files for a single component, you can use this annotation multiple times.
Declared npm packages will be bundled by flow-maven-plugin in a package.json file, making sure that only one dependency is created.
