In AEM 6.0 version, as part of social communities’ project AEM implemented a handlebar script files in place of JSP scripts. As part of this project AEM SCF community implemented a handle bar engine which in turn uses handlebars.java(jknack) library to compile and execute handlebar templates. Example: Let’s say I have a component called helloworld and the path of component is /apps/mysite/components/content/helloworld. Below three steps we need to do to implement header component. 1. Register a HBS component To register HBS component we need to implement SocialComponentFactory interface and then we need to override methods. In “getSupportedResourceType” method we need to return component path to register it to handlebar engine. Once we register a component json response will automatically available to handlebar script file. Example: The key aspect is to override getSocialComponent method(Resource).
