    Exposing the model

    • Go to your IDE or editor and look for the model inside the core module, the model name is BasicModel and should be located inside the models package
    • First, let’s set the model’s adaptables to SlingHttpServletRequest and import the class
      import org.apache.sling.api.SlingHttpServletRequest;
      @Model(adaptables = SlingHttpServletRequest.class)
      
    • Then we need to import and implement the ComponentExporter interface and also define the getExportedType method to return the name for the resource type associated with the basic component
      import com.adobe.cq.export.json.ComponentExporter;
      ...
      public class BasicModel implements ComponentExporter {
          ...
      
          public String getExportedType() {
              return "react-simple-example/components/basic-component";
          }
      
          ...
      }
      
    • Finally import ExporterConstants and the Exporter annotation, add the ComponentExporter as an adapter and define the resourceType. For the exporter set the name as SLING_MODEL_EXPORTER_NAME and the extension as SLING_MODEL_EXTENSION.
      import org.apache.sling.models.annotations.Exporter;
      import com.adobe.cq.export.json.ExporterConstants;
      
      @Model(adaptables = SlingHttpServletRequest.class,
              adapters = {ComponentExporter.class},
              resourceType = BASIC_COMPONENT_RESOURCETYPE)
      @Exporter(name = ExporterConstants.SLING_MODEL_EXPORTER_NAME, extensions = ExporterConstants.SLING_MODEL_EXTENSION)
      
    • Let’s build and deploy the app again
      mvn clean install -PautoInstallPackage -Padobe-public
      
    • Go now to the page edit the component make some changes and click save, the changes get reflected right away
