Hi @dh54220 

CRUD operation in node can happen via sling(treat as resource)or node api which can only be done via server side.

You can use server side approach with above api.

@dh54220 you can actually use JCR/Sling APIs in sling models to manipulations to the node properties.

  Resource resource = request.getResourceResolver().getResource("nodePath");
  Session session = resource.adaptTo(Session.class);

  //Create a node that represents the root node
  Node root = session.getRootNode();

  // Store content
  Node adobe = root.addNode("adobe");
  Node aem = adobe.addNode("aem");
  day.setProperty("message", "This is sample message");
  session.save();
  session.logout();

Sling API:

To create node-

Resource myResource = resourceResolver.getResource("/myresource");
Map<String,Object> properties = new HashMap<String,Object>();
properties.put("jcr:primaryType", "nt:unstructured");
properties.put("sling:resourceType", "myapp/components/mytype");
Resource dummy = resourceResolver.create(myResource, "dummy", properties);
resourceResolver.commit();

To remove node-

Resource myResource = resourceResolver.getResource("/myresource");
resourceResolver.delete(myResource);
resourceResolver.commit();

To remove properties-

Resource myResource = resourceResolver.getResource("/myresource");
ModifiableValueMap properties = myResource.adaptTo(ModifiableValueMap.class);
properties.remove("title");
resourceResolver.commit();

Hi @dh54220 

Quick question: Why do you need to delete a node via JS? It is always recommended to do it using JAVA (BE Code) where you can manage the session / resourceresolver in an effective manner to avoid memory leaks.

Here are some examples:

Hope this helps!
