Is there a way to return the raw content of a component minus its presentation using an out of the box (DXA or CMS/CDS) capability? Preferably, no additional (back end or server-side) development would be required.
I also understand that you can append the querystring variable, "format=json", at the end of a request but it only returns the data model and not the content itself.
?format=json
, you get a JSON representation of the View Model which contains the mapped content/metadata and some additional system metadata. If you just want the raw content of a Component (Presentation), you should use the Content Service.
