I am working on a project that involves using wpapi for nodejs to interact with WordPress posts. I want to update an existing post by adding some new content to its original content. However, I am facing a problem with the content field of the wpapi response. When I use wp.posts() to get the content of a post, I only see the rendered result, which does not include any shortcodes that are present in the WordPress editor. If I simply append some data to this content and use PUT to update the post, I will lose the shortcodes and mess up the formatting of the post. How can I solve this problem? Is there a way to get the raw content of a post as it is in WordPress, or to append content without affecting the shortcodes? I appreciate any help or guidance on this issue. Thank you.
