Gets your posts and comments with one API call by putting comments inside the /posts endpoint. This way there is no need to do separate API call to /wp-json/posts/ID/comments.

1. Unzip and upload the comments-posts-wp-api directory to /wp-content/plugins/
2. Activate the plugin through the 'Plugins' menu in WordPress

Add withcomments in the URI.

Example: /wp-json/posts?withcomments or /wp-json/posts?filter[posts_per_page]=5&withcomments
