But what is the best approach to render the actual posts? Is there any chance to “configure” the content of the Hugo Posts? Currently I’m just linking to the Ghost posts, which is not exactly what I intended
Hugo still does not support generating content pages from data.
With that said if Ghost gives you the option to output content as a JSON array then the simplest way that I know would be to use JQ to split it into multiple markdown files. You can keep the JSON format within the generated files as it will be their front matter.
There have also been other techniques posted in the forum regarding splitting a JSON into pages.
Also I’m archiving this old topic. I suggest that you track the GitHub issue that was posted above for future developments or if you want to discuss this feature further then please open a new forum topic. Perhaps others have other techniques to share.
