I am trying to create a feature in which I can generically embed a Google Maps or OpenStreetMap using their APIs to draw overlays on the maps into some of my Ghost posts.
I’d prefer to make this a nicer, more generic experience. My first thought was to create a custom card type. However, it seems I would need to make changes to Ghost core in order to do that. My next thought was to modify the theme to load the map in a post when necessary. But then I would still need some way to be able specify the variables/parameters when creating the post, which doesn’t seem to be possible to do without modifying Ghost Core
