oEmbed
The oEmbed resolver requires a providers.json to be loadable from the application.
The oembed-providers-path config option can be set to change where the file is loaded from (defaults to ./data/oembed/providers.json).
If Facebook and Instagram oEmbed providers are in your providers.json file, you can specify the oembed-facebook-app-id and oembed-facebook-app-secret config options to grant Authorization for those requests, giving you rich data for Facebook and Instagram posts.
