NodeTypes.FacebookPost.yaml

'YOUR_PACKAGE:FacebookPost':
  superTypes:
    'TYPO3.Neos:Plugin': TRUE
  ui:
    label: 'Facebook Post'
    group: 'plugins'
    icon: 'icon-facebook-sign'

Settings.yaml

YOUR_PACKAGE:
  facebook:
    pageid: 'YOUR_PAGEID'
    toke: 'YOUR_PAGE_TOKEN'
    limit: '1'

My two cents, maybe the pageid can be configurable in the NodeType for more flexibility. By default, use the setting, or the node property if not empty.

For reference: https://discuss.neos.io/t/show-last-facebook-post-plugin/472

@dfeyer is there a way to display settings in the nodetype? Maybe as placeholder? This would be great from ux perspective. One more thing I would like to add would be a option to show the second, third, ... last post.
