Description

GraphQL API responsible for returning the workspace statistics for the data dashboard. Steps:

• Implement GraphQL field under TeamType, which returns an object of a new GraphQL type TeamStatisticsType
• Implement a library TeamStatistics, which is exposed in GraphQL by the type TeamStatisticsType, which implements one method for each data point
• Implement the logic for each data point exposed in the GraphQL API:
  • number_of_articles_created_by_date
  • number_of_articles_updated_by_date
  • number_of_explainers_created
  • number_of_fact_checks_created
  • number_of_published_fact_checks
  • number_of_fact_checks_by_rating
  • top_articles_sent
  • top_articles_tags
  • number_of_messages
  • number_of_conversations
  • number_of_messages_by_date
  • number_of_conversations_by_date
  • number_of_search_results_by_type
  • average_response_time
  • number_of_unique_users
  • number_of_total_users
  • number_of_returning_users
  • number_of_subscribers
  • number_of_newsletters_sent
  • number_of_newsletters_delivered
  • top_media_tags
  • top_requested_media_clusters
  • number_of_media_received_by_type
  • number_of_articles_sent
