Expose profile contribution calendar in public API

Our contribution calendar visualization on the user profile currently relies on a semi-private API endpoint: https://gitlab.com/users/#{username}/calendar.json we should consider exposing that into the public API. This would allow people to build/implement visualizations without having to batch-load every single event in a specific timerange. Basically provide access to the aggregated count withing a specified range.

Proposal

The closest API endpoint we have is /users/:id/events (https://docs.gitlab.com/ee/api/events.html#get-user-contribution-events). This gives us the granular data. We need aggregated and we need contributions only. While internally we call that "calendar activities" I think it makes sense to call it what it really is "contributions":

  • Endpoint: /users/:id/contributions Filters:
  • aggregate_by: day, month, year (default: day)
  • since (default: #{Date.current.year}-01-01, first day of january of current year)
  • until (default: #Date.current}, today)

Existing code

Current implementation relies on the following:
