| # We are changing absithe here so that it expects maps with string keys instead | |
| # of maps with atom keys when it resolves :user object | |
| # | |
| # Out of the box absinthe is optimized for using with something like ecto | |
| # that would normally use an ecto schema (which have atom keys). | |
| # Instead we are working with api responses and we don't need | |
| # the overhead converting our maps to maps with atom keys. | |
