To celebrate Christmas, we introduce “Will It Comp-Ho-Ho-Hose”, a GraphQL Federation composition game.

Starting from the 12th of December, a new challenge will be unlocked every day leading up to Christmas. The goal of each challenge is to guess whether the two provided subgraphs will compose under the rules of GraphQL federation.

If you think you know Federation, or you want to learn more about its quirks, then this is the game for you!
