PokerNexus is live on the web, the App Store, and Google Play. It's a free social network built for poker players: a feed, forums, direct messages, a directory of US card rooms and their schedules, and equity and ICM calculators whose results post as live cards.

My approach to shaping an Apollo server's GraphQL context around three fields: a resolved current user, a shared data layer, and a fresh set of DataLoaders.
