Serverless-ish: Zero to App with Datomic Cloud and GraphQL
summary
Builds a working distributed chat app — GraphQL API, user auth, and BI events — from scratch using Datomic Cloud, AWS AppSync, Amplify and React Native in about 30 minutes. Ions become Lambda-backed resolvers but need a tiny JSON shim because AppSync VTL can’t access the Datomic context directly; current workflow wires resolvers manually in the console but planned @function ARN annotations automate that. Datomic Cloud development tier runs on the order of $1–2/day, and the demo app successfully scales with these managed services.
