aws-lambda-graphql

Apollo Server for AWS Lambda with WebSocket subscriptions support over API Gateway v1 + v2, by Michal Kvasničák. Version 1.0.0-alpha.24 (released 2021) supports only subscriptions-transport-ws protocol, dropping legacy client support. Requires AWS SDK v2, GraphQL 14 or 15, graphql-subscriptions, and ioredis for subscription management. Ships TypeScript types, but the 1.x alpha has breaking changes from 0.13.x. Useful for Serverless GraphQL with real-time subscriptions using API Gateway WebSockets.
