graphql-lambda-subscriptions

GraphQL subscriptions on AWS Lambda using API Gateway WebSockets and DynamoDB, compatible with the graphql-ws protocol. Version 6.0.0 is stable with no recent changes. It provides a serverless alternative to graphql-ws, eliminating the need for a persistent WebSocket server. Key differentiators: uses only DynamoDB, API Gateway, and Lambda; supports optional step functions for ping/pong; offers lifecycle hooks for subscriptions; and is TypeScript-compatible. Release cadence is irregular, with the last release over a year ago.
