Building Real-time Serverless GraphQL APIs on AWS with TypeScript and CDK
summary
CDK + TypeScript provisions an AWS AppSync GraphQL API, a Lambda data source, and a pay‑per‑request DynamoDB table in about 40 lines of CDK code and deploys it with cdk deploy. The stack uses api key auth, a Note GraphQL schema with queries, a create Note mutation and an onCreate subscription, Lambda resolvers that put and scan the table, and the demo live codes from scratch and then runs queries mutations and subscriptions successfully.
