AppSync-Pro

This project seamlessly integrates a frontend built with AWS Amplify and a robust backend infrastructure provisioned using AWS CDK. The frontend leverages Amplify libraries to connect with the backend resources, including an AppSync GraphQL API, Amazon DynamoDB tables, and AWS Lambda resolvers. The frontend is hosted on AWS Amplify for easy deployment and scaling.

The backend, defined using AWS CDK, consists of:

• Two DynamoDB tables: "Users" and "Todo"

• Lambda resolvers for CRUD operations on each table

• AWS AppSync for exposing a GraphQL API

• Amazon Cognito User Pool and User Pool Client for authentication and authorization

The Amplify-powered frontend communicates with the AppSync API, which triggers the appropriate Lambda resolvers to perform CRUD operations on the DynamoDB tables. Cognito handles user authentication and authorization, ensuring secure access to the API and backend resources.

Key aspects:

• Frontend built with AWS Amplify and hosted on Amplify

• Backend provisioned using AWS CDK

• AppSync GraphQL API for efficient data communication

• Lambda resolvers for CRUD operations on DynamoDB tables

• Cognito for user authentication and authorization

• Seamless integration between frontend and backend

This integrated solution enables developers to rapidly build and deploy full-stack applications with a serverless backend and a feature-rich frontend, all while leveraging the power and flexibility of AWS services.
