New serverless Pattern - cognito-appsync-bedrock

[proton0210]

This sample pattern demonstrates a secure GraphQL API using AWS AppSync with Amazon Cognito for authentication, which invokes Amazon Bedrock foundation models via an AWS Lambda resolver.

Users authenticate with Cognito, then send prompts via an AppSync mutation. A Node.js Lambda resolver, using the AWS SDK for JavaScript (v3), calls the configured Bedrock model (e.g., Anthropic Claude 3 Sonnet) and returns the response.

This pattern, deployed via AWS CDK, provisions an Amazon Cognito User Pool, an AWS AppSync API, an AWS Lambda function, and necessary IAM roles.

Hi @proton0210 ,
How is this pattern different from http://serverlessland.com/patterns/appsync-bedrock-stream-sam
I understand that you are adding cognito authentication. But that looks like adding two patterns into one.

Hey @biswanathmukherjee ,Great question
Here is it how it is different,

1. It was inspired from this patten APIGW pattern Which is I guess also two patterns in one.
2. Our client requirment in appsync+cognito and not IAM authrorizers which is in the pattern you suggested
3. This Pattern is in CDK(Typescript)
