AWS CDK: Lambda S3 Access with Reusable Role

This mini-project demonstrates how to connect an AWS Lambda function to an S3 bucket using a custom, reusable IAM execution role with AWS CDK (TypeScript).

You’ll see:

• How to create an S3 bucket with a unique name.
• How to create a Lambda function (Node.js) that reads from S3.
• How to create a custom IAM role, grant it S3 and CloudWatch permissions, and assign it to the Lambda.
• How to output key resource names for easy CLI use or debugging.

💻 Stack Overview

• S3 Bucket: Stores analytics data. Name includes account & region for uniqueness.
