📄 Overview

The project consists of a frontend built with React and Chakra UI for fast UI development. The chat interface supports real-time messaging using AWS Chime Messaging. Messages are rendered using React Virtuoso for virtualized lists, ensuring performance with large message histories.

For authentication, AWS Cognito handles user management, and temporary AWS credentials are issued via Cognito Identity Pool. A Lambda function is triggered upon user confirmation to create a corresponding AWS Chime user, enabling messaging capabilities.

Terraform is used for infrastructure as code (IaC), simplifying AWS resource management. This ensures easy setup, modification, and teardown of cloud resources.
