Auction App - Serverless TypeScript Framework

The Auction App leverages the Serverless v.3 Framework, crafted with TypeScript, and architecturally divided into three interconnected services:

1. Auction Service: The core of the app, interfacing through AWS API Gateway. It includes functions for auction operations such as createAuction, getAuctions, getAuction, placeBid, and uploadAuctionPicture. This service is responsible for processing auctions via AWS EventBridge and storing auction data in AWS DynamoDB's AuctionsTable, while auction images are hosted in the S3 AuctionsBucket.
2. Auth Service: Serving as the security gatekeeper, it authorizes API requests using JSON Web Tokens (JWT) with an authorizer function, ensuring secure access control.
3. Notification Service: This component is pivotal for communication, utilising AWS Simple Email Service (SES) to dispatch emails and AWS Simple Queue Service (SQS) for managing mail queues, thereby enabling timely notifications to buyers and sellers upon auction activities.

Each service is meticulously orchestrated through AWS CloudFormation as defined in the serverless.yml file, providing a cohesive, automated, and scalable auction platform. Please refer to the workflow diagram below for a detailed visual representation of the app's architecture and interaction between services.
