E-Commerce Platform

A full-stack e-commerce application with a React frontend and an Express/TypeScript backend. The store supports multiple product categories (electronics, fruits, vegetables) with sorting, pagination, and a clean component-based UI.

The backend follows an OOP architecture with class-based controllers and services, Mongoose lean virtuals for optimized queries, comprehensive request validation via Joi, and structured logging with Winston.

The backend uses an OOP architecture with auto-bind for class method binding, ensuring clean separation between route handlers, controllers, and services. Mongoose lean virtuals are used to attach computed fields without the overhead of full Mongoose documents.

Pagination and sorting are handled through query parameters (limit, page, sort) with support for ascending and descending order via a minus prefix convention (e.g., '-price' for descending). Express-async-handler wraps all route handlers for consistent error propagation.
