Shopping Cart API

A configurable Restful shopping cart API build using Typescript, Node.js, Express.js, MongoDB, Mongoose, and Joi.
Strictly followed SOLID design principles.
Used clean architecture to ensure that the business logic is independent of external agents.
Databases, frameworks, and the other technologies can easily be changed without disrupting the entire system.
