# Shopping API using Gin, Golang, JWT, Dependency Injection, Unit testing
## Description
This is an shopping cart service implementation in Go (Golang)+ Gin projects.
To create a simple shopping cart service for a small product store and identify, design & implement relevant APIs.
Requirements & User stories
