CRUD Product App

This project includes a sample application that uses Amazon DynamoDB to perform CRUD operations

Interface and Data Flow

The project structure base on interface transportation and transformation. All the data transformation methods are written without using plugins. Interfaces follow

type Interface interface {
	Get(w http.ResponseWriter, r *http.Request)
	Post(w http.ResponseWriter, r *http.Request)
	Put(w http.ResponseWriter, r *http.Request)
	Delete(w http.ResponseWriter, r *http.Request)
	Options(w http.ResponseWriter, r *http.Request)
}

Data flow (internal folder)

routes ➡  handlers ➡ controllers ➡ entities
