Recipe API Service

The Recipe API Service is an HTTP API service that provides a set of endpoints to perform CRUD operations on recipe records. The service is built using Go programming language and uses the Gin web framework and GORM ORM library.

Start Service for Testing

To start testing the service, make sure you have Docker and docker-compose installed. Then, start the MySQL container and API service by running the following command:

docker-compose up -d --build
