	CreateArticle(article *Article) (*Article, error)
	GetUserArticles(userID uint32) (*[]Article, error)
	GetAllArticles() (*[]Article, error)
	GetArticlebyID(ID uint32) (*Article, error)
	DeleteArticle(ID uint32) (bool, error)
}

Repository interface for a layer of abstraction over the db functions

func NewDatabaseRepo

func NewDatabaseRepo(db *gorm.DB) Repository

NewDatabaseRepo adds a layer of abstraction so that everything in the interface Repository can be accessed only via the instance of this function

type Service

type Service interface {
	CreateArticle(article *Article) (*Article, error)
	GetUserArticles(userID uint32) (*[]Article, error)
	GetAllArticles() (*[]Article, error)
	GetArticleByID(ID uint32) (*Article, error)
	DeleteArticle(ID uint32) (bool, error)
}

Service is another abstraction over repository

func NewService

func NewService(r Repository) Service
