Milleks on projekti repository kaust mõeldud?

In Go projects, the repository directory is typically used to implement the Data Access Layer. It contains code responsible for interacting with the database or other data stores.

Main tasks of the repository directory:

• Abstracting data access logic from business logic.
• Providing interfaces for CRUD operations (create, read, update, delete).
• Facilitating testing by allowing repositories to be replaced with mocks.

Example of a repository interface:

package repository

type User struct {
    ID   int
    Name string
}

type UserRepository interface {
    GetByID(id int) (*User, error)
    Save(user *User) error
}

This way, the repository directory helps structure the project and separate data handling logic from the rest of the code.
