How to create a Generic Repository in Golang?

The generic Repository facilitates the grouping of common database operations in the system. It is essential to have this structure.

Steps to follow:

• Create an Entity interface that will be used in the Repository.
• Define the basic operations (Create, Read, Update and Delete).
• Define other important operations (Count, Lirst, Last and others).
• For better organization, place it in a /shared or /common directory.

Procedure:

• The repository incorporates the Repository base via composition.
• The Repository constructor must initialize the BaseEntity.
• The Repository implements only the specific functions according to its purpose.
• The repository can override an existing method in the base.

Some Relationships:

• Entity and Entity Interface: Implementation or realization.
• Entity (Concrete) and BaseEntity: Composition.
• Repository and Base Repository: Composition.
• Repository and Entity: Dependency.

Advantages:

• Organization.
• Centralization of logic.
• Reuse of the repository.
• Scalability, making it easy to add or remove functions.
