Repository Package Examples
This directory contains examples demonstrating how to use the repository package, which provides utilities for implementing the repository pattern in Go applications. The repository pattern abstracts data access logic, making it easier to switch between different data storage implementations and improving testability.
Examples
1. Basic Repository Example
Demonstrates the basic implementation and usage of a repository.
Key concepts:
- Creating a domain entity
- Implementing a repository interface
- Using an in-memory repository implementation
- Performing basic CRUD operations
- Using generics for type-safe repository operations
2. Dependency Injection Example
dependency_injection_example.go
Shows how to use dependency injection with repositories.
Key concepts:
- Injecting repository dependencies
- Decoupling business logic from data access
- Using interfaces for loose coupling
- Testing with mock repositories
- Configuring repositories at runtime
3. Repository Factory Example
Demonstrates how to use a repository factory to create repositories.
Key concepts:
- Creating a repository factory
- Managing multiple repository types
- Centralizing repository creation logic
- Configuring repositories based on application settings
- Handling repository initialization
Running the Examples
To run any of the examples, use the go run command:
go run examples/repository/basic_repository_example.go
