Dependency Injection Examples
This directory contains examples demonstrating how to use the di package, which provides a container-based dependency injection system for Go applications.
Examples
1. Basic Usage Example
Demonstrates basic usage of the Container type, including:
- Creating a container with context, logger, and configuration
- Getting the context, logger, and configuration from the container
2. Service Container Example
Demonstrates how to use the ServiceContainer type, including:
- Implementing the Repository, DomainService, and ApplicationService interfaces
- Implementing the Config interface with AppConfig and DatabaseConfig
- Creating a service container with dependencies
- Getting repositories, domain services, and application services from the container
3. Generic Container Example
Demonstrates how to use the GenericAppContainer type, including:
- Implementing repository, domain service, and application service initializers
- Creating a generic container with dependencies
- Getting repositories, domain services, and application services from the container
Running the Examples
To run any of the examples, use the go run command:
go run basic_usage_example.go
go run service_container_example.go
go run generic_container_example.go
