“Understanding CQRS: Command and Query Responsibility Segregation Explained”
Summary
CreateUserCommand: Represents the command to create a user.
CreateUserCommandHandler: Handles the command by saving the user to the database.
GetUserQuery: Represents the query to retrieve user details.
GetUserQueryHandler: Handles the query by fetching the user from the database.
UserRepository: Interface for CRUD operations on the User entity.
User: Entity representing a user.
This setup demonstrates a basic CQRS pattern where commands and queries are handled separately. You can enhance this example with more sophisticated error handling, validation, and perhaps integration with other components like an event bus or message queue for more advanced scenarios.
