Developist.Core.Cqrs

A lightweight in-process CQRS library simplifying command, query, and event handling.

Messages and Handlers

Define messages using simple interfaces:

• ICommand: For command messages.
• IQuery<TResult>: For query messages.
• IEvent: For notification-style messages.

Create message handlers by implementing corresponding interfaces:

• ICommandHandler<T>: For handling commands.
• IQueryHandler<T, TResult>: For handling queries.
• IEventHandler<T>: For handling events.

Dispatching

Easily dispatch messages to handlers:

• Use the dispatcher to route messages to their respective handlers.
• Automatic handler registration through dependency injection.
• No manual handler registration needed.

Interception

Enhance message processing with interceptors:

• Modify or enhance command/query behavior by forming a customizable pipeline with execution order.
• Use the PipelinePriorityAttribute to specify interceptor order.
