Medici 1.0.1

Medici

Just another simple mediator implementation library.

How to use it?

First you need to install the according packages from NuGet:

• Medici.Abstractions contains all abstract contracts and interfaces to use in your code
• Medici contains the implementations for the abstractions above
• Medici.DependencyInjection contains basic extensions for your IServiceCollection for proper dependency registration
• Medici.CQRS.Abstractions contains abstract contracts to CQRS and Result patterns
• Medici.Behaviors.Validation contains simple validation pre-processor realisation
• Medici.OpenProcessors contains the implementations for open pre/post behavior

Message types

• IBaseRequest - marker interface for requests
• IRequest - a request message, no return value (including generic variants)
• ICommand - a command message with a Result-pattern response
• IQuery - a query message with a Result-pattern response

Handler types

• IRequestHandler<in TRequest>
• IRequestHandler<in TRequest, TResponse>
• ICommandHandler<in TCommand>
• ICommandHandler<in TCommand, TResponse>
• IQueryHandler<in TQuery>
• IQueryHandler<in TQuery, TResponse>

Pipeline types

• RequestPreProcessorBehavior<TRequest, TResponse>
• RequestPostProcessorBehavior<TRequest, TResponse>

Result pattern types

• Result
• Result<TValue>

Configuration with IServiceCollection

Medici supports Microsoft.Extensions.DependencyInjection.Abstractions directly. To register various Medici services and handlers:

services.AddMedici(cfg => cfg.RegisterServicesFromAssemblyWithType<Program>());

or with an assembly:

services.AddMedici(cfg => cfg.RegisterServicesFromAssembly(typeof(Program).Assembly));

This registers:

• IMedici as transient
• ISender as transient
• IRequestHandler<,> concrete implementations as transient
• IRequestHandler<> concrete implementations as transient

To register pre/post processors:

services.AddMedici(cfg => {
    cfg.RegisterServicesFromAssembly(typeof(Program).Assembly);
    cfg.AddRequestPreProcessor<PingPreProcessor>();
    cfg.AddRequestPostProcessor<PingPongPostProcessor>();
    });

or with implementation type

services.AddMedici(cfg => {
    cfg.RegisterServicesFromAssembly(typeof(Program).Assembly);
    cfg.AddRequestPreProcessor<IPingPreProcessor, PingPreProcessor>();
    cfg.AddRequestPostProcessor<IPingPongPostProcessor, PingPongPostProcessor>();
    });
