Conqueror.CQS 0.1.0-beta.21

Conqueror

A set of libraries to powercharge your .NET development.

Open points

• for some features provide code snippets in documentation instead of library (e.g. common middlewares etc.)
• use .ConfigureAwait(false) everywhere
• add null checks to public API methods to support users that do not use nullable reference types

CQS

• create analyzers (including code fixes)
  • missing ConfigurePipeline method (only .NET 6)
  • correct ConfigurePipeline method signature
  • enforce IConfigureCommandPipeline interface to be present command handler types that implement ConfigurePipeline method
  • enforce IConfigureCommandPipeline interface to be present on all command handler types
  • enforce IConfigureCommandPipeline interface to only be present on command handler types
• rename CommandHandlerMetadata to CommandHandlerRegistration and make it public in the abstractions to allow external libraries to use it for server transports
  • same for queries
• add tests for handlers that throw exceptions to assert contexts are properly cleared
• expose command/query and conqueror context objects directly on middleware contexts
• allow registering all custom interfaces in assembly as clients with AddConquerorCommandClientsFromAssembly(Assembly assembly, Action<ICommandPipelineBuilder> configurePipeline)

CQS middleware

• create projects for common middlewares, e.g.
  • Conqueror.CQS.Middleware.Timeout
  • Conqueror.CQS.Middleware.Retry

CQS ASP Core

• rename libraries to Conqueror.CQS.Transport.Http.Client and Conqueror.CQS.Transport.Http.Server.AspNetCore

• delegate route path creation to service

  • in config for client middleware allow setting path convention
    • instruct users to place their route convention into their contracts module to allow both server and client to use the same convention
  • allow path to be set for http commands and queries via attribute
  • allow version to be set for http commands and queries via attribute

• allow complex objects in GET queries by JSON-serializing them

• allow registering commands and queries via DI extension instead of attribute

• add missing tests

  • complex query objects for GET
  • custom serializer settings for read/write
  • null properties
  • null GET parameters
  • throw error on double http service registration

• http server edge cases

  • throw error when duplicate command name is found

Eventing

• make event publisher middleware pipeline configurable
• make event publishing strategy customizable
  • ship two strategies out of the box (parallel and sequential)
    • make them available as service collection extension methods
  • sequential strategy as default
  • handle cancellation in strategy
• add tests for service collection configuration
• for .NET 6 add analyzer that ensures the ConfigurePipeline method is present on all handlers with pipeline configuration interface (including code fix)

Interactive streaming

• implement middleware support
• implement clients and transport infrastructure
• for .NET 6 add analyzer that ensures the ConfigurePipeline method is present on all handlers with pipeline configuration interface (including code fix)

Interactive streaming ASP Core

• refactor implementation to use transport client
• ensure api description works
• add tests for behavior when websocket connection is interrupted (i.e. disconnect without proper close handshake)
  • consider adding explicit message for signaling the end of the stream
• propagate conqueror context
• delegate route path creation to service
• allow setting prefetch options (e.g. buffer size, prefetch batch size)

Reactive streaming

• implement basic version
• implement middleware support
