NPv.CQS.Infrastructure

Infrastructure for declarative execution of commands and queries in CQS-based applications.
Includes dispatcher, default implementations, and Autofac integration.

โœจ Overview

NPv.CQS.Infrastructure provides essential building blocks for executing commands and queries defined using NPv.CQS.Abstractions.

It includes:

  • A dispatcher for resolving and executing handlers,
  • Default implementations of ICommandBuilder and IQueryBuilder,
  • Autofac module for automatic handler registration by namespace.

This package is intended for the application or composition root layers, where behaviors are wired and executed.

๐Ÿ”ง Key Features

  • ๐Ÿ“ฆ Built-in ICommandBuilder and IQueryBuilder implementations
  • ๐Ÿ“ก Centralized IDispatcher for command and query execution
  • ๐Ÿงฉ CQSModule for seamless Autofac integration via namespace scanning
  • โš™๏ธ Type-safe, convention-based resolution and orchestration of handlers
  • ๐Ÿ’ก Compatible with all abstractions from NPv.CQS.Abstractions

๐Ÿ“ฆ Installation

dotnet add package NPv.CQS.Infrastructure

๐Ÿงช Usage Example

1. Register Autofac Module (in Program.cs)

builder.Host.UseServiceProviderFactory(new AutofacServiceProviderFactory());

builder.Host.ConfigureContainer<ContainerBuilder>(container =>
{
    container.RegisterModule(new CQSModule("YourApp.HandlersNamespace"));
});

2. Execute a Command Declaratively

await _commandBuilder.ExecuteAsync(new CreateOrderCommandContext(orderId, amount));

3. Execute a Query Declaratively

var order = await _queryBuilder.For<Order>().With(new FindById(orderId));

No need to resolve handlers manually โ€” the infrastructure handles it based on context and criterion types.

๐Ÿงฉ Components Included

Component Purpose
CQSModule Autofac module for scanning and registering command/query handlers
Dispatcher Central abstraction for invoking commands and queries via builders
CommandBuilder Resolves and executes ICommand<TContext> for a given context
QueryBuilder Resolves and executes IQuery<TCriterion, TResult> for a given criterion
Default implementations Internal infrastructure for resolving types and linking abstractions
