ResultCommander

Library featuring a command handler pattern for both synchronous and asynchronous operations.

Utilizes Autofac thus Autofac is required and a functional Result approach for failure-prone operations.

Features

• Synchronous and asynchronous command handler definitions
• Definitions and base implementations of commands
• Supports decorators and adapters via Autofac's methods

Description

There are two command types - one that only returns a Result and one that returns an additional entity contained within the Result.

Every handler must return a Result struct which determines whether the operation succedeed or not, handlers may or may not return additional results contained within the Result struct - this is defined by the handled comand.

Installation

Since the library utilizes Autofac, base Autofac configuration is required to use command handlers - Autofac's docs.

To register handlers with the DI container use the ContainerBuilder extension method provided by the library:

builder.AddResultCommander();

To register decorators or adapters use the methods available on ResultCommanderConfiguration like so:

builder.AddResultCommander(options => { options.AddDecorator<FancyDecorator, ISyncCommandHandler<SimpleCommand>(); });

You can register multiple decorators and they'll be applied in the order that you register them - read more at Autofac's docs regarding decorators and adapters.
