SocialTalents HP Toolkit

HP = means 'HelPer'

Repository structure

Samples.Console - Sample implementation

SocialTalents.Hp.Events.net45 - Inversion of Events handing (for .net Framework 4.5+)

SocialTalents.Hp.Events.nettandard - Copy for .netStandard (copis all files in pre-build step)

SocialTalents.Hp.MongoDb - Helper classes for mongodb (TBD)

SocialTalents.Hp.UnitTests - Tests for all SocialTalents.Hp.* projects

Usage

Publish events

EventBus.Publish<TEvent>(eventInstance, sender);

TEvent - identify workflow queue

eventInstance - event to handle (may be child class of TEvent)

sender - (ussually this) Any class which declares ICanPublish< TEvent > interface

Subscribing to events

Using lambda functions:

EventBus.Subscribe<TEvent>((eventInstance) => { do something with eventInstance });

using handler function:

void eventHandler(TEvent eventInstance) { }
...
EventBus.Subscribe<TEvent>(eventHandler);

using interface:

class ServiceToHandleEvents: ICanHandle<TEvent> {
   public void Handle(TEvent eventInstance) { ... }
}
...
EventBus.Subscribe<TEvent>(serviceToHandleEvents);

Modifying handler calling strategy

Multiple handlers are ok:

EventBus.Subscribe<TEvent>(handler1);
EventBus.Subscribe<TEvent>(handler2);
EventBus.Subscribe<TEvent>(handler3);

Async handling:

EventBus.Subscribe(handler.Async());

Fail strategy:

EventBus.Subscribe(handler.AddOnFail<TEvent, TException>(onFailHandler));

Retry strategy (5 times, with 30 seconds delay):

EventBus.Subscribe(handler.Retry(5, TimeSpan.FromSeconds(30)));

Strategies can be combined, for example OnFail with Async:

EventBus.Subscribe(handler.AddOnFail<TEvent, TException>(onFailHandler).Retry(5).Async());

Requirements

Minimal dotnet framework required: 4.5.1 (.NET Standard 1.2) Understanding .NET Standart vs .NET Framework

Works with .NET Core and .NET Framework
