Zerra.Repository.KurrentDB

KurrentDB event store provider for Zerra.Repository, for event-sourced aggregates.

Installation

dotnet add package Zerra.Repository.KurrentDB

Usage

using Zerra.Repository;
using Zerra.Repository.KurrentDB;
using Zerra.Repository.Memory;

// insecure: true for a server without TLS; MemoryEngine is a fallback when KurrentDB isn't running
IEventStoreEngine eventStore = KurrentDBConnectionTest.Test(connectionString, insecure: true, log: log)
    ? new KurrentDBEngine(connectionString, insecure: true)
    : new MemoryEngine();

var busServices = new BusServices();
busServices.AddService<IEventStoreEngine>(eventStore);

An AggregateRoot keeps its state as a stream of events. Each event implements IAggregateEvent and is applied by a public On method:

public sealed class CartAggregate : AggregateRoot
{
    private readonly List<CartItem> items = new();
    public IReadOnlyList<CartItem> Items => items;

    public CartAggregate(Guid customerID, IEventStoreEngine eventStore) : base(customerID, eventStore) { }

    public Task On(CartItemAddedEvent @event)
    {
        items.Add(new CartItem { ProductID = @event.ProductID, Quantity = @event.Quantity });
        return Task.CompletedTask;
    }
}

// in a command handler
var cart = new CartAggregate(command.CustomerID, Context.GetService<IEventStoreEngine>());
await cart.Rebuild();
await cart.Append(new CartItemAddedEvent { ProductID = command.ProductID, Quantity = command.Quantity }, validateEventNumber: true);

validateEventNumber: true rejects the append if another command changed the stream since this instance rebuilt it.
