Installation

To install the package, use the following command in your .NET Core project:

Alternatively, you can add it manually to your .csproj file:

Usage

Here are some basic examples of how to use the library:

Setup

Create your domain objects

// domain.cs

public class TestState 
{
    public required Guid Id { get; set; }
    public string? Test { get; set; }
}

Add the aggregate to the service collection

// program.cs

using StreamWave;
using StreamWave.EntityFramework;

var builder = WebApplication.CreateBuilder(args);

builder.Services.AddAggregate<TestState, Guid>((id) => new TestState() {  Id = id })
            .WithEntityFramework<TestContext, TestState, Guid>()
            .WithApplier<TestEvent>((s, e) =>
            {
                s.Test = e.Field;
                return s;
            });

Use

public async Task HandleAsync(IAggregateManager<TestState, Guid> manager, Guid id)
{
    var aggregate = manager.LoadAsync(id);

    aggregate.Apply(new TestEvent("Update"));

    await manager.SaveAsync(aggregate);
}
