Rask.Cqrs

Source-generated, reflection-free CQRS / mediator for .NET. Structure your app as queries, commands and notifications, and dispatch them through a single injectable interface — with every handler wired at compile time, so there is no runtime reflection and no assembly scanning. It publishes clean under the WASM/AOT trimmer.

Standalone: the only dependency is Microsoft.Extensions.DependencyInjection.Abstractions. You do not need the rest of Rask to use it.

Install

dotnet add package Rask.Cqrs

Use

Define messages and their handlers:

public sealed record GetUser(int Id) : IQuery<User>;

public sealed class GetUserHandler(AppDb db) : IQueryHandler<GetUser, User>
{
    public Task<User> HandleAsync(GetUser q, CancellationToken ct) => db.Users.FindAsync(q.Id, ct);
}

Register once, then dispatch — the response type is inferred:

builder.Services.AddRaskCqrs();

// ...
var user = await dispatcher.DispatchAsync(new GetUser(42));   // returns User

ICommand / ICommand<TResult> dispatch the same way; INotification fans out to every handler via PublishAsync.

Pipeline behaviors

Cross-cutting concerns (logging, validation, transactions, caching) are decorators — implement IPipelineBehavior<TRequest, TResult> and register it. Behaviors run in registration order, the first-registered wrapping outermost.

Notes

  • Reflection-free / trim-safe — a Roslyn generator emits the handler registry via a [ModuleInitializer]; nothing is discovered at runtime.
  • Host-agnostic — the same AddRaskCqrs() works on a Rask Server or WASM host, or any plain .NET app.

Package Downloads
Rask.Data

A tiny, provider-agnostic data layer for Entity Framework Core apps: an `Entity<TId>` base (Id, CreatedAt/UpdatedAt audit stamps, and a domain-events collection) plus opt-in marker interfaces (`ISoftDeletable`, `IVersioned`) driven by three `ISaveChangesInterceptor`s — auditing timestamps, transparent soft delete (rewrites a hard delete to a `DeletedAt` stamp behind a global query filter), and after-commit domain-event publication through Rask.Cqrs. `modelBuilder.ApplyRaskConventions()` wires the query filter + optimistic-concurrency token automatically. The base of the `rask generate feature` scaffolder's soft-delete/concurrency/events output.
Rask.Outbox

A transactional outbox for Rask.Data entities: domain events marked `IOutboxEvent` are written to an `OutboxMessage` table in the **same transaction** as the change that raised them (so an event is never lost and never fires for a rolled-back change), then a background `OutboxProcessor` polls the table and publishes them through Rask.Cqrs — at-least-once, crash-safe delivery, all on the app's own database (no broker, no Redis). A source generator registers each event type for reflection-free lookup. Server-side; pairs with Rask.Data.
Rask.Jobs

Durable background jobs for a Rask app, stored in its own database — no broker, no Redis. Enqueue a job (an `IJob`, dispatched to its Rask.Cqrs `ICommandHandler`) and a background `JobProcessor` polls the table and runs it — at-least-once, with exponential-backoff retries. Supports delayed (run-at) jobs and durable interval-recurring jobs. A source generator registers each job type for reflection-free lookup. Server-side; pairs with Rask.Cqrs and EF Core.
