Intent.FastEndpoints.Dispatch.Wolverine

Wires FastEndpoints-generated endpoints to Wolverine's IMessageBus, replacing the default in-process CQRS dispatch with Wolverine's InvokeAsync<T> calls.

What This Module Generates

This module is a factory extension only — it does not add new template files. Instead it modifies the output of the Intent.FastEndpoints templates:

  • EndpointTemplateRegistration — groups Commands and Queries (those with HTTP settings) by parent folder and creates one WolverineEndpointModel per CQRS operation, replacing the default endpoint model.
  • WolverineEndpointExtension — hooks into each EndpointTemplate backed by a WolverineEndpointModel, injects an IMessageBus _sender constructor parameter, and emits the appropriate _sender.InvokeAsync<T>(req, ct) dispatch statement inside HandleAsync.

How Dispatch Is Wired

For Commands that return a value, the extension emits a typed invocation and passes the result to a Send.CreatedAtAsync response:

public class CreateProductCommandEndpoint : Endpoint<CreateProductCommand, Guid>
{
    private readonly IMessageBus _sender;

    public CreateProductCommandEndpoint(IMessageBus sender)
    {
        _sender = sender ?? throw new ArgumentNullException(nameof(sender));
    }

    public override void Configure()
    {
        Post("/api/products");
        AllowAnonymous();
    }

    public override async Task HandleAsync(CreateProductCommand req, CancellationToken ct)
    {
        var result = default(Guid);
        result = await _sender.InvokeAsync<Guid>(req, ct);
        await Send.CreatedAtAsync<GetProductByIdQueryEndpoint>(new { id = result }, result, cancellation: ct);
    }
}

For Queries that take no route/query parameters, the extension instantiates the request object inline:

result = await _sender.InvokeAsync<List<ProductDto>>(new GetProductsQuery(), ct);

Prerequisites

This module requires the following modules to be installed:

  • Intent.FastEndpoints — provides the EndpointTemplate this extension hooks into.
  • Intent.Application.Wolverine — registers Wolverine DI services and provides IMessageBus.
  • Intent.Modelers.Services.CQRS — provides the Command/Query model types consumed by the registration class.
