Intent.AspNetCore.Controllers.Dispatch.Wolverine

Wires ASP.NET Core controllers generated by Intent Architect to dispatch commands and queries through Wolverine's IMessageBus, replacing the default MediatR dispatch with Wolverine's InvokeAsync pattern.

What This Module Generates

This module does not introduce new template files. It hooks into the existing ControllerTemplate from Intent.AspNetCore.Controllers via a factory extension:

• WolverineControllerDispatchExtension — factory extension that finds every generated controller whose model is a CqrsControllerModel, injects IMessageBus _sender via the constructor, and replaces the dispatch call in each action method with _sender.InvokeAsync or _sender.InvokeAsync<T>.
• ImplicitControllerTemplateRegistration — groups commands and queries that carry HTTP settings by their parent folder element, creating one controller per group.

Controller Dispatch

For commands that return a result, the generated action uses the typed overload:

var result = await _sender.InvokeAsync<Guid>(command, cancellationToken);

For void commands (no return type), the non-generic overload is used:

await _sender.InvokeAsync(command, cancellationToken);

Constructor Injection

IMessageBus is injected through the controller constructor, not as an action-method parameter:

public class ProductsController : ControllerBase
{
    private readonly IMessageBus _sender;

    public ProductsController(IMessageBus sender)
    {
        _sender = sender;
    }
}

Generated Controller Shape

A typical controller generated by this module looks like:

[ApiController]
[Route("api/[controller]")]
public class ProductsController : ControllerBase
{
    private readonly IMessageBus _sender;

    public ProductsController(IMessageBus sender)
    {
        _sender = sender;
    }

    [HttpPost]
    public async Task<ActionResult<Guid>> CreateProduct(
        [FromBody] CreateProductCommand command,
        CancellationToken cancellationToken = default)
    {
        var result = await _sender.InvokeAsync<Guid>(command, cancellationToken);
        return CreatedAtAction(nameof(GetProductById), new { id = result }, result);
    }

    [HttpGet("{id}")]
    public async Task<ActionResult<ProductDto>> GetProductById(
        [FromRoute] Guid id,
        CancellationToken cancellationToken = default)
    {
        var result = await _sender.InvokeAsync<ProductDto>(new GetProductByIdQuery(id: id), cancellationToken);
        return result == null ? NotFound() : Ok(result);
    }
}

Command Instantiation

When a command or query model has a parameterized constructor, the generated call uses constructor syntax:

new GetProductByIdQuery(id: id)

When no parameterized constructor is present, object initializer syntax is used instead:

new GetProductByIdQuery { Id = id }
