Rask.Validation.FluentValidation

FluentValidation for Rask forms and requests, in Rask, a full-stack .NET web framework for teams of any size. The Rask package references it for you on both the server and the browser.

  • Writing the validator is the registration. A generator finds every AbstractValidator<T> in the app at compile time, and a form asks for the one that validates its model — nothing to declare in the form, nothing to wire in Program.cs.
  • No assembly scan. Registration is emitted as a [ModuleInitializer], so a WebAssembly app uses FluentValidation and still publishes trimmed.
  • Async rules work like sync ones. Each validator is wrapped as an IAsyncFieldValidator, so a MustAsync uniqueness check runs per field; a validator with constructor dependencies is resolved from the scope.
  • Per-keystroke validation of a root-model field runs only that property's rules; submit runs every rule.
  • A validator in a referenced class library is registered explicitly: RaskValidators.Register(typeof(Order), _ => new OrderValidator());

Install

dotnet add package Rask.Validation.FluentValidation

Use

public sealed class OrderValidator : AbstractValidator<OrderModel>
{
    public OrderValidator()
    {
        RuleFor(x => x.Product).NotEmpty();
        RuleFor(x => x.Quantity).GreaterThanOrEqualTo(1).WithMessage("Quantity must be at least 1.");
    }
}

Form.Model(_model).OnValidSubmit(m => _submission = "Ordered")[
    Input.Bind(() => _model.Product),
    Validation.Message.Template(errors => Span.Class("error")[errors[0]]).For(() => _model.Product),
    Input.Bind(() => _model.Quantity),
    Validation.Message.Template(errors => Span.Class("error")[errors[0]]).For(() => _model.Quantity),
    Button.Type("submit")["Order"]
]

Depends on FluentValidation 12.x.

Rask

The one reference a Rask application needs, server or browser. On a server target (net10.0 or net11.0) it brings the ASP.NET host plus every battery — database (SQLite, PostgreSQL or SQL Server, picked by Rask:Database:Provider), mediator, background jobs, transactional email, cache, file storage, outbox, operator dashboard, durable logs, Web Push, and SQLite snapshots and continuous backup — with RaskApp.Create(args) as the entry point. On a browser target it brings the WebAssembly host, the source-generated mediator, the query cache and remote dispatch. Everything referenced is wired and on; app.Configure(c => c.Jobs.Off()) is how an app does without one. Reference Rask.Server for a lean host with no database.
