Rask.Validation.FluentValidation

FluentValidation for Rask forms and requests, in Rask, a full-stack .NET web framework for teams of any size. Rask.Server and Rask.Wasm reference it for you, so an app has nothing to add.

  • 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).OnSubmit(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.

Package Downloads
Rask.Wasm

The Rask browser host: runs a Rask app's C# components client-side on .NET WebAssembly, with the client halves of the batteries — the mediator and query cache, remote dispatch, accounts, validation and the component kit — on by default. Ships the JS boot scripts, the page shell, and the MSBuild integration that stages them into the published bundle — and, opted in, prerenders every route to static HTML with a sitemap.xml at publish, so a static host serves real pages to visitors and crawlers. Depends on Rask, the shared core.
Rask.Server

The ASP.NET host for Rask, a full-stack .NET web framework, with every battery: database (SQLite, PostgreSQL or SQL Server, picked by Rask:Database:Provider), mediator and query cache, accounts, background jobs, transactional email, cache, file storage, outbox, operator dashboard, durable logs, Web Push, SQLite snapshots and continuous backup. Renders Rask components with live updates over a WebSocket. RaskApp.Create(args).Run<App>() is the whole Program.cs; app.Configure(c => c.Jobs.Off()) is how an app does without one. Depends on Rask, the shared core.
