SharpGrip FluentValidation AutoValidation

Builds

Introduction

SharpGrip FluentValidation AutoValidation is an extension of the FluentValidation library enabling automatic asynchronous validation in MVC controllers and minimal APIs (endpoints). The library FluentValidation.AspNetCore is no longer being maintained and is unsupported. As a result, support for automatic validation provided by this library is no longer available. This library re-introduces this functionality for MVC controllers and introduces automation validation for minimal APIs (endpoints). It enables developers to easily implement automatic validation in their projects.

Installation

Register your validators with the Microsoft DI service container, for instructions on settings that up please see https://docs.fluentvalidation.net/en/latest/di.html.

MVC controllers

For MVC controllers reference NuGet package SharpGrip.FluentValidation.AutoValidation.Mvc (https://www.nuget.org/packages/SharpGrip.FluentValidation.AutoValidation.Mvc).

using SharpGrip.FluentValidation.AutoValidation.Mvc.Extensions;

builder.Services.AddFluentValidationAutoValidation();

Minimal APIs

For minimal APIs (endpoints) reference NuGet package SharpGrip.FluentValidation.AutoValidation.Endpoints (https://www.nuget.org/packages/SharpGrip.FluentValidation.AutoValidation.Endpoints).

Enabling minimal API (endpoint) automatic validation can be done on both route groups and routes.

using SharpGrip.FluentValidation.AutoValidation.Endpoints.Extensions;

var endpointGroup = app.MapGroup("/some-group").AddFluentValidationAutoValidation();
endpointGroup.MapPost("/", (SomeModel someModel) => $"Hello {someModel.Name}");

app.MapPost("/", (SomeOtherModel someOtherModel) => $"Hello again {someOtherModel.Name}").AddFluentValidationAutoValidation();

Configuration

MVC controllers

using SharpGrip.FluentValidation.AutoValidation.Mvc.Extensions;

builder.Services.AddFluentValidationAutoValidation(configuration =>
{
    configuration.DisableDataAnnotationsValidation = true;

    // Only validate controllers decorated with the `FluentValidationAutoValidation` attribute.
    configuration.ValidationStrategy = ValidationStrategy.Annotation;
});
