ReValidator.Validation.MinimalApi

Dynamic, rule-based request validation for ASP.NET Minimal APIs using Endpoint Filters.

This package integrates ReValidator into Minimal APIs, allowing request DTOs to be validated using runtime-loaded rules instead of compiled validators or attributes.

Installation

dotnet add package ReValidator.Validation.MinimalApi

builder.Services.AddReValidator();

Basic usage

  1. Define a model
public class Person
{
    public string? Name { get; set; }
    public int Age { get; set; }
}
  1. Register a validation rule

Rules are injected at runtime and can be changed without redeploying the application.

app.Services.ApplyReconfiguration(
    new DynamicReconfiguration
    {
        RuleName = "NameRequired",
        PropertyName = "Name",
        ErrorMessage = "The \"{PropertyName}\" is required",
        Expression = "x => !string.IsNullOrWhiteSpace(x.Name)",
        FullPathToModel = typeof(Person).FullName
    });
  1. Enable validation on an endpoint

Validate a specific request type:

app.MapPost("/persons", (Person person) => Results.Ok())
   .AddReValidator<Person>();

Or validate all request DTOs on the endpoint:

app.MapPost("/persons", (Person person) => Results.Ok())
   .AddEndpointFilter<ReValidatorFilter>();

Validation result

If any rule fails, ReValidator returns:

422 Unprocessable Entity

With a standard validation payload:

{
  "errors": {
    "Name": [
      "The \"Name\" is required"
    ]
  }
}

When validation runs

Validation is executed only when:

  • .AddReValidator<T>() is applied
  • .AddEndpointFilter<ReValidatorFilter>() is used

If no rules are registered for a model type, validation is skipped.

What this package provides

  • Minimal API integration for ReValidator
  • Endpoint filters for request validation
  • Runtime rule execution using expressions
  • Standardized HTTP 422 responses

ReValidator is designed for systems where validation rules must be managed outside of code and updated at runtime without redeployment.
