CI codecov NuGet Downloads License Platform

Provides integration between MVFC.DataX and the popular FluentValidation library, allowing you to validate data as it streams through your pipelines.

This package is part of the MVFC.DataX suite. For the full documentation and more examples, please check the main repository README.

Installation

dotnet add package MVFC.DataX.Validation

Available Classes

Class Description
FluentTransformer<TInput, TOutput> An IDataTransformer that maps an input item to an output item, then executes a FluentValidation IValidator<TOutput>. Failures automatically translate into DataResult.Failure with specific DataError items populated via the framework's detailed property errors.

API Signatures

public FluentTransformer(
    Func<TInput, TOutput?> mapFunc,
    IValidator<TOutput> validator)

Usage / Example

using FluentValidation;
using MVFC.DataX.Pipeline;
using MVFC.DataX.Validation;

// 1. Define your object and its FluentValidation Validator
public class Order
{
    public int Quantity { get; set; }
    public decimal Price { get; set; }
}

public class OrderValidator : AbstractValidator<Order>
{
    public OrderValidator()
    {
        RuleFor(x => x.Quantity).GreaterThan(0);
        RuleFor(x => x.Price).GreaterThan(0);
    }
}

// 2. Setup standard Readers / DLQs
var reader = new MyDataReader();
var deadLetterWriter = new MyDlqWriter();

// 3. Create the Fluent Transformer using the map function and the rules instance
var validator = new OrderValidator();
var transformer = new FluentTransformer<IncomingData, Order>(
    mapFunc: dto => new Order { Quantity = dto.Qty, Price = dto.Val },
    validator: validator
);

// 4. Orchestrate
var pipeline = PipelineBuilder.ReadFrom(reader)
    .TransformWith(transformer)
    .WriteTo(writer)
    // Any items that failed the rules in OrderValidator will be redirected to the DLQ 
    // seamlessly by the Pipeline Engine
    .OnError(deadLetterWriter)
    .Build();

await pipeline.RunAsync(cancellationToken);
