ValidationInstaller — Console

Key: Validation
Default Enabled: ✅
Package: SaveApis.Framework.Console

Purpose

Scans assemblies for FluentValidation IValidator<T> implementations and registers them in the DI container for use in hosted services, workers, and other background components.

What It Does

Calls builder.Services.AddValidatorsFromAssemblies(...) with:
- context.SoftwareAssembly — the entry assembly (set via installer.SetSoftwareAssembly())
- all assemblies in context.Assemblies — additional assemblies added via installer.AddAssembly(...)

Dependencies

No dependencies on other installers.

Configuration

No configuration options. Assembly selection is controlled via the InstallerContext.

InstallerContext Setup

(app, installer) =>
{
    installer.SetSoftwareAssembly();                  // scans the entry assembly
    installer.AddAssembly(typeof(SomeExternalType));  // also scan this assembly
}

InstallerContext Extension

installer.WithValidation(bool enabled = true);

Example

public record ProcessJobRequest(Guid JobId, int MaxRetries);

public class ProcessJobRequestValidator : AbstractValidator<ProcessJobRequest>
{
    public ProcessJobRequestValidator()
    {
        RuleFor(x => x.JobId).NotEmpty();
        RuleFor(x => x.MaxRetries).InclusiveBetween(1, 10);
    }
}

// In a hosted service:
public class JobWorker(IValidator<ProcessJobRequest> validator) : BackgroundService
{
    protected override async Task ExecuteAsync(CancellationToken stoppingToken)
    {
        var request = new ProcessJobRequest(Guid.NewGuid(), 3);
        var result = await validator.ValidateAsync(request, stoppingToken);
        if (!result.IsValid)
        {
            // handle validation errors
        }
    }
}
