# Aragas.Extensions.Options.FluentValidation

[](https://github.com/Aragas/Aragas.Extensions.Options.FluentValidation/actions/workflows/dotnet-format-daily.yml)
[](https://www.nuget.org/packages/Aragas.Extensions.Options.FluentValidation/)
Validates ASP NET Core IOptions at startup via FluentValidation. If the options are not valid,
will throw an exception detailing what's wrong with the options and stop the app's execution.
## Installation
Aragas.Extensions.Options.FluentValidation can be installed using the Nuget Package Manager or the dotnet CLI.
```
# NuGet Package Manager
Install-Package Aragas.Extensions.Options.FluentValidation
```
```
# dotnet CLI
dotnet add package Aragas.Extensions.Options.FluentValidation
```
## Usage
### Standard Usage
Simply change the code you most likely used to do like this:
```csharp
public sealed class SomeOptionsValidator : AbstractValidator
{
public SomeOptionsValidator()
{
RuleFor(x => x.Host).IsUri().IsUrlTcpEndpointAvailable().When(x => x.Enabled);
}
}
public sealed record SomeOptions
{
public bool Enabled { get; init; } = default!;
public string Host { get; init; } = default!;
}
// Old code
services.Configure(ctx.Configuration.GetSection("SomeOptions"));
// New code
services.AddValidatedOptions(ctx.Configuration.GetSection("SomeOptions"));
```
### HttpClient Usage
You can inject and configure a HttpClient in the validator
```csharp
public sealed class SomeHttpOptionsValidator : AbstractValidator
{
public SomeOptionsValidator(HttpClient client)
{
RuleFor(x => x.Url).IsUri().IsUrlAvailable(client).When(x => x.Enabled);
}
}
public sealed record SomeHttpOptions
{
public bool Enabled { get; init; } = default!;
public string Url { get; init; } = default!;
}
// Old code
services.Configure(ctx.Configuration.GetSection("SomeHttpOptions"));
// New code
services.AddValidatedOptionsWithHttp(ctx.Configuration.GetSection("SomeHttpOptions"), httpBuilder =>
{
httpBuilder.ConfigureHttpClient(client =>
{
client.Timeout = TimeSpan.FromSeconds(30);
});
});
```
### Dependency Injection Usage
You can inject a custom dependency and easily retrieve it in the validator
```csharp
public sealed class CustomService
{
public bool IsValid(string str) => str.Contains("Hello World!");
}
public sealed class SomeDIOptionsValidator : AbstractValidator
{
public SomeDIOptionsValidator(CustomService cs)
{
RuleFor(x => x.Url).IsUri().When(x => cs.IsValid(x.ToVerify));
}
}
public sealed record SomeDIOptions
{
public string ToVerify { get; init; } = default!;
public string Url { get; init; } = default!;
}
// Old code
services.Configure(ctx.Configuration.GetSection("SomeDIOptions"));
// New code
services.AddTransient();
services.AddValidatedOptions(ctx.Configuration.GetSection("SomeDIOptions"));
```
