Typely.Core 0.1.2-alpha

Typely lets you create types easily with a fluent API to embrace Domain-driven design and value objects.

Example

public class TypesConfiguration : ITypelyConfiguration
{
    public void Configure(ITypelyBuilder builder)
    {
        builder.OfInt().For("Votes");        
        builder.OfString().For("Code").Length(4).NotEqual("0000");
        
        builder.OfString()
            .For("UserId")
            .WithNamespace("UserAggregate")
            .WithName("Owner identifier")
            .NotEmpty()
            .NotEqual("0").WithMessage("{Name} cannot be equal to {ComparisonValue}.").WithErrorCode("ERR001")
            .MaxLength(20);

        builder.OfString()
            .For("Monday")
            .AsClass()
            .WithName(() => LocalizedNames.Moment)
            .MinLength(1).WithMessage(() => LocalizedMessages.MinLengthCustom)
            .MaxLength(20).WithMessage(() => LocalizedMessages.MaxLengthCustom);
    }
}

Getting started

Install packages

dotnet add package Typely.Core
dotnet add package Typely.Generators

Create a class inheriting from ITypelyConfiguration

public class TypesConfiguration : ITypelyConfiguration
{
    public void Configure(ITypelyBuilder builder)
    {
        builder.OfString().For("FirstName").NotEmpty();    
    }
}

Usage

var firstName = FirstName.From("Adam");
FirstName.From(""); //Throws ValidationException

if(!FirstName.TryFrom("value", out FirstName instance, out ValidationError? validationError))
{
    // Handle error
}
