Typely: Unleashing the power of value object creation with a fluent Api.

Example

public class TypesSpecification : ITypelySpecification { public void Create(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); } }

Documentation

• https://docs.typely.net/

Prerequisites

• Supported .NET versions

Getting started

Install packages

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

Create a class inheriting from ITypelySpecification

public class TypesSpecification : ITypelySpecification { public void Create(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 }
