Description

Mapperly is a .NET source generator for generating object mappings. Inspired by MapStruct.

Because Mapperly creates the mapping code at build time, there is minimal overhead at runtime. Even better, the generated code is perfectly readable, allowing you to verify the generated mapping code easily.

Programming language: C#

Quickstart

Installation

Add the NuGet Package to your project:

dotnet add package Riok.Mapperly

Create your first mapper

Create a mapper declaration as a partial class and apply the Riok.Mapperly.Abstractions.MapperAttribute attribute. Mapperly generates mapping method implementations for the defined mapping methods in the mapper.

// Mapper declaration
[Mapper]
public partial class CarMapper
{
    public partial CarDto CarToCarDto(Car car);
}

// Mapper usage
var mapper = new CarMapper();
var car = new Car { NumberOfSeats = 10, ... };
var dto = mapper.CarToCarDto(car);
dto.NumberOfSeats.Should().Be(10);
