A convention based object to object mapper using [Roslyn source generator](https://github.com/dotnet/roslyn/blob/master/docs/features/source-generators.md).
MapTo is a library to programmatically generate the necessary code to map one object to another during compile-time, eliminating the need to use reflection to map objects and make it much faster in runtime. It provides compile-time safety checks and ease of use by leveraging extension methods.

## Installation ## Installation

dotnet add package MapTo --prerelease dotnet add package MapTo --prerelease
``` ```
## Usage ## Usage
MapTo relies on a set of attributes to instruct it on how to generate the mappings. To start, declare the destination class as `partial` and annotate it with `MapFrom` attribute. As its name implies, `MapFrom` attribute tells the library what the source class you want to map from is. MapTo relies on a set of attributes to instruct it on how to generate the mappings. To start, declare the destination class as `partial` and annotate it with `MapFrom` attribute. As its name implies, `MapFrom` attribute tells the library what the source class you want to map from is.
```c# ```c#
using MapTo; using MapTo;
namespace App.ViewModels namespace App.ViewModels
{ {
[MapFrom(typeof(App.Data.Models.User))] [MapFrom(typeof(App.Data.Models.User))]
public partial class UserViewModel public partial class UserViewModel
{ {
public string FirstName { get; } public string FirstName { get; }
public string LastName { get; } public string LastName { get; }
[IgnoreProperty] [IgnoreProperty]
public string FullName { get; set; } public string FullName { get; set; }
} }
} }
``` ```
To get an instance of `UserViewModel` from the `User` class, you can use any of the following methods: To get an instance of `UserViewModel` from the `User` class, you can use any of the following methods:
```c# ```c#
var user = new User(id: 10) { FirstName = "John", LastName = "Doe" }; var user = new User(id: 10) { FirstName = "John", LastName = "Doe" };
var vm = user.ToUserViewModel(); // A generated extension method for User class. var vm = user.ToUserViewModel(); // A generated extension method for User class.
// OR // OR
vm = new UserViewModel(user); // A generated contructor. vm = new UserViewModel(user); // A generated contructor.
// OR // OR
vm = UserViewModel.From(user); // A generated factory method. vm = UserViewModel.From(user); // A generated factory method.
``` ```

## Available Attributes ## Available Attributes
### IgnoreProperty ### IgnoreProperty
By default, MapTo will include all properties with the same name (case-sensitive), whether read-only or not, in the mapping unless annotating them with the `IgnoreProperty` attribute. By default, MapTo will include all properties with the same name (case-sensitive), whether read-only or not, in the mapping unless annotating them with the `IgnoreProperty` attribute.
```c# ```c#
[IgnoreProperty] [IgnoreProperty]
public string FullName { get; set; } public string FullName { get; set; }
``` ```
### MapProperty ### MapProperty
This attribute gives you more control over the way the annotated property should get mapped. For instance, if the annotated property should use a property in the source class with a different name. This attribute gives you more control over the way the annotated property should get mapped. For instance, if the annotated property should use a property in the source class with a different name.
```c# ```c#
[MapProperty(SourcePropertyName = "Id")] [MapProperty(SourcePropertyName = "Id")]
public int Key { get; set; } public int Key { get; set; }
``` ```
### MapTypeConverter ### MapTypeConverter
A compilation error gets raised by default if the source and destination properties types are not implicitly convertible, but to convert the incompatible source type to the desired destination type, `MapTypeConverter` can be used. A compilation error gets raised by default if the source and destination properties types are not implicitly convertible, but to convert the incompatible source type to the desired destination type, `MapTypeConverter` can be used.
This attribute will accept a type that implements `ITypeConverter<in TSource, out TDestination>` interface. This attribute will accept a type that implements `ITypeConverter<in TSource, out TDestination>` interface.
