SpereaMap

A lightweight, high-performance object-to-object mapper for .NET built on compiled expression trees.

Features

  • Convention-based mapping — matching property names automatically
  • Flattening — Customer.Email maps to CustomerEmail
  • Nested object mapping — child objects mapped recursively
  • Collection mapping — List<T>, arrays, IEnumerable<T>
  • ForMember / MapFrom — custom member configuration
  • Ignore / NullSubstitute — skip members or provide defaults
  • Conditions — PreCondition and post-resolution Condition
  • Value Resolvers — class-based resolution logic
  • Value Transformers — post-process values (e.g., trim strings)
  • BeforeMap / AfterMap — hooks with optional context
  • ResolutionContext — pass runtime parameters during mapping
  • Profiles — organize related mappings
  • ReverseMap — bidirectional mapping
  • ConvertUsing / ConstructUsing — full control over conversion
  • Validation — catch configuration errors early
  • Compiled expression trees — near-native performance

Quick Start

using SpereaMap.Core;

var config = new SpereaMapConfiguration(cfg =>
{
    cfg.CreateMap<Order, OrderDto>()
        .ForMember(d => d.FullName, o => o.MapFrom(s => s.Customer.FirstName + " " + s.Customer.LastName))
        .ForMember(d => d.Notes, o => o.Ignore());
});

config.AssertConfigurationIsValid();
var mapper = config.CreateMapper();

var dto = mapper.Map<Order, OrderDto>(order);

Passing Runtime Context

cfg.CreateMap<Order, OrderDto>()
    .AfterMap((src, dest, ctx) =>
    {
        dest.Total *= (1 - ctx.Get<decimal>("discount"));
    });

var dto = mapper.Map<Order, OrderDto>(order, ctx =>
{
    ctx.Items["discount"] = 0.10m;
});
