isqanderm/data-mapper

This project is a high-performance TypeScript/JavaScript data mapper and validator designed for ultra-fast object transformations. It's aimed at developers working with REST APIs, databases, and form data who need efficient data transformation without the overhead of dependencies like `reflect-metadata`. The library uses modern TC39 Stage 3 decorators and JIT compilation to deliver up to 42.7x better performance than alternatives like class-transformer, while maintaining a clean, type-safe API and zero runtime dependencies.
