—Overview
What is class-transformer?
Class-Transformer is a TypeScript library that provides decorator-based serialization and deserialization of plain JavaScript objects into instances of classes. It simplifies the process of converting data structures, making it easier to work with complex object models in applications.
Key differentiator
“Class-Transformer stands out with its decorator-based approach, offering a more declarative way to handle object transformations compared to manual mapping or less flexible libraries.”
