Release 1.6.0

Breaking Changes

• Paginator output structure: The paginator now enforces a standardized structure:

  • Data is always placed under the data property (no longer configurable)
  • Metadata is now nested under the meta property instead of being merged at the top level

• Method renaming: Renamed serialize() methods to resolve() on Paginator, Item, and Collection classes to better reflect their purpose. These methods build return values using transformers and resolve relationships rather than performing serialization (which happens during HTTP response transmission).

• Automatic JSON serialization: Transformer return values are now recursively JSON serialized. This means data types like Date objects will be automatically converted to strings.

Features

• Additional transformer parameters: You can now pass additional parameters to transformers for greater flexibility.

• Type retention: Added support for retaining specific data types during type-level serialization via the ExtendedJSONTypes interface. For example, you can configure transformers to keep Date objects as Date instead of converting them to strings.

Improvements

• Performance optimization: Significantly improved performance of recursive type resolution, reducing type instantiations from ~20,000 to ~1,700.

• Build tooling: Migrated to tsdown for the build process.
