yamamotok/dataobject

Decorator-based utility for transformation (serialization/deserialization) between plain object and class instance, developed for TypeScript projects. An alternative to class-validator and class-transformer.

dataobject's Issues

Validator should be applied in process of transformation

Currently validation is applied before transformation, however I think it should be applied in process of transformation.

• undefined should be ignored and no need to apply validation (currently validation is before undefined check)
• It should be after custom transformer because usually a custom transformer has its own validation and type conversion.

Type coercion before validation for primitive types

While "dataobject" has implicit type coercion for primitive types (string, number, and boolean), a validator function to be set looks like this.

(value: unknown) => isLength(String(value), { max: 100 })

I think it would be nice if the type coerced value is passed to validation function.

(value: string) => isLength(value, { max: 100 })

v1.1.0

v1.1.0 will be released in a couple of weeks.
