A Python library providing a simple decorator-based API for serializing dataclasses to and from JSON. It supports nested dataclasses, collections, datetime objects, letter-case configuration, and optional schema validation.

Use cases

• serialize python dataclasses to
• decode into typed dataclasses
• convert camelCase to snake_case dataclass fields
• validate payloads against dataclass schemas
• handle nested dataclass serialization
• serialize datetime fields in dataclasses to

When to choose

• you use Python dataclasses and need easy JSON round-tripping
• you want typed decoding of JSON with minimal boilerplate
• you need letter-case mapping between Python fields and JSON keys
• you want optional schema validation on deserialization

When to avoid

• you need high-performance serialization for large datasets
• you prefer pydantic-style validation with rich constraints
• you need serialization formats other than JSON
