How to Implement a Data Helper for Microservices in Python

import json
from dataclasses import dataclass, asdict
from typing import Any, Dict, List


@dataclass
class ServiceResponse:
    status: str
    data: Any
    message: str = ""


class DataHelper:
    """Simple helper for microservice data handling."""

    @staticmethod
    def serialize(data: Dict[str, Any]) -> str:
        return json.dumps(data)

    @staticmethod
    def deserialize(data: str) -> Dict[str, Any]:
        return json.loads(data)

    @staticmethod
    def wrapper_response(data: Any, status: str = "success") -> ServiceResponse:
        return ServiceResponse(status=status, data=data)


if __name__ == "__main__":
    payload = {"user_id": 42, "name": "Alice", "roles": ["admin"]}
    serialized = DataHelper.serialize(payload)
    print("Serialized:", serialized)

    deserialized = DataHelper.deserialize(serialized)
    print("Deserialized:", deserialized)

    response = DataHelper.wrapper_response(deserialized)
    print("Response:", asdict(response))
