The plan
- Repository
- s-knibbs/dataclasses-jsonschema
- Base commit
- b5ccd44 (image tag)
- Issue
- Add to_json and from_json convenience methods It'd be nice to add `from_json` and `to_json` methods for convenience
- Files to edit
dataclasses_jsonschema/__init__.py
- Approach
- add two new classmethods - from_json(json_str, *, encoding="utf-8", validate=True, skip_invalid=False) returning instance created via from_dict(json.loads(...)), and to_json(*, indent=None, ensure_ascii=True, validate=False) returning string of dump(to_dict()) after handling parameters; they must delegate to existing from_dict/to_dict respectively so nothing in core functionality changes beyond providing thin wrappers around stdlib json module imports already allowed elsewhere in file.

- Finish summary
- Added `from_json` and `to_json` convenience methods to the JsonSchemaMixin class in dataclasses_jsonschema/__init__.py. The `from_json` classmethod parses a JSON string and creates an instance using the existing `from_dict` method, with options for encoding, validation, and skipping invalid fields. The `to_json` instance method serializes the dataclass instance to a JSON string using the existing `to_dict` method, with options for indentation, ASCII encoding, and validation. Both methods properly delegate to the existing core functionality, maintaining backward compatibility while providing convenient JSON serialization/deserialization capabilities.
