Flask-Marshmallow

Flask-Marshmallow is a thin integration layer for Flask, a Python web framework, and Marshmallow, an object serialization/deserialization library. It enhances Marshmallow with features like URL and Hyperlinks fields for HATEOAS-ready APIs and offers optional integration with Flask-SQLAlchemy. The current version is 1.4.0, and it follows a release cadence tied to Flask and Marshmallow updates.
