It lets you define schemas declaratively\u2014specifying types, validators, and transformations\u2014then use them to validate incoming data and convert outgoing data to a serializable form.\n\nThe package is designed for web frameworks and APIs where you need to validate user input (form data, JSON payloads) and ensure it matches an expected structure before processing. It handles type coercion, custom validation logic, nested structures, and error reporting. With only two runtime dependencies and support for Python 3.7 and later, it integrates easily into most projects.","worth_installing":"Yes. Colander is a mature, actively maintained library with low install friction, no known vulnerabilities, and a permissive license. It solves a common problem\u2014validating and serializing structured data\u2014with a clean, extensible API. Install it if you need schema-based validation and serialization in a web framework or data-processing pipeline."},"id":"colander","links":{"html":"https://skillfed.io/packages/colander","md":"https://skillfed.io/packages/colander.md","pypi":"https://pypi.org/project/colander/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2023-01-03","license_spdx":null,"license_treatment":"permissive","name":"colander","python_support":"supports_current","summary":"A simple schema-based serialization and deserialization library"},"popularity":{"monthly_downloads":240223,"position":8907,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0"}
