This makes the encoded output identical every time for the same input, which is essential for cryptographic signing, content hashing, and any system where reproducible serialization matters.\n\nThe package wraps either simplejson (by default on CPython) or the standard library json module (on PyPy) and adds a preserialisation hook system to handle custom types. It requires Python 3.7 or newer and has no external runtime dependencies, making it lightweight to integrate into existing projects.","worth_installing":"Yes. Canonicaljson solves a real problem\u2014deterministic JSON serialization\u2014that the standard library does not address. It has no dependencies, low install friction, active maintenance, a permissive license, and no known vulnerabilities. Install it if your application requires reproducible JSON encoding for signing, hashing, or comparison; skip it if you only need standard JSON serialization."},"id":"canonicaljson","links":{"html":"https://skillfed.io/packages/canonicaljson","md":"https://skillfed.io/packages/canonicaljson.md","pypi":"https://pypi.org/project/canonicaljson/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2023-03-15","license_spdx":null,"license_treatment":"permissive","name":"canonicaljson","python_support":"supports_current","summary":"Canonical JSON"},"popularity":{"monthly_downloads":272563,"position":8208,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"2.0.0"}
