When you install jsii, you get the Python bindings and runtime machinery needed to call JavaScript classes as if they were native Python objects\u2014the framework handles marshalling, type conversion, and cross-language method dispatch behind the scenes.\n\nThe primary use case is consuming jsii-compiled libraries from Python code. Rather than rewriting libraries in every target language, teams author once in TypeScript, compile to jsii format, and jsii's language-specific runtimes (including this Python client) make those classes available with natural syntax in each language. It depends on attrs, cattrs, typeguard, publication, python-dateutil, and typing_extensions to handle serialization, type checking, and object lifecycle across the language boundary.","worth_installing":"Yes, if you are using jsii-compiled libraries in Python. The package is actively maintained, has no known vulnerabilities, installs with low friction, and carries a permissive Apache-2.0 license. Install only if you have a concrete need to consume jsii-compiled bindings; it is not useful as a standalone tool."},"id":"jsii","links":{"html":"https://skillfed.io/packages/jsii","md":"https://skillfed.io/packages/jsii.md","pypi":"https://pypi.org/project/jsii/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-07-17","license_spdx":null,"license_treatment":"permissive","name":"jsii","python_support":"supports_current","summary":"Python client for jsii runtime"},"popularity":{"monthly_downloads":9003259,"position":1569,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"1.139.0"}
