It is a drop-in replacement for the archived quickjs package, so existing code using `import quickjs` continues to work unchanged.\n\nThe package provides a Context object for isolated JavaScript execution, a Function helper for thread-safe calls from multiple threads, and resource controls (memory limits, CPU time limits, stack size). Each Context owns its own QuickJS runtime with no shared state; threading is handled either by creating one Context per thread or by using the Function wrapper, which manages a dedicated worker thread internally. Pre-built wheels are available for Linux, Windows, and macOS across CPython 3.10+ and PyPy 3.10/3.11.","worth_installing":"Yes, with conditions. The package is actively maintained, has no known vulnerabilities, and offers a clean API for JavaScript embedding. However, verify the actual license text before use in proprietary projects, since metadata shows 'unclear' despite the description mentioning MIT. Install friction is medium due to the C extension, but pre-built wheels cover common platforms. Suitable for sandboxed script execution, prototyping, and projects that need lightweight JavaScript evaluation without a full Node.js runtime."},"id":"quickjs-ng","links":{"html":"https://skillfed.io/packages/quickjs-ng","md":"https://skillfed.io/packages/quickjs-ng.md","pypi":"https://pypi.org/project/quickjs-ng/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-08-01","license_spdx":null,"license_treatment":"unclear","name":"quickjs-ng","python_support":"supports_current","summary":"Thin Python wrapper of quickjs-ng"},"popularity":{"monthly_downloads":128737,"position":11696,"tier":"top_15000"},"security":{"n_vulnerabilities":0},"version":"0.16.0.1"}
