{"library":"pyodide","type":"library","category":null,"description":"Pyodide is an open-source project that compiles the CPython interpreter to WebAssembly, enabling the full execution of Python directly within web browsers and Node.js environments without requiring a server backend. Its current stable release is 0.29.3, with frequent patch and minor updates; a significant version change to 314.0.0a1 signals alignment with upcoming Python 3.14 releases and a revised ABI stabilization strategy. Key differentiators include seamless bidirectional interoperability between JavaScript and Python, comprehensive support for a vast array of popular scientific Python libraries (such as NumPy, Pandas, and Matplotlib), and a lightweight package manager (`micropip`) that allows dynamic installation of pure Python wheels from PyPI. This enables advanced client-side data processing, interactive visualizations, and powerful educational tools to run entirely within the browser, significantly expanding Python's reach in web development.","language":"javascript","status":"active","version":"0.29.3","tags":["javascript","python","webassembly","typescript"],"install":[{"cmd":"npm install pyodide","imports":["import { loadPyodide } from 'pyodide';\n// Or for older Node.js/CJS:\n// const { loadPyodide } = require('pyodide');","import type { PyodideInterface } from 'pyodide';","await pyodide.runPython(`\n  import sys\n  print('Hello from Python!', file=sys.stderr)\n`);","await pyodide.loadPackage('numpy');","await pyodide.loadPackage('micropip');\nconst micropip = pyodide.pyimport('micropip');\nawait micropip.install('matplotlib');"]},{"cmd":"yarn add pyodide","imports":[]},{"cmd":"pnpm add pyodide","imports":[]}],"homepage":"https://pyodide.org","github":"https://github.com/pyodide/pyodide","docs":null,"changelog":null,"pypi":null,"npm":"https://www.npmjs.com/package/pyodide","openapi_spec":null,"status_page":null,"smithery":null,"compatibility":{"summary":{"python_range":"18–22","success_rate":0,"avg_install_s":null,"avg_import_s":null,"wheel_type":null},"url":"https://checklist.day/v1/registry/pyodide/compatibility"},"provenance":{"verified_status":null,"verified_at":null,"last_verified":"Wed Jun 17","next_check":"Sat Jul 18","install_tag":null}}
