Session
Pyodide is an open-source project that compiles CPython to WebAssembly, enabling native Python execution directly in browsers or Node.js. With built-in support for scientific libraries like NumPy and Pandas, it unlocks client-side computing potential for modern apps.
This talk shares practical use cases of Pyodide in frontend development—covering installation, DOM interaction, data analysis, and seamless JavaScript ↔️ Python communication. We'll explore how Pyodide empowers serverless, offline-first open source tools, and how it integrates Python into AI, and educational contexts.
