The best practice for loading Pyodide involves using a CDN for simple, fast integration, utilizing Web Workers to keep the main thread responsive, and using for package management. As Pyodide constitutes a full Python interpreter load (~tens of MBs), performance optimization is critical. [1, 2, 3, 4, 5]
Here are the best practices for loading Pyodide:
- Initial Loading (CDN vs. Local)
• Use CDN for Development/Simplicity: The easiest method is to load directly from the jsDelivr CDN:
• Host Locally for Production: For better control, reliability, and offline capabilities, download the Pyodide files and serve them from your own web server.
• Asynchronous Initialization: Always load Pyodide asynchronously to prevent blocking the browser's main thread: [1, 2, 6, 7, 8]
- Performance & Threading
