Simon Willison runs Python ASGI apps in browser with Pyodide

By PulseAugur Editorial · [1 sources] ·

Simon Willison has successfully integrated Python ASGI applications into the browser using Pyodide and Service Workers. This new approach allows JavaScript within script tags to execute, overcoming a limitation of his previous Web Worker implementation for Datasette Lite. The breakthrough was achieved with assistance from Claude Opus 4.8, enabling demos of both a basic ASGI FastCGI setup and Datasette 1.0a31 running entirely in the browser. AI

IMPACT Enables more complex Python applications to run directly in the browser, potentially improving web development workflows.
