Publishing WASM Wheels to PyPI for Use with Pyodide
Simon Willison's Weblog·7 hours ago·Tutorial
Pyodide 314.0 removes a long-standing distribution bottleneck by allowing WebAssembly-compiled Python wheels to be published directly to PyPI, so any package author can now distribute Pyodide-compatible packages without Pyodide team involvement. Previously, the team manually built and hosted over 300 packages. Simon Willison celebrated by publishing luau-wasm — a Lua-based scripting language compiled to WASM — using Codex with GPT-5.5 to automate the packaging workflow.
