GitHub releases#
You can also download Pyodide packages from GitHub
releases
(the pyodide-build-*.tar.bz2
file).
You will need to serve these files yourself.
Serving Pyodide packages#
Serving locally#
With Python 3.7.5+ you can serve Pyodide files locally with http.server
:
python -m http.server
from the Pyodide distribution folder. Navigate to http://localhost:8000/console.html and the Pyodide repl should load.
Remote deployments#
Any service that hosts static files and that correctly sets the WASM MIME type and CORS headers will work. For instance, you can use GitHub Pages or similar services.
For additional suggestions for optimizing the size and load time for Pyodide, see the Emscripten documentation about deployments.
