This template provides the Pyodide kernel (jupyterlite-pyodide-kernel), the JavaScript kernel (jupyterlite-javascript-kernel), and the p5 kernel (jupyterlite-p5-kernel), along with other optional utilities and extensions to make the JupyterLite experience more enjoyable. See the requirements.txt file for a list of all the dependencies provided.

Rebuilding Pyodide and packages from pyodide-recipes

To rebuild a full Pyodide runtime plus all packages from the latest pyodide-recipes:

1. Ensure you have conda and rustup (rustup must be on PATH).
2. From the repo root, run:

   pyodide/build_world_from_recipes.sh

   This will:
   • create or update a pyodide-env conda environment based on pyodide-recipes/environment.yml
   • clone or update pyodide-recipes (by default into _pyodide-recipes/)
   • use pyodide build-recipes to build all recipes and generate a pyodide-lock.json
   • copy the resulting runtime, lock file, and wheels into this repo’s pyodide/ directory
3. Rebuild the site:

   ./build.sh

Environment variables:

• PYODIDE_RECIPES_DIR – where to clone pyodide-recipes (default: _pyodide-recipes under the repo root).
• PYODIDE_ENV_NAME – conda env name (default: pyodide-env).
• PYODIDE_RECIPES_TARGETS – package selection string for pyodide build-recipes (default: "*" for all packages; e.g. *,!imgui-bundle to disable a problematic recipe).
