Installation

pip install deckgl-marimo
# or
uv add deckgl-marimo

Requires Python 3.11+.

Extras

Extra	Installs	When you need it
`deckgl-marimo[binary]`	numpy	Binary data transport (`use_binary=True`, `pack_binary`)
`deckgl-marimo[marimo]`	marimo	`Map.as_widget()` outside an existing marimo environment

Inside a marimo notebook, marimo is already present — the extra exists for completeness. The core install is deliberately small (anywidget, traitlets, narwhals); bring whichever DataFrame library you already use.

Installing from source

Building from a git checkout or sdist compiles the JS bundle at install time and requires Node.js 20+:

git clone https://github.com/kihaji/deckgl-marimo
cd deckgl-marimo
uv pip install .

Prebuilt wheels from PyPI never need Node. See CONTRIBUTING for the development setup.
