1) Create and activate a Python environment

python -m venv .venv
source .venv/bin/activate
python -m pip install --upgrade pip

2) Install Python and JS dependencies

pip install -e ".[dev]"
cd js
npm install
cd ..

3) Build widget frontend assets

cd js
npm run build
cd ..

For active development in one terminal:

cd js
npm run dev

4) Run marimo demo

In another terminal:

source .venv/bin/activate
marimo run marimo/demo.py

5) Smoke test

python scripts/smoke_widget.py

Packaging notes

• hatch-jupyter-builder runs the JS build during wheel/sdist builds.
• The static assets are included as shared data for notebook environments.

Build a package:

python -m pip install build
python -m build

Next customization points

• Add more synced traits in src/alignviz_anywidget/widget.py.
• Implement richer alignment rendering in js/src/index.js.
• Add additional marimo examples in marimo/.
