Python API and Jupyter widget facilitating interactive visualization of spatial single-cell data with Vitessce.

To install with pip:

$ pip install vitessce

Explore our example notebooks. These contain demos of different use cases and integrations with single-cell data analysis packages.

For a development installation (requires NodeJS and NPM),

$ git clone https://github.com/vitessce/vitessce-python.git
$ cd vitessce-python
$ conda env create -f environment.yml
$ conda activate vitessce-jupyter-dev
$ pip install -e .
$ jupyter nbextension install --py --symlink --overwrite --sys-prefix vitessce
$ jupyter nbextension enable --py --sys-prefix vitessce

When actively developing your extension for JupyterLab, run the command:

$ jupyter labextension develop --overwrite vitessce

Then you need to rebuild the JS when you make a code change:

$ cd js
$ npm run build

You then need to refresh the JupyterLab page when your javascript changes.

In this repository, there are multiple conda environments for different purposes:

• vitessce-jupyter-dev (defined in environment.yml) is used for the development of the vitessce package itself
• vitessce-jupyter-examples (defined in docs/notebooks/environment.yml) is used for running the example notebooks in the docs/notebooks/ directory (see docs/notebooks/README.md for more information)
• vitessce-jupyter-binder (defined in binder/environment.yml) is the environment used by Binder upon opening notebooks from this repository

cd tests
python -m unittest

make html

To deploy a new version, increment the version of the Python package in vitessce/_version.py and the JS package in js/package.json:

cd js
npm version patch

Then, when you push or merge the code with the incremented versions to master, the GitHub Action deploy.yml workflow will build and push the packages to PyPI and NPM.
