ipyleaflet

A Jupyter / Leaflet bridge enabling interactive maps in the Jupyter notebook.

Usage

Selecting a basemap for a leaflet map:

Loading a geojson map:

Making use of leafletjs primitives:

Using the splitmap control:

Displaying velocity data on the top of a map:

Choropleth layer:

Widget control

Installation

Using conda:

conda install -c conda-forge ipyleaflet

Using pip:

pip install ipyleaflet

If you are using the classic Jupyter Notebook < 5.3 you need to run this extra command:

jupyter nbextension enable --py --sys-prefix ipyleaflet

If you are using JupyterLab, you will need to install the JupyterLab extension:

jupyter labextension install @jupyter-widgets/jupyterlab-manager jupyter-leaflet

Installation from sources

For a development installation (requires npm, you can install it with conda install -c conda-forge nodejs):

git clone https://github.com/jupyter-widgets/ipyleaflet.git
cd ipyleaflet
pip install -e .

If you are using the classic Jupyter Notebook you need to install the nbextension:

jupyter nbextension install --py --symlink --sys-prefix ipyleaflet
jupyter nbextension enable --py --sys-prefix ipyleaflet

If you are using JupyterLab, you need to install the labextension for ipywidgets and ipyleaflet:

jupyter labextension install @jupyter-widgets/jupyterlab-manager js

Note for developers:

the -e pip option allows one to modify the Python code in-place. Restart the kernel in order to see the changes.
the --symlink argument on Linux or OS X allows one to modify the JavaScript code in-place. This feature is not available with Windows.

For automatically building the JavaScript code every time there is a change, run the following command from the ipyleaflet/js/ directory:
```
npm run watch
```
If you are on JupyterLab you also need to run the following in a separate terminal:
```
jupyter lab --watch
```
Every time a JavaScript build has terminated you need to refresh the Notebook page in order to load the JavaScript code again.
