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:

Installation

Using conda:

$ conda install -c conda-forge ipyleaflet

Using pip:

$ pip install ipyleaflet
$ jupyter nbextension enable --py --sys-prefix ipyleaflet  # can be skipped for
notebook 5.3 and above

If you have JupyterLab, you will also need to install the JupyterLab extension:

$ jupyter labextension install jupyter-leaflet

Some users have found that the jupyterlab-manager is also required in jupyterlab if the map does not display.

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

Installation from sources

For a development installation (requires npm):

$ git clone https://github.com/jupyter-widgets/ipyleaflet.git
$ cd ipyleaflet
$ pip install -e .
$ jupyter nbextension install --py --symlink --sys-prefix ipyleaflet
$ jupyter nbextension enable --py --sys-prefix ipyleaflet
$ jupyter labextension install js  # If you are developing on JupyterLab

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.
