This repository contains a collection of extensions that add functionality to the Jupyter notebook. These extensions are mostly written in Javascript and will be loaded locally in your browser.
The IPython-contrib repository is maintained independently by a group of users and developers and not officially related to the IPython development team.
The maturity of the provided extensions varies, so please create an issue at the project's github repository if you encounter any problems.
For Jupyter version 4 or 5, use the master branch of the repository. Most nbextensions have been updated to work with both Jupyter 4.x and 5.x, but occasionally things get missed, or the Jupyter API changes in a minor version update, so if anything doesn't work as you'd expect/hope, please do check the issues, or open a new one as necessary!
This repo is pretty much all in the main master branch, although there remain vestigial branches for IPython notebook versions 2.x and 3.x.
Due to major differences between the Jupyter Notebook and JupyterLab, the extensions in this repository will not work in JupyterLab. You will find a list of alternative extensions for JupyterLab on jupyterlab-contrib.
Documentation for all maintained extensions can be found at jupyter-contrib-nbextensions.readthedocs.io
All extensions that are maintained and active
have at least a yaml file to allow them being configured using the
jupyter_nbextensions_configurator
server extension, which is installed as a dependency of this package.
Most also have a markdown readme file for documentation.
The jupyter_nbextensions_configurator server extension shows an nbextensions
tab on the main notebook dashboard (file tree page) from which you can see each
nbextension's markdown readme, and configure its options.
To view documentation without installing, you can check the list at
jupyter-contrib-nbextensions.readthedocs.io/en/latest/nbextensions.html,
or browse the nbextensions
directory to read markdown readmes on github at
github.com/ipython-contrib/jupyter_contrib_nbextensions/tree/master/src/jupyter_contrib_nbextensions/nbextensions.
Some extensions are not documented. We encourage you to add documentation for them.
To install the jupyter_contrib_nbextensions notebook extensions, three steps
are required. First, the Python pip package needs to be installed. Then, the
notebook extensions themselves need to be copied to the Jupyter data directory.
Finally, the installed notebook extensions can be enabled, either by using
built-in Jupyter commands, or more conveniently by using the
jupyter_nbextensions_configurator
server extension, which is installed as a dependency of this repo.
The Python package installation step is necessary to allow painless installation of the nbextensions together with additional items like nbconvert templates, pre-/postprocessors, and exporters.
All of the nbextensions in this repo are provided as parts of a python package,
which is installable in the usual manner using pip or the setup.py script.
To install the current version from PyPi, simply type
pip install jupyter_contrib_nbextensions
Alternatively, you can install directly from the current master branch of the repository
pip install https://github.com/ipython-contrib/jupyter_contrib_nbextensions/tarball/master
All the usual pip options apply, e.g. using pip's --upgrade flag to force an
upgrade, or -e for an editable install.
There are conda packages for the notebook extensions and the jupyter_nbextensions_configurator available from conda-forge. You can install both using
conda install -c conda-forge jupyter_contrib_nbextensions
This also automatically installs the Javascript and CSS files
(using jupyter contrib nbextension install --sys-prefix), therefore
the second installation step below can be skipped.
You can also install from a cloned repo, which can be useful for development. You can clone the repo using
git clone https://github.com/ipython-contrib/jupyter_contrib_nbextensions.git
Then perform an editable pip install using
pip install -e jupyter_contrib_nbextensions
This step copies the nbextensions' javascript and css files into the jupyter
server's search directory, and edits some jupyter config files.
A jupyter subcommand is provided for the purpose:
jupyter contrib nbextension install --user
The command does two things: installs nbextension files, and edits nbconvert
config files. The first part is essentially a wrapper around the
notebook-provided jupyter nbextension install, and copies relevant javascript
and css files to the appropriate jupyter data directory.
The second part edits the config files jupyter_nbconvert_config.jsonand
jupyter_notebook_config.json as noted below in the options.
The command can take most of the same options as the jupyter-provided versions,
including
--userto install into the user's home jupyter directories--systemto perform installation into system-wide jupyter directories--sys-prefixto install into python'ssys.prefix, useful for instance in virtual environments, such as with conda--symlinkto symlink the nbextensions rather than copying each file (recommended on non-Windows platforms).--debug, for more-verbose output
In addition, two further option flags are provided to perform either only the config-editing operations, or only the file-copy operations:
--only-filesto install nbextension files without editing any config files--only-configto edit the config files without copying/symlinking any nbextension files. This edits the following files in the applicable jupyter config directory:jupyter_nbconvert_config.jsonto use some of the classes provided in the python modulejupyter_contrib_nbextensions.nbconvert_supportjupyter_notebook_config.jsonto enable the serverextensionjupyter_nbextensions_configurator.
Finally, the --perform-running-check option flag is provided in order to
prevent the installation from proceeding if a notebook server appears to be
currently running
(by default, the install will still be performed, even if a notebook server
appears to be running).
An analogous uninstall command is also provided, to remove all of the
nbextension files from the jupyter directories.
To use an nbextension, you'll also need to enable it, which tells the notebook interface to load it. To do this, you can use a Jupyter subcommand:
jupyter nbextension enable <nbextension require path>
for example,
jupyter nbextension enable codefolding/main
To disable the extension again, use
jupyter nbextension disable <nbextension require path>
Alternatively, and more conveniently, you can use the
jupyter_nbextensions_configurator
server extension, which is installed as a dependency of this repo, and can be
used to enable and disable the individual nbextensions, as well as configure
their options. You can then open the nbextensions tab on the tree
(dashboard/file browser) notebook page to configure nbextensions.
You will have access there to a dashboard where extensions can be
enabled/disabled via checkboxes.
Additionally, a short documentation for each extension is displayed, and
configuration options are presented.
For complex or customized installation scenarios, please look at the documentation for installing notebook extensions, server extensions, nbconvert pre/postprocessors and templates on the Jupyter homepage. Most nbextensions here should work fine with JupyterHub (because JupyterHub spawns regular notebook servers for each individual user), but won't work with JupyterLab (because the Javascript framework of JupyterLab is different from the notebook's, and is still rapidly changing under active development).

Most of the nbextensions are stored in the repository each as a separate subdirectory of
src/jupyter_contrib_nbextensions/nbextensions.
Each notebook extension typically has its own directory named after the extension, containing:
thisextension/thisextension.js- javascript implementing the nbextensionthisextension/thisextension.yml- file describing the nbextension to thejupyter_nbextensions_configuratorserver extensionthisextension/thisextension.css- optional CSS file, which may be loaded by the javascriptthisextension/README.md- readme file describing the nbextension in markdown format
A few (jupyter_highlight_selected_word, jupyter_latex_envs), exist as separate packages on pypi, which are included as dependencies of this package.
