nteract is first and foremost a dynamic tool to give you flexibility when writing code, exploring data, and authoring text to share insights about the data.

Edit code, write prose, and visualize.

We support Jupyter kernels locally on your system and on remote JupyterHubs via Binder.


Installing the nteract desktop application

If you're here to install the nteract desktop app, visit nteract.io to download a binary and install or visit the releases page. The nteract desktop app ships with a NodeJS kernel by default. If you'd like to use other Jupyter kernels, you will need to install them.

Installing nteract web

Our current flavor of nteract web runs on top of the Jupyter server. Install it with pip:

pip install nteract_on_jupyter
jupyter serverextension enable nteract_on_jupyter

Now, run jupyter nteract and you're running nteract on the Jupyter web application!

Try the nteract playground

The nteract playground is a web-based application that allows you to write code and execute code in a web-based editor supported by Binder and Jupyter kernels. You can learn more about in the nteract play GitHub repo.

Overview of nteract's monorepo

This repository is a monorepo, which basically means that the repository hosts more than one module or application. In our case, we have two main directories:

packages/ -- components used as an individual library
applications/ -- all the user facing applications (i.e. desktop)

The packages directory has the components needed to build new applications, and the applications has the desktop app and the Jupyter extension.

Why have a monorepo? The monorepo contains many components and packages that can be mixed and remixed to create new applications. The monorepo keeps these elements together so they are easy to discover and use. Another benefit is that the monorepo makes it easy to iterate on applications that share common components. For example, if we update a component, such as the Jupyter message handling, and happen to introduce an issue when making a change to the desktop app, we would notice the issue in tandem.

Getting Started

To get started developing, set up the nteract monorepo.

Set the monorepo up in dev mode

Requires Node.js and yarn.

  1. Fork this repo
  2. Clone your fork or this repo git clone https://github.com/nteract/nteract
  3. cd to the directory where you cloned it
  4. yarn install

To keep up-to-date with changes to the root nteract/nteract branch:

  1. Set the root as a remote: git remote add upstream https://github.com/nteract/nteract.git

When changes are made to the root nteract/nteract, they can then be pulled from the root and merged to your master branch:

  1. git pull upstream master
  2. yarn clean
  3. yarn install

Building a specific package

In some cases you'll want to modify an individual base package (i.e. commutable or transforms) and not rebuild all of the other packages. To target a build of a specific package, use this command, replacing packageName with the fully qualified name of the package you want to hack on:

yarn build:only packageName

For example, to hack on the transforms package, use

yarn build:only @nteract/transforms

Hacking on the Desktop application

Quick and dirty (manual)

yarn app:desktop

As you make changes, you will have to close the entire app (CMD-q on macOS or CNTL-c at the terminal) and then run yarn app:desktop again to see the changes.

Progressive Webpack build (automatic)

In separate terminals run:

yarn build:desktop:watch


yarn spawn

This progressive webpack build will keep rebuilding as you modify the source code. When you open a new notebook, you'll get the fresh, up-to-date copy of the notebook app.


console.log statements in the main Electron process are piped to stdout. console.log statements in the Electron renderer process go to the regular Dev Tools console (accessible from the View menu). Set ELECTRON_ENABLE_LOGGING=1 to pipe renderer console.log to the launching terminal as well. This is useful for debugging crashes and notebook closing behaviors.


I upgraded my developer installation and things are broken!

  • Try yarn clean && yarn

I want to debug redux actions and state changes.

  • Enable redux-logger by spawning the application with yarn spawn:debug.

I keep getting a pop-up asking: Do you want the application "nteract Helper.app" to accept incoming network connections? while developing or using a custom build of nteract on macOS.

  • This is how the the macOS firewall behaves for unsigned apps. On a signed app, the dialog won't show up again after approving it the first time. If you're using a custom build of nteract, run:

    sudo codesign --force --deep --sign - /Applications/nteract.app

    You will have to do this again every time you rebuild the app.
