Updated May 9, 2026

For data scientists and data engineers, Jupyter Notebooks provide a powerful and flexible environment for exploring, visualizing, and analyzing data.

Installation

1. Install Jupyter: pip install jupyterlab - Installs Jupyter Notebook, a web-based interactive computing environment for data science and data engineering. You can user another UI such as Jupyter CLI or Jupyter Desktop.

2. Install Deno: curl -fsSL https://deno.land/install.sh | sh - Downloads and installs the Deno runtime required for TypeScript execution in Jupyter notebooks. Visit Deno for official documentation.

3. Install Deno Jupyter Kernel: deno jupyter --install - Sets up the Deno kernel for Jupyter, enabling TypeScript support within notebooks.

4. Activate Deno Jupyter Kernel: deno jupyter --unstable - Enables the Deno kernel for Jupyter notebook usage.

Usage

1. Run Jupyter Notebooks: jupyter-lab - Launches the Jupyter Notebook server in the current working directory, which allows you to create and run Jupyter notebooks.

2. Select Deno Kernel in Notebook: Choose the Deno kernel from your notebook's kernel selection menu. VSCode users may need to install the default Jupyter kernel extensions.
