Jupyter - Under the Hood

Dive deep into the inner workings of Jupyter Notebooks in this 40-minute conference talk from EuroPython 2022. Explore the distributed architecture of the Jupyter ecosystem, including the classic Jupyter Notebook, JupyterLab IDE, and JupyterHub. Discover how JSON documents form the core of Jupyter Notebooks, containing code, markdown styles, and outputs. Uncover the intricate processes behind running a notebook, from initiating a session with the notebook server to launching an IPython kernel and establishing communication between the Web UI, server, and kernel using REST APIs and ZMQ websockets. Examine the Jupyter Project's offerings and their scalable design, featuring front-end clients interacting with the Notebook server and language kernels. Gain hands-on experience by closely analyzing REST API calls and ZMQ socket traffic using browser tools, and learn to manipulate notebooks programmatically for a comprehensive understanding of Jupyter's internals.
