Jupyter Kernel for Deno

Deno ships with a built-in Jupyter kernel that allows you to write JavaScript and TypeScript; use Web and Deno APIs and import npm packages straight in your interactive notebooks.

Currently all code executed in the Jupyter kernel runs with --allow-all flag. This is a temporary limitation and will be addressed in the future.

You can run deno jupyter --unstable --install to force installation of the kernel. Deno assumes that jupyter command is available in your PATH.

After completing the installation process, the Deno kernel will be available in the notebook creation dialog in JupyterLab and the classic notebook:

Deno.jupyter namespaces provides helper function for displaying rich content in your notebooks using MIME types that Jupyter supports.

This is a regular function, so you you can use any library you want to format the output - eg. use @std/fmt/colors to provide a colorful output:

Deno.jupyter.broadcast allows to publish messages to the IO pub channel allowing to provide live updates as the cell is evaluated.
