Jupyter kernels accessed via markdown forms in md lesson area

[psychemedia]

Putting this down as a marker for ways in which the markdown component of the lessons could be backed with interactive code executed using a pseudo-remote Jupyter kernel (by which I mean a kernel running in a container in the current users lab context; eg in a Jupyter server kernel launched via the lesson plan config) or where the md/html panel is being served more directly from a Jupyter server (I think scriptedforms serves HTML pages via a Jupyter server, erm maybe?)

This would allow Jupyter kernel backed code to be executed, and the code execution results displayed, from within the markdown scripted element of a lesson rather than a notebook.

There are several demonstrations in the wild of HTML based UIs fronting calls to remote Jupyter servers that process code in a Jupyer kernel environment and return results for display in the HTML page.

For example:

• DS100 textbook based on jupyter-book;
• spaCy course, which uses the juniper.js package to launch Jupyter kernels on MyBinder and interact with them from an arbitrary web page;
• scriptedforms which let you create md+webform UIs with code execution in a backend Jupyter kernel;
• thebelab which lets you edit and execute code in a remotely launched Jupyter kernel;
• voila, which executes "safe" (not arbitrary) code in a remotely launched Jupyter kernel (I think!)

This is all really cool! Thanks for sharing - this would definitely give authors some options for sharing their snippets.
