jupyterhub-fancy-profiles

A react based, fancy implementation of user selectable profiles for use with jupyterhub-kubespawner.

Features

  1. Interpret a profileList given to kubespawner, and render a better looking and more featureful selector. This includes descriptions for various options, as well as better descriptions for allowing users to 'write-in' a choice.

  2. If enabled, interact with a binderhub deployed as a JupyterHub service to allow users to dynamically build images they want to use, without requiring it to be pre-built.

Limitations

  1. While multiple profile_options are supported, only a single profile is supported.

  2. The forms values don't remember their previous state upon refresh

How to use

Once installed, you can have kubespawner use the templates shipped with this package to provide appropriate UI, by adding the following snippet to your jupyterhub_config.py file:

from jupyterhub_fancy_profiles import setup_ui
setup_ui(c)

The setup_ui function will setup all the appropriate config as needed. Currently, it will:

  1. Setup extra templates to be made available to kubespawner, to render the base HTML for profile_list.
  2. Setup extra HTTP handlers, primarily for serving our static assets.

What is in here?

The primary contents are:

  1. jupyterhub_fancy_profiles/templates contains jinja2 templates, primarily HTML for constructing the form itself. This can contain multiple templates that are composed together using all of jinja2's composition features (like include)
  2. src/ contains JS and CSS that are packaged via standard frontend bundling tools (webpack and babel), outputing assets into jupyterhub_fancy_profiles/static/. This allows us to use standard frontend tooling to write JS & CSS - for example, xterm.js can be used without many complications.

Why React?

/* If this file gets over 200 lines of code long (not counting docs / comments), start using a framework

(from the BinderHub JS Source Code)

Dear Reader, the file did get more than 200 lines long, but alas there was no time to start using a framework. Lesson learnt from that is we should use a very lightweight framework right from the start, something mainstream that can attract frontend devs without being so fancy that nobody else can work on it. Given the size and complexity of this - a complex UI but only a single page - plain react without typescript seems the correct choice. We will not make this into a super-heavy, complex application - just a fairly simple one that uses react.
