On: Voilà turns Jupyter notebooks to standalone web applications

This is huge - This basically allows your analysts and data scientists to have a company wide impact by productionizing your code.

Plotly dash tried to do this, but was a bit weird to use.

I've been using the Jupyter AppMode plugin for a few years, it has been very useful for internal tools. Voilà looks similar, with more sheen, it's going to enable true rapid SPA development.

Voila author here: a major difference with AppMode is that AppMode is merely hiding the notebook interface, but still allows for arbitrary code execution.

Voila is meant for producing secure web apps.

hi - its very interesting that you talk about security. what's the deployment story here ?

in fact, now that i think of it - can you generate an output folder with a Dockerfile ? so a mere docker build will produce a running docker compatible "build" folder ?

Also, can you have a mode where you hide the source code ? i just get the output data ? for world viewable dashboards.

There are some details about this in the blog post. - no execution request is sent by the front-end. - code is stripped out unless explicitely stated otherwise. For deployment, we are working on several scenarios around JupyterHub.

[sandGorgon → SylvainCorlay]

your blog post still displays the code. Not sure if that can be turned off as well.

Please consider the request for a Docker based output build in addition to whatever you do for jupyterhub

From the blog post:

> with --strip_sources=False, input cells will be included in the resulting web application (as read-only pygment snippets).

So the sources are presumably not there by default.

I still feel like R/Shiny is miles ahead here, but Voilà looks like a step in the right direction

Shiny is okay as a way to share simple analytical apps but it's syntax and performance are atrocious.
