ShinyProxy is a novel, open source platform to deploy Shiny apps for the enterprise or larger organizations. Since the last release (see this blog post), we received two interesting use cases for which we did not imagine ShinyProxy would be used.

First of all, we received a request to support other authentication methods than LDAP authentication. Whereas ShinyProxy is currently used primarily by larger organizations and companies that typically work with LDAP-based authentication systems, it seems people appreciate the elegance of the framework also for more small-scale use. In particular we received a request to support file-based authentication. Since all configuration of ShinyProxy was always dealt with in one single configuration file (the application.yml file), we decided to stick with this principle.

In order to make use of this novel functionality, you will need to specify the 'simple' authentication system as follows:

shiny:
  proxy:
    authentication: simple

and users (and groups for authorization) can now be specified as

shiny:
  proxy:
    users:
    - name: bert
      password: password
      groups: scientists
    - name: ernie
      password: password
      groups: mathematicians

Since there are now multiple systems to specify users and groups (for authorization), some configuration parameters were renamed to make these more generally applicable. When you specify your apps in the apps block e.g. the groups for authorization are no longer called ldap-groups but just groups. Similarly the specification of the admin groups, i.e. user groups that have access to the admin area for viewing and managing active sessions, have moved up in the YAML configuration from shiny.proxy.ldap to shiny.proxy.

If file-based authentication was the last feature on your mind for ShinyProxy, there is one nice side effect, though: you can now demonstrate ShinyProxy apps with authentication on a machine without internet connectivity (since there is no need any more to reach an LDAP server).

A second use case we worked on since last release relates to the usage of ShinyProxy as part of an architecture where Shiny applications are brought to end users inside web sites managed through content management systems (e.g. Drupal). Already early on (version 0.1.0) we had foreseen to disable authentication for this type of setup (authentication: none) where the CMS would handle authentication, but now there was a request to pass information from the CMS to the Shiny app. Shiny has a nice mechanism in place to pass arguments via URLs (see this article), and so we made sure ShinyProxy honored this mechanism in 0.7.5.

Documentation has been updated on the project homepage and as always community support on this new release is available on our support site.

We are already back to our keyboards to work on the next release, so keep the suggestions coming and have fun with ShinyProxy!

Our previous post on the how and why of ShinyProxy triggered a lot of encouraging reactions. Here's our favorite:

Indeed choosing for Docker opens a world of possibilities for ShinyProxy and making you no longer dependent on a particular version of R or shiny is only one of the advantages.

We also received a number of useful suggestions and decided to quickly release the new features and fixes as version 0.7.0. Here are the most important ones:

  • allow one user to open multiple applications as requested by this Github issue
  • optional display of logos for apps on the landing page using a new configuration field logo-url
  • fix spurious error message on Jetty ALPN support

Why is this needed?

There is currently no valid open source alternative that offers this functionality.

What does it offer?

  • authentication
  • authorization
  • securing traffic with TLS/SSL
  • usage statistics
  • scalability

This is free and open source, is there also a paying and proprietary version?

If we can paraphrase the Discourse guys:

There is only one version of ShinyProxy - the awesome open source version. There's no super secret special paid commercial version with better or more complete features. Because ShinyProxy is 100% open source, now and forever, it belongs to you as much as it belongs to us. That's how community works.

The knarrs of Open Analytics have left the port of Antwerp on their way to Denmark. What will our delegation bring to Aalborg besides our loyal sponsorship?

Earlier this week we published an article with an analysis of the Ubuntu Edge Indiegogo crowdfunding campaign, and the outlook was bleak. Donations had slowed to a crawl, and Canonical's \$32 million goal appeared to be little more than a pipe dream.

Yes, readers replied, donations had died off, but that's par the course for crowdfunding efforts.
