I am excited to announce the redesign and reorganization of shiny.rstudio.com, also known as the Shiny Dev Center. The Shiny Dev Center is the place to go to learn about all things Shiny and to keep up to date with it as it evolves. The goal of this refresh is to provide a clear learning path for those who are just starting off with developing Shiny apps as well as to make advanced Shiny topics easily accessible to those building large and complex apps.

Shiny 1.0.4 is now available on CRAN. To install it, run: install.packages("shiny") For most Shiny users, the most exciting news is that file inputs now support dragging and dropping: It is now possible to add and remove tabs from a tabPanel, with the new functions insertTab(), appendTab(), prependTab(), and removeTab(). It is also possible to hide and show tabs with hideTab() and showTab(). Shiny also has a new a function, onStop(), which registers a callback function that will execute when the application exits.

Shinydashboard 0.6.0 is now on CRAN! This release of shinydashboard was aimed at both fixing bugs and also bringing the package up to speed with users’ requests and Shiny itself (especially fully bringing bookmarkable state to shinydashboard’s sidebar). In addition to bug fixes and new features, we also added a new “Behavior” section to the shinydashboard website to explain this release’s two biggest new features, and also to provide users with more material about shinydashboard-specific behavior.

Shiny 1.0.1 is now available on CRAN! This release primarily includes bug fixes and minor new features. The most notable additions in this version of Shiny are the introduction of the reactiveVal() function (like reactiveValues(), but it only stores a single value), and that the choices of radioButtons() and checkboxGroupInput() can now contain HTML content instead of just plain text. We’ve also added compatibility for the development version of ggplot2. Read more →

Shiny Server 1.5.1.834 and Shiny Server Pro 1.5.1.760 are now available. The Shiny Server 1.5.x release family upgrades our underlying Node.js engine from 0.10.47 to 6.9.1. The impetus for this change was not stability or performance, but because the 0.10.x release family has reached the end of its life. We highly recommend that you test on a staging server before upgrading production Shiny Server 1.4.x machines to 1.5. You should always do this for any production-critical software, but it’s particularly important for this release, due to the magnitude of changes to Node. Read more →

Shiny Server 1.4.7.815 and Shiny Server Pro 1.4.7.736 are now available! This release includes new features to support Shiny 0.14. It also updates our Node.js to 0.10.47, which includes important security fixes for SSL/TLS. Connection robustness (a.k.a. grey-outs) Shiny’s architecture is built on top of websockets, which are long-lived network connections between the browser and an R session on the server. If this connection is broken for any reason, the browser is no longer able to communicate with its R session on the server. Read more →

If there’s one word that could describe the default styling of Shiny applications, it might be “minimalist.” Shiny’s UI components are built using the Bootstrap web framework, and unless the appearance is customized, the application will be mostly white and light gray. Fortunately, it’s easy to add a bit of flavor to your Shiny application, with the shinythemes package. We’ve just released version 1.1.1 of shinythemes, which includes many new themes from bootswatch. Read more →

We’ve just released Shiny Server and Shiny Server Pro 1.4.6. Relative to 1.4.2, our previously blogged-about version, the 1.4.6 release primarily includes bug fixes, and mitigations for low-severity security issues found by penetration testing. The full list of changes is after the jump. If you’re running a Shiny Server Pro release that is older than 1.4.3 and are configured to use SSL/TLS, it’s especially important that you upgrade, as the versions of Node. Read more →
