Making Shiny apps faster with caching

January 21, 2021

Shiny's 1.6 has a new function, bindCache(), which makes it easy to dramatically speed up reactive expressions and output rendering functions. This allows many applications to scale up to serve several times more users without an increase in server resources.

Note: Shiny 1.6.0 isn't yet on CRAN, but will be in the next few days. In the meantime, you can install it with:

remotes::install_github(""rstudio/shiny@rc-v1.6.0"")
