Load testing Shiny
September 6, 2018
shinyloadtest (https://github.com/rstudio/shinyloadtest) and shinycannon (https://github.com/rstudio/shinycannon) are two new tools that work together to help you answer the question: how many users can my app support? I’ll demonstrate using shinyloadtest to produce a “recording” of an interaction with a Shiny app, and then I’ll show how to use shinycannon to “play back” that recording, generating load. Then I’ll bring the data produced by the load test back into R for analysis. Finally, I’ll interpret the results and discuss techniques for increasing the number of users a Shiny app can support.
