                        Production environments: relied on by real users with real consequences if they go wrong. Goals are uptime, security, correctness, responsiveness. #Rstudioconf

                      Can shiny be used in production? Yes, possible and now easy. Challenges are organizational, culural and technical. #Rstudioconf

                    Cultural: many app designers are users and don’t necessarily know best practices, performance and scale testing, security testing. #Rstudioconf

                  Organizational: IT/management are skeptical, credibility gap. Engineering department may be biased against R. #Rstudioconf

            shinyloadtest to see how fast apps are. Use profvis to improve R processes. Improve by moving work out of shiny, make code faster, caching, async. Recheck in shinyloadtest. #Rstudioconf

        How to improve? Use profvis to id bottlenecks in your app. Cranwhales spends too much time on loading in app. Load/process data ahead of time. Save as feather files for quick loading. Automate this using scheduling. #Rstudioconf

      Good candiates are slow plots, and plots that users frequently request. Add caching in renderPlot and tell shiny what input variables matter #rstudioconf
