How do I upload my existing R Shiny web app to my RStudio and Shiny Server?

  1. Verify that the R Studio and Shiny Server web app access is working, by visiting the Shiny site (see above “Connecting to the R Shiny Web App”). You should see the “Welcome to Shiny Server!” default Shiny demo app.

  2. Open RStudio Server (see above “Connecting via RStudio Server”).

  3. In the “Files” panel at the bottom right of RStudio, check that the current working folder is /srv/shiny-server. This is the default folder that Shiny uses to store web app files.
