How to securely share Shiny's rendered data via REST API ?

[AbhishekHP]

We could deploy App with URL etc etc.
But how can we just share the rendered data in Shiny securely via REST API ?

plumber/R at main · rstudio/plumber · GitHub (package)

library(shiny)
library(tidyverse)

ui <- fluidPage(
  DT::dataTableOutput("display")
)

server <- function(input, output, session) {

  output$display <- DT::renderDataTable({
    #browser()
    DT::datatable(mtcars,
                  options = list(pageLength = 7,scrollX = TRUE))
  })
  # How to send this data via REST API securely ?
}
shinyApp(ui, server)

I would go for plumber, since it's designed to setup an API. There's a chapter about security in the documentation as well.

You could share data between shiny and plumber via a database for example. Is that an option for you?

great, could you please share an example ?

No, I don't have an example of that, It's just an idea that could fit your request.
But in the documentation for plumber, you can find links how to connect to a database, that might give you a good start.
