Including binary files results in error

[jfunction]

Simple app.R (note I saved an rds file but could be a 1x1 pixel png or any binary file):

library(shiny)

# saveRDS(1,"one.rds")

ui <- fluidPage(
  titlePanel("Hello Shiny!"),
  sidebarLayout(
    sidebarPanel(
      sliderInput("bins",
                  "Number of bins:",
                  min = 1,
                  max = 50,
                  value = 30)
    ),
    mainPanel(
      plotOutput("distPlot")
    )
  )
)

server <- function(input, output, session) {
  output$distPlot <- renderPlot({
    x    <- faithful$waiting
    bins <- seq(min(x), max(x), length.out = input$bins + 1)
    hist(x, breaks = bins, col = 'darkgray', border = 'white')
  })
}

shinyApp(ui, server)

Good news! I think this error has been fixed in the latest version of shinylive (the web assets). We're planning on releasing the R package to CRAN soon, which will use the latest shinylive assets. In the mean time, you can try using the development version of shinylive, which you can install with

pak::pak("posit-dev/r-shinylive")

With the CRAN version of r-shinylive, I see

shinylive::assets_info()
#> shinylive R package version:  0.1.1
#> shinylive web assets version: 0.2.3

and the latest dev version of r-shinylive

shinylive::assets_info()
#> shinylive R package version: 0.1.1.9000
#> shinylive web assets version: 0.3.0
