Downloads not working #79

Closed m-murphy closed 2 months ago

m-murphy commented 2 months ago

Hi,

I'm working on building a dashboard that would have some data download functionality, but it doesn't seem to work. The download file prompt opens, but the file sent is empty and named incorrectly. Here's a reproducible example

library(shiny)
library(bslib)

ui <- page_fluid(
    downloadButton("downloadData", "Download")
)

server <- function(input, output, session) {
    output$downloadData <- downloadHandler(
        filename = function() {
            paste("data-", Sys.Date(), ".csv", sep="")
        },
        content = function(file) {
            write.csv(mtcars, file)
        }
    )
}

shinyApp(ui = ui, server = server)

which is then exported using shinylive::export(".", "_static") and then hosted with httpuv::runStaticServer("_site")

Downloads work fine as a regular shiny app.

Here's my session info also if that helps
