shinylive 0.3.0.9000 not using sf::sf_use_s2(FALSE)

[p-schaefer]

shinylive 0.3.0 allows use of the sf package despite lack of s2 on r-wasm by setting sf::sf_use_s2(FALSE):

However, shinylive 0.3.0.900, the result is:

I have tried shinylive::export(..., assets_version ="0.10.6") and shinylive::export(..., assets_version ="0.9.3") with the same result. I would really like to use shinylive 0.3.0.900 because I also want to use jsonvalidate with V8, which is not available/working in shinylive 0.3.0.

Below is an example app demonstrating the issue:

library(shiny)
library(mapview)
library(munsell)
sf::sf_use_s2(FALSE)

if (F){
  wd<-tempdir()
  unlink(file.path(wd,"docs"),recursive=T)
  # shinylive::export(wd, file.path(wd,"docs"), assets_version ="0.10.6")
}

ui <- fluidPage(
  leaflet::leafletOutput("test"),
)

server <- function(input, output) {

  output$test <- leaflet::renderLeaflet({
    mapview::mapview()@map
  })

}

# Create Shiny app ----
shinyApp(ui = ui, server = server)
