JavaScript console errors when running local shinylive export #83

Closed daattali closed 1 month ago

daattali commented 1 month ago

Using latest shiny 1.8.1.1 and shinylive 0.1.1, using the example from ?export:

app_dir <- system.file("examples", "01_hello", package = "shiny")
out_dir <- tempfile("shinylive-export")
export(app_dir, out_dir)
httpuv::runStaticServer(out_dir)

The JS console is full of errors:

Closing as a duplicate of posit-dev/shinylive#86, we'll track the issue there.

As mentioned in that thread, these are not really error messages and are related to how Shinylive is handling stderr message output from webR. It should indeed be changed, but for the moment you can safely ignore the preload error:Downloading webR package output lines.
