The idea is to add --profile to your shiny run command, and that will run Shiny under py-spy, then launch speedscope with the resulting trace.

TODO

  • On Windows, sys.orig_argv has two executables in the argv array (python.exe and shiny.exe), we just need the second. Why?
  • Currently pass the profiling data to speedscope.app via URL hash, need to work around the limits of URL hash sizes.
