I want to target nodejs for a little command line tool (which accompanies other JS stuff).

Is there any way to read the command line parameters under the JS backend? I tried the standard paramCount() and paramStr() from the os module, but get a run time exception "paramCount is not implemented on Nintendo Switch".

BTW, this happens with and without -d:nodejs.

You could checkout Nodejs Nim which may have what you need, have not checked myself though.

I would support a well written PR that adds paramCount, paramStr to -d:nodejs (see also https://github.com/nim-lang/Nim/pull/15826)

While I'm usually against JS specific code in "native Nim", in this case I encourage such a PR too.

Thanks @ElegantBeef. Will give it a try.

Would be better to keep platform specific code away from Nim's core.
1. Node is not only platform, there's also Deno which could be the future.
2. Even in Node.JS many essential functions are not in the core but in libraries.
So the libraries to deal with Node.JS (or Deno) feels better. Like import node/fs or import deno/fs.
