How do you pipe a long string to /dev/stdin via child_process.spawn() in Node.js?

Question

I\'m trying to execute Inkscape by passing data via stdin. Inkscape only supports this via /dev/stdin. Basically, I\'m trying to do something like this

Answer 1

So, I figured out a work around. This seems like a bit of a hack, but it works just fine.

First, I made this one line shell script:

cat | inkscape -z -f /dev/stdin -A /dev/stdout | cat

Then, I simply spawn that file and write to the stdin like this:

cmd = spawn("shell_script");

cmd.stdin.write(svg);
cmd.stdin.end();
cmd.stdout.pipe(pipe);

I really think this should work without the shell script, but it won't (for me at least). This may be a Node.js bug.
