Question

I’m generating a node.js script inside a Perl program, and I want to run that through node.js, as a JavaScript interpreter. How canO run the node in $script without writing it to disk and then calling node, afterwards capturing the output.

I’m using the system command, which I think is good for this purpose.

Answer 1

Use IPC::Run or IPC::Open3.

use strictures;
use IPC::Run qw(run);
use autodie qw(:all run);

my $in = '… JavaScript goes here …';
my $out;
run ['node'], \$in, \$out;
