Parse output of spawned node.js child process line by line

Question

I have a PhantomJS/CasperJS script which I\'m running from within a node.js script using process.spawn(). Since CasperJS doesn\'t support require()

Answer 1

Try this:

cspr.stdout.setEncoding('utf8');
cspr.stdout.on('data', function(data) {
  var str = data.toString(), lines = str.split(/(\r?\n)/g);
  for (var i=0; i

Note that the "data" event might not necessarily break evenly between lines of output, so a single line might span multiple data events.
