Input of Information into Javascript using terminal

Question

I want to take the output of a c++ program and input it into the stdin of a javascript file. However I have been unable to push anything into the stdin using the method...

Answer 1

This is how I process data from STDIN in Node:

function readStream(stream, callback) {
  var data = '';
  stream.setEncoding('utf-8');
  stream.on('data', onData);
  stream.on('end', onEnd);

  function onData(chunk) {
    data += chunk;
  }

  function onEnd() {
    stream.removeListener('end', onEnd);
    stream.removeListener('data', onData);
    callback(data);
  }
}

The error message in your questions (the "undefined is not a function") error means you were trying to call a method on stdin that doesn't exist. I couldn't find a mention of setRawMode in a cursory scan of the docs. Perhaps you are using an outdated API? I recall having to unpause STDIN (old-style streams) is deprecated.
