How do I read the contents of a Node.js stream into a string variable?

Question

I\'m hacking on a Node program that uses smtp-protocol to capture SMTP emails and act on the mail data. The library provides the mail data as a stream, and I don\'t know how

From the nodejs documentation you should do this - always remember a string without knowing the encoding is just a bunch of bytes:

var readable = getReadableStreamSomehow();
readable.setEncoding('utf8');
readable.on('data', function(chunk) {
  assert.equal(typeof chunk, 'string');
  console.log('got %d characters of string data', chunk.length);
})
