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

None of the above worked for me. I needed to use the Buffer object:

  const chunks = [];

  readStream.on("data", function (chunk) {
    chunks.push(chunk);
  });

  // Send the buffer or you can put it into a var
  readStream.on("end", function () {
    res.send(Buffer.concat(chunks));
  });
