(This answer is from years ago, when it was the best answer. There is now a better answer below this. I haven't kept up with node.js, and I cannot delete this answer because it is marked "correct on this question". If you are thinking of down clicking, what do you want me to do?)
The key is to use the `data` and `end` events of a Readable Stream. Listen to these events:
stream.on('data', (chunk) => { ... });
stream.on('end', () => { ... });
When you receive the `data` event, add the new chunk of data to a Buffer created to collect the data.
When you receive the `end` event, convert the completed Buffer into a string, if necessary. Then do what you need to do with it.
