Got: How to get the response body from a stream?

[PierBover]

What would you like to discuss?

How do we get the response.body when using got.stream ?

got.stream.put(options).on('response', (response) => {
  console.log(response.body); // returns undefined
});

This is a Node.js basic question. Google "how to read a readable stream in Node.js"

I finally got it:

const body = [];

got.stream.put(options)
.on('end', () => {
    console.log(Buffer.concat(body).toString());
})
.on('data', (chunk) => {
    body.push(chunk);
});

You could use https://github.com/sindresorhus/get-stream to simplify that.

Thanks @sindresorhus it was easier than I thought.

I was just confused by the response event. :P

The response gives the raw response, and in 99% you don't need it unless you want to modify its properties.
