**Streaming**
In order to keep this library lightweight, performant, and keep the code easy to
read, the streaming behavior is **_slightly different_** from that of
`request.js`.
```js
var request = require('@root/request');
var resp = await request({
url: 'http://www.google.com',
stream: true
});
resp.on('data', function () {
// got some data
});
resp.on('end', function () {
// the data has ended
});
// resp.stream is a Promise that is resolved when the read stream is destroyed
await resp.stream;
console.log('Done');
```
The difference is that we don't add an extra layer of stream abstraction.
You must use the response from await, a Promise, or the callback.
You can also give a file path:
```js
request({
url: 'http://www.google.com',
stream: '/tmp/google-index.html'
});
```
Which is equivalent to passing a write stream for the file:
```js
request({
url: 'http://www.google.com',
stream: fs.createWriteStream('/tmp/google-index.html')
});
```
