# CHANGELOG
## v1.8.0
- add `resp.ok` - same as WHATWG fetch `resp.ok = (resp.statusCode >= 200 && resp.statusCode < 300)`
- add `resp.stream.body()` to populate `resp.body` rather than (or perhaps in addition to) continuing to stream (useful for error handling)

# Extra
There are some niche features of @root/request which are beyond the request.js
compatibility.
## async/await & Promises
The differences in async support are explained in [README.md](/README.md), up near the top.
If you're familiar with Promises (and async/await), then it's pretty self-explanatory.
## ok
Just like WHATWG `fetch`, we have `resp.ok`:
```js
let resp = await request({
url: 'https://example.com'
}).then(mustOk);
```
```js
function mustOk(resp) {
if (!resp.ok) {
// handle error
throw new Error('BAD RESPONSE');
}
return resp;
}
```
## streams
The differences in stream support are explained in [README.md](/README.md), up near the top.
## userAgent
There's a default User-Agent string describing the version of @root/request, node.js, and the OS.
Add to the default User-Agent
```js
request({
// ...
userAgent: 'my-package/1.0' // add to agent
});
```
Replace the default User-Agent
```js
request({
// ...
headers: { 'User-Agent': 'replace/0.0' }
});
```
Disable the default User-Agent:
```js
request({
// ...
headers: { 'User-Agent': false }
});
```

µRequest is designed to be a drop-in replacement for request. It supports HTTPS and follows redirects by default. @root/request is designed to be a drop-in replacement for request. It also supports Promises and async/await by default, enhanced stream support, and a few other things as mentioned below.

**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`.
```diff
-var request = require('request');
+var request = require('@root/request');
-var stream = request({ url, headers });
+var stream = await request({ url, headers });
let attachment = await new MailgunAPI.Attachment({
data: stream
})
```
Example:
```js
var request = require('@root/request');
var resp = await request({
url: 'http://www.google.com',
stream: true // true | 'filename.ext' | stream.Writable
});
// 'resp' itself is a ReadableStream
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; // returns `undefined`
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')
});
```
Also, `await resp.stream.body()` can be used to get back the full body (the same as if you didn't use the `stream` option:
```js
let resp = await request({
url: 'http://www.google.com',
stream: true
});
if (!resp.ok) {
await resp.stream.body();
console.error(resp.body);
}
```

The following are features that the original `request` did not have, but have been added for convenience in `@root/request`.
- Support for `async`/`await` & `Promise`s (as explained above)
- `request({ userAgent: 'my-api/1.1' })` (for building API clients)
- `resp.ok` (just like `fetch`)
- `resp.stream` (see above)
