Correct use of Unirest.pipe

[cosmicflame]

Hi, it's me again!

Quick question for you - I noticed that Unirest.pipe is defined as an alias to Unirest.request.pipe:
https://github.com/Mashape/unirest-nodejs/blob/master/index.js#L703
Unirest.pipe = Unirest.request.pipe;
This does not appear to documented in the readme.

I'm trying to download images using Unirest and have stumbled across a method that seems to work:

var unirest = require('unirest')
var fs = require('fs')

unirest.get("https://www.google.co.uk/logos/doodles/2014/dorothy-hodgkins-104th-birthday-born-1910-5134139112030208.3-hp.jpg")
  .end()
  .pipe(fs.createWriteStream(__dirname + '/myImg.jpg'))

Is this how Unirest.pipe is intended to be used, chained after .end(), or am I doing it wrong?

Thanks.

This is a little tricky, pipe won't work on .end too much sugar going on there. This has to do with something I've been wanting to change around, but it will make things a little different going forward.

.end() does the whole shebang and instead I would rather return a request instance the whole way along instead. True aliasing.

It does actually work and save the file though... Presumably this is a matter of "might work sometimes, but not supported" as it were, then?

[nijikokun]

Ah, it will work because it is returned:

https://github.com/Mashape/unirest-nodejs/blob/master/index.js#L489

However, it's not as pure as request.get().pipe(); would be.

[cosmicflame]

So... a-ok correct usage of Pipe for writing files? :)

[nijikokun]

File manipulation is easier using request directly right now in my opinion.

The Unirest API is much nicer, though ;)
I'm trying to get an app I'm working on down to using a single HTTP client library. If I'm reading your responses correctly (which is to say that it will work, but this is an area where Unirest will improve in the future) then mission accomplished! :)

[nijikokun]

Alright, closing this then :)

Thanks for the help, and thanks most of all for unirest-nodejs - this library is making my job a whole lot easier and nicer! :D
