node.js - Easy HTTP requests with gzip/deflate compression

Question

I'm trying to figure out how the best way to easily send HTTP/HTTPS requests and to handle gzip/deflate compressed responses along with cookies.

The best I found was https://github.com/mikeal/request which handles everything except compression. Is there a module or method that will do everything I ask?

If not, can I combine request and zlib in some manner? I tried to combine zlib and http.ServerRequest, and it failed miserably.

Answer 1

For anyone coming across this in recent times, the request library supports gzip decompression out of the box now. Use as follows:

request(
    { method: 'GET'
    , uri: 'http://www.google.com'
    , gzip: true
    }
  , function (error, response, body) {
      // body is the decompressed response body
      console.log('server encoded the data as: ' + (response.headers['content-encoding'] || 'identity'))
      console.log('the decoded data is: ' + body)
    }
  )

From the github readme https://github.com/request/request

gzip - If true, add an Accept-Encoding header to request compressed content encodings from the server (if not already present) and decode supported content encodings in the response. Note: Automatic decoding of the response content is performed on the body data returned through request (both through the request stream and passed to the callback function) but is not performed on the response stream (available from the response event) which is the unmodified http.IncomingMessage object which may contain compressed data. See example below.
