How do I ungzip (decompress) a NodeJS request's module gzip response body?

I couldn't get request to work either, so ended up using http instead.

var http = require("http"),
    zlib = require("zlib");

function getGzipped(url, callback) {
    // buffer to store the streamed decompression
    var buffer = [];

    http.get(url, function(res) {
        // pipe the response into the gunzip to decompress
        var gunzip = zlib.createGunzip();            
        res.pipe(gunzip);

        gunzip.on('data', function(data) {
            // decompression chunk ready, add it to the buffer
            buffer.push(data.toString())

        }).on("end", function() {
            // response and decompression complete, join the buffer and return
            callback(null, buffer.join("")); 

        }).on("error", function(e) {
            callback(e);
        })
    }).on('error', function(e) {
        callback(e)
    });
}

getGzipped(url, function(err, data) {
   console.log(data);
});

try adding encoding: null to the options you pass to request, this will avoid converting the downloaded body to a string and keep it in a binary buffer.

Like @Iftah said, set encoding: null.

Full example (less error handling):

request = require('request');
zlib = require('zlib');

request(url, {encoding: null}, function(err, response, body){
    if(response.headers['content-encoding'] == 'gzip'){
        zlib.gunzip(body, function(err, dezipped) {
            callback(dezipped.toString());
        });
    } else {
        callback(body);
    }
});
