Uncompress gzip response body in Node.js with zlib example

dezip.js

var request = require('request')
var zlib = require('zlib')

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

Request can handle it out of the box

  var request = require('request')
  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)
    }
  )

Thank you so much.
