I have expressJs application i am going to save image in PDF file Here is my code to save image in pdf file

exports.getPDF = function (req, res) {
  doc = new PDF();
  doc.pipe(fs.createWriteStream('./public/Competition.pdf'));  
    db.competitions.find({where: {id: req.params.competitionId}}).success(function(competition){

    //MY_URL_IS = http://d16dgegkincj5i.cloudfront.net/1_2_brandLogo_new_update_code-thumbnail.png

    var options = {
        host: 'http://d16dgegkincj5i.cloudfront.net',
        port: 80,
        path: '/1_2_brandLogo_new_update_code-thumbnail.png'
    }

    var request = http.get(options, function(res){
      var imagedata = ''
      res.setEncoding('binary')

      res.on('data', function(chunk){
        imagedata += chunk
      })

      res.on('end', function(){
        fs.writeFile('./public/Competition.pdf', imagedata, 'binary', function(err){

          console.log('File saved.')
        })
      })
    })
  }).error(function(error){
  });
};

The error:

Error: getaddrinfo ENOTFOUND

means that the url was not found.

Just removing the http:// from your host should do the job, like:

var options = {
    host: 'd16dgegkincj5i.cloudfront.net',
    port: 80,
    path: '/1_2_brandLogo_new_update_code-thumbnail.png'
}
