nodejs' request module doesn't give response in chunks

517 views Asked by At

I have one requirement to download the file from the server using nodejs.

Below is my code to download the file.

test.js

function downloadFile() {

    var fsModule = 'fs';
    var fs      = require(fsModule);
    var request = require('request');
    var deferred = $q.defer();

    var downloadRequest = request.get({
          encoding: null,
          url: 'https://test.com/api/assets/35007/raw',
          headers: {
              'Authorization': 'Basic AuthorizationValue'
          }
    });

    downloadRequest.addListener('response', function (response) {

        if (response.statusCode != 200)  {
            console.log('Error in downloading file');
            deferred.resolve(false);
        } else {
            var options = {defaultEncoding: 'binary'};
            var writeStream = fs.createWriteStream('c:/testDownloadFile.mp4', options);

            response.addListener('data', function (chunk) {
                console.log('chunk length - ',chunk.length);
                writeStream.write(chunk);
            });
            response.addListener("end", function() {
                writeStream.end();
                console.log('No error in download and resolved true');
                deferred.resolve(true);
            });
        }
    });
}
downloadFile();

I can run successfully this code using node by below command and it gives response in chunks. so there is no memory issue for this code.

node test.js

but when I run this code in browser using browserify then it doesn't give response in chunks. So it creates a problem for big size file.

  1. Is there any problem in browserify or request/buffer module?
  2. What should be the root cause for this issue?
  3. Could you please provide me the solution or alternate way to download the file in chunks?

Node Version: 6.9.2

browserify: ^12.0.0

Just a brief suggestion what what it's worth... In your testing environment did you have any modules held in cache that are not used in when testing in browser. I made this suggestion as there is no require for the q module.
