What is the best way to download a big file in NodeJS?

The below server code is working fine for 5GB file using wget http://localhost:11146/base/bigFile.zip but not using client side code.

Server side code.

var http = require("http");
var fs = require("fs");
var filename = "base/bigFile.zip";

var serv = http.createServer(function (req, res) {
    var stat = fs.statSync(filename);
    res.writeHeader(200, {"Content-Length": stat.size});
    var fReadStream = fs.createReadStream(filename);
    fReadStream.on('data', function (chunk) {
       if(!res.write(chunk)){
           fReadStream.pause();
       }
   });
   fReadStream.on('end', function () {
      res.end();
   });
   res.on("drain", function () {
      fReadStream.resume();
   });
});

serv.listen(1114);

Client side code using Request module. What is wrong in this code?

var request = require('request')
request('http:/localhost:11146/base/bigFile.zip', function (error, response, body) {
  console.log('error:', error); // Print the error if one occurred
  console.log('statusCode:', response && response.statusCode); // Print the response status code if a response was received
  console.log('body:', body); // Print the HTML for the Google homepage.
});

error for above client side code is below -

error: Error: Invalid protocol
    at Request.init (/Users/air/Projects/node_modules/request/request.js:338:51)
    at new Request (/Users/air/Projects//node_modules/request/request.js:105:8)
    at request (/Users/air/Projects/Vertico/Vertico-CLI/node_modules/request/index.js:53:11)
    at Object.<anonymous> (/Users/air/Projects/req.js:2:1)

    at Function.Module._load (module.js:458:3)
    at Function.Module.runMain (module.js:605:10)
statusCode: undefined
body: undefined

I revised client side to use wget shell process instead of request package, that code is below, the problem is - I am not able to see nice download progress of wget, any work around for this code, such that I can see the progress bar in child process.

const fs = require('fs');
   const child_process = require('child_process');

   var workerProcess = child_process.spawn('wget', ['-O','fdsf.zip', 'http://localhost:11146/base/bigFile.zip']);

   workerProcess.stdout.on('data', function (data) {
     console.log('stdout: ' + data);
   });

   workerProcess.stderr.on('data', function (data) {
     //console.log('stderr: ' + data);
   });

   workerProcess.on('close', function (code) {
      console.log('Download Completed' + code);
   });

So finally I want to know how to download a file using client side code written in nodejs?
