what is the nodejs code for this curl command - node.js

Question

I can successfully execute this curl command from a Unix shell script and I can see output in C:\Users\OutputFile.csv. What is the equivalent code in NodeJS
curl -k -v --user 'helloworld:hello_password'
--header 'Accept: application/vnd.myDMS-dms-api+json; version=1'
-X POST 'https://DMS.com:3001/download/csv'
--data header=true -o C:\Users\OutputFile.csv
I tried using the Online curl to nodeJS converter and it has generated the following NodeJs code:-
var request = require('request');
var headers = {
'Accept': 'application/vnd.myDMS-dms-api+json; version=1'
};
var options = {
url: 'https://DMS.com:3001/download/csv',
method: 'POST',
headers: headers,
auth: {
'user': 'helloworld',
'pass': 'hello_password'
}
};
function callback(error, response, body) {
if (!error && response.statusCode == 200) {
console.log(body);
}
}
request(options, callback);
However, when I run this NodeJS code it does not show any output. Also how can I get this output to C:\Users\OutputFile.csv

Maybe the response isn't return before the script is terminated. You would want the request to be asynchronous:
You can use request-promise
Here's an example
var rp = require('request-promise');
function someFunction() {
let options = {
url: `someURL`,
method: 'POST',
body: {
some: 'payload'
},
json: true
};
return rp(options);
}
This will await the response.

A simple version of your API parameters using request-promise:
var rp = require('request-promise');
function downloadFile() {
var options = {
uri: 'https://DMS.com:3001/download/csv',
method: 'POST',
auth: {
user: 'helloworld',
pass: 'hello_password',
sendImmediately: true
},
headers: {
Accept:'application/vnd.myDMS-dms-api+json; version=1'
},
form: {
'header': 'true'
}
};
rp(options)
.then(function (body) {
console.log('Downloaded body was %d long', repos.length);
})
.catch(function (err) {
console.log(err)
});
}
downloadFile()
