If you need to download a file in NodeJS without using any third party libraries, then you can do the following.
The NodeJS ecosystem comes with a fs module, this is to denote the FileSystem built in library.
First declare your imports:
const http = require('https');
const fs = require('fs');
Now you can use the https module to download a file, and write it to a stream using fs.
const https = require("https");
const fs = require("fs");
const endpoint = "https://example/files/some_csv_file";
https.get(endpoint, (res) => {
const file_name = "the_csv.csv";
const writeStream = fs.createWriteStream(file_name);
});
