Fetch eats a lot of RAM. How to fix?

Question

JavaScript

var humanize = require('humanize');
var request  = require('request');

function fetch(url, c) {
  request(url, function(err, resp, body) {
        if (err) {
            c(err);
            return;
        }
        c(err, resp, body)
    });
}
function callback(err, resp, body) {
    var memory = process.memoryUsage();
    console.log("Memory usage: " + humanize.filesize(memory.heapUsed) + " / " + humanize.filesize(memory.heapTotal));
    fetch('тут_url_запроса', callback)
}
function Number() {
    fetch('тут_url_запроса', callback);
}
setInterval(Number, 350)

Here is almost the entire code. After reading the forums and other sites with information, I did not find anything ..
Ps I found the launch parameters on Habré: node --nouse-idle-notification --expose-gc server.js
they do not help.
With each request, the RAM grows up to >100 and the process is killed automatically.
So how to get rid of such an increase in RAM? After all, ordinary html requests require hard RAM.

Answer 1

Your fetch calls the callback passed to it, and the callback calls fetch again, and so on in a circle.

Answer 2

You don't need those keys, and node --max_old_space_size=128 server.js
128 is megabytes. Without keys, a node usually takes up 1.5GB of memory
