I already have tried setInterval(), it seemed perfect but the issue is that it does not initiate the first call immediately and waits for X seconds and then it gives desired value, is there some other way or should I run it an infinite loop and put a sleep like functionality in it?

3Does this answer your question? Execute the setInterval function without delay the first timelusc– lusc2021-12-30 07:41:54 +00:00Commented Dec 30, 2021 at 7:41

You should try cronjob npmjs.com/package/node-crondivyraj– divyraj2021-12-30 07:47:26 +00:00Commented Dec 30, 2021 at 7:47

If your issue is simply it doesn't call for first time then it is OK
function doThis(){
console.log("hello");
}
const time = 1000;
doThis(); // Calls for the first time
setInterval(doThis(),time); // Now it starts the samething.
//There is another option also for same thing:
setInterval(function doThis() {
console.log('hello');
return doThis();
}(), time);
But It is not recommended if function takes longer than delayed time
More on this statement:

https://chrisblackwell.me/setinterval-is-bad/
function doThis() {
console.log("hellow");
setTimeout(doThis, 1500);
}
doThis();
The problem that happens with setInterval doesn't happen here, because this only schedules the next iteration, not all future ones.
For setInterval
For setTimeout

If the first line in func() is the settimeout call for the next iteration, won't they be identical or close-to?
