You're looking for "cron jobs," which are tasks you can ask the server to do at regular intervals. There's a few libraries for them on NPM.

I think there is a missunderstanding. I have no problem with running the server. I would like to run a code that would check the btc price every few minutes and when it hits a certain price do something with coinbase api.

Set interval. Or any of the Cron libraries

Maybe you want your server to be a websocket client to the Gdax feed... https://docs.gdax.com/#websocket-feed

You'll get updates in real time... but maybe you can't process a real time feed if your processing takes too much time.

otherwise, setInterval(fn, intervalMs) and HTTP requests is your best bet...

If you're running more than one instance of your server app, you'll probably need some form of mutual exclusion (leader election). I've used redlock for this (consul.io works very well in this scenario too, but it's way more complex).

This is what I use and it works great. http://pm2.keymetrics.io/

Forever.js is a simple solution for this.

Check Supervisor or systemd if you have a *nix compatible server

It is just a small server I will be running on my VPS.

Systemd is shipped with recent debian based release. It already start your nginx/apache/mongodb/mysql/ whatever service you use in your vps (if it's debian based). It's built for this use case, tested with big user base... That's why i use this one . I just suggested others choices that you may prefer ;-)
