NodeJS require concept for local modules

The problem

As your NodeJS app grows bigger, the file structure tends to go 3 to even 5 layers deep. The problem now is as you require local modules you created, you'll have to write them in this way:

const myModule = require('../../../my/module');

Node.js Deployment

Steps to deploy a Node.js app to DigitalOcean using PM2, NGINX as a reverse proxy and an SSL from LetsEncrypt

1. Sign up for Digital Ocean

If you use the referal link below, you get $10 free (1 or 2 months) https://m.do.co/c/5424d440c63a

2. Create a droplet and log in via ssh

I will be using the root user, but would suggest creating a new user
