Node.js - npm start - "Unable to connect to the database: { SequelizeHostNotFoundError: getaddrinfo ENOTFOUND undefined undefined:5432

I cloned a github repository for a website and I am trying to run it locally on my computer using Node.js "npm start" except there is the error

I understand this is a problem with accessing the database but I would like to know how to bypass that so I can edit the .js, .html, .css files only but I want to see the changes on my locally ran server.

OR

How to access/find the database address and connect it with node.js.

I am hosting the website on Digital Ocean and have a droplet and full access.
