Walkthrough guide to deploy nodejs and postgres app using EC2, nginx and RDS

Deploying nodejs on AWS

1. Create AWS EC2 instance

We would prefer to go with Ubuntu Server 16.04 LTS (HVM) [ami-0d03add87774b12c5] for backward compatibility for older applications. But one can choose any version as per thier preference

2. Install nvm and Nodejs using nvm
