Deploy node.js in production

Question

What are the best practices for deploying a nodejs application in production?

I would like to know how deploy for production Api\'s nodejs is being done

Answer 1

I can only add from experience on AWS using a NAT Gateway which is a dedicated Node server with a MongoDB server behind the gateway. (Obviously this is a scalable system and project.)

1. With or without Docker, you need to control the production environment. This means clearly defining which NPM libraries you will need for production, how you handle environment variables and clusters for cores.

2. I would suggest, very strongly, using a tool like PM2 to handle clusters, server shutdowns and restarts and logs. (Workers & slaves also if you need them and code for them).

This list can go on and on, but keep in mind this is only from an AWS perspective. Setting up a Gateway correctly on AWS is also not an easy process. Be prepared for some gotcha's along the way.
