How To Set Up a Node.js Application for Production on Ubuntu 16.04


Node.js is an open source JavaScript runtime environment for easily building server-side and networking applications. The platform runs on Linux, OS X, FreeBSD, and Windows. Node.js applications can be run at the command line, but we’ll focus on running them as a service, so that they will automatically restart on reboot or failure, and can safely be used in a production environment.

In this tutorial, we will cover setting up a production-ready Node.js environment on a single Ubuntu 16.04 server. This server will run a Node.js application managed by PM2, and provide users with secure access to the application through an Nginx reverse proxy. The Nginx server will offer HTTPS, using a free certificate provided by Let’s Encrypt.
