Node.js One-Click Application

DigitalOcean’s One-Click application installs Node.js for a lightweight and efficient platform for building fast, scalable network applications. Similar in design to Ruby’s Event Machine or Python’s Twisted, and built on Chrome’s JavaScript runtime, it’s a great fit for data-intensive apps that run across distributed devices.

Components

Component Version
Linux Ubuntu 18.04.1
Node.js Latest from APT
NPM Latest from APT

In addition to the package installation, the One-Click also:

  • Enables the UFW firewall to allow only SSH (port 22, rate limited), HTTP (port 80), and HTTPS (port 443) access.

Quickstart

After you create a Node.js One-Click Droplet, Node.js and NPM will both be installed. This One-Click application is ideal for learning and exploring with Node.js, but isn’t configured for production use. For example, some steps you should take before using Node.js One-Click Droplets in production include:

  • Using PM2, a process manager for Node.js that lets you daemonize applications so they can run in the background as a service.

  • Using a reverse proxy, like Nginx, to give users a way to access the application.

  • Adding SSL to the reverse proxy for additional security.

  • If your application supports it, using multiple Droplets to add redundancy.

The guide How To Set Up a Node.js Application for Production on Ubuntu 18.04 explains these steps and more, like using the NodeSource PPA to get the latest LTS releases of Node.js.

If you’re not building a production app, you can use the built-in development server to begin learning Node.js. For the example in the linked Node.js documentation, make sure to open port 3000, as this One-Click’s UFW configuration doesn’t allow that port by default:

ufw allow 3000
