Rocket.Chat is an open source messaging app built with Meteor. It supports video conferencing, file sharing, voice messages, has a fully-featured API, and more. Rocket.Chat is great for those who prefer to have full control over their communications.

In this tutorial, we will be installing and configuring Rocket.Chat on a fresh Ubuntu Droplet as well as setting up a reverse proxy via Nginx to boost security and make accessing Rocket.Chat much easier. Once we're finished, you'll have a beautiful, functional instance of Rocket.Chat accessible from virtually anywhere.
