This tutorial will show you how to create a simple, yet functional video chatroom using the OpenTok API and Sinatra. Sinatra is a Ruby framework which allows you to quickly create web apps.
The app we’ll be creating will be a simple website which will allow you to instantly create a video chatroom.
So, let’s get started! First of all, you’ll need to install Sinatra. To do this, type the following command in the terminal:
