Live Chat: Implemented using Modulus and Node.js

In this tutorial, I will show you how to implement a real-time chat application using Node.js, Socket.IO, and MongoDB, and then we will deploy the application together to Modulus. First, let me show you the final look of the application that we will see at the end of the article. Node.js will be the core of the application, Express as the MVC, MongoDB as the database, and Socket. IO is used for real-time communication. Once completed, we will deploy the application to Modulus. The MongoDB part actually exists inside Modulus. 1.
