Getting started with Socket.io: Adding Real Time Events to your Node.js Express App

### Getting started with Socket.io: Adding Real Time Events to your Node.js Express App Socket.io is a websocket library for adding bi-directional, event-based communication between your server and client. This allows us to receive and emit events in real time whenever our data changes. To get started with socket.io, we need to have Node.js and npm installed, as well as create a Twilio account and purchase a phone number with Voice capabilities. We then set up the Express server by cloning a GitHub repository and installing Socket.io using npm. The code is then written to connect to Socket.io on the client side and log events that are received from the server. Finally, we modify the call status events route to emit an event with Socket.io whenever we receive an update from Twilio, allowing us to display real-time updates of phone calls in our dashboard app.
