- [Instructor] Socket.io enables real time,…bidirectional, event based communication.…Express on the other hand allows the client…to send a request to the server,…but the server cannot send request to the client…and so it does not have bidirectional communication.…Socket.io solves this.…In other words, we can push notifications…from the server to the client…when an event happens, as well as other data.…We will see how this works eventually with our demo app.…Socket.io has two parts, a client side library…that runs on the browser,…and a server side library for node.js.…
Both components have an API that's nearly identical.…And just like node.js, it is event driven.…Now that we've had a brief intro…into some of the most popular web frameworks for node,…let's go ahead and create the demo application…utilizing them.…Let's look at that next.…
