Throughout the tutorial, we'll be learning how to create a real-time chat app with Angular 9, Socket.IO, and Node.js.
Socket.IO primarily uses the WebSocket protocol to enable real-time bidirectional communication.
WebSocket is the internet protocol that allows for full-duplex communication between a server and clients. The server may send data to a client without the client initiating a request.
Let's see how to create a simple chat server with socket.io and WebSockets.
These are the steps of our tutorial:
Step 1 -- Creating the Chat Server
Step 2 -- Initializing the Angular 9 Project
Step 3 -- Installing the Socket.IO Wrapper
Step 4 -- Importing SocketIoModule
Step 5 -- Creating an Angular Chat Service
Step 6 -- Creating the Chat UI
Step 7 -- Serving the Chat Front-End
