Wuphf

What is it?

Wuphf is a realtime chat application using Nodejs exploiting the Socket.IO library. It is a project to explore the power of Sockets and how they are used to broadcast data let alone send data to a particular entity!

How does it work?

The two main parts of the application are the server.js, main.js which are wound tightly to make the chat come alive!

Basics

A socket is an entity that can do two things (mainly):

1. Emit

   socket.emit("listener", { msg:'wuphf' });

2. Listen

   socket.on("listener", ({msg}) => {console.log(msg)});

3. BroadCast- Emits to everyone except user

   socket.broadcast.to(user.room).emit("message",);

4. BroadCast- To all members of the room including self

   io.to(user.room).emit('roomUsers',{room:user.room})

Step-up

Following are the lifecycle of a user entering the chat wrt sockets

• User joins room
• Welcome user and show the chatroom with list of all other users
• All users will be shown this user joined
• If user types, typing... will be shown
• As the user hits enter on the message , the socket registers the message and displays
• User leaves the chat , broadcast to all members that user left.
