First of all, let’s install our socket.io on the client side. For that run npm, I socket. io-client-side. It will install socket.io. Then we will import io from a socket. io-client, In a variable name socket, call the io function and then give your API link. It will connect to that server and give a used socket which will help us to make requests and send data through it.

On the server side install express and add all configuring express apps. Then install socket.io. After that solve cross-policy. Now we need to import Sever from socket.io and create io from that Sever with HTTP value. Then io. on(‘connection’) will provide a callback function which will give our socket. Now we can do socket.on method in the socket

io. After that solve cross-policy. Now we need to import Sever from socket.io and create io from that Sever with HTTP value. Then io. on(‘connection’) will provide a callback function which will give our socket. Now we can do socket.on method in the socket. On socket. on function the first value will be a string like a message then a call back function which will give data if anyone Emit data on message. After that, we have sent data back to all connected users with our server.

After that, we will add a socket.broadcast.emit(‘receive massage’). It will send our message data to all connected users but will have to add a socket. on(‘receive massage’) and pass callback function where we will add.
