nodejs socket receive data from one port and make available on another port

I have two devices. One devices send data to one socket port ie. 9000 and another devices connected to another port ie. 8000 and I want 2nd device receive same data that is received on port 9000 from first device.

I want to make a script using nodejs and socket io to receive data from one port like: 192.168.25.42:9000 and same received data should be available on different port 192.168.25.42:8000

any help appreciated.

You'll need to have 2 socket.io servers, one listening on port 9000 and the other one listening on port 8000.

When one server receives data, you emit that data to the other one.

const express = require("express");
const http = require('http');

const app8000 = express();
const app9000 = express();

const server8000 = http.Server(app8000);
const server9000 = http.Server(app9000);

const io8000 = require('socket.io')(server8000);
const io9000 = require('socket.io')(server9000);

server8000.listen(8000);
server9000.listen(9000);

// Server on port 8000

io8000.on('connection', socket => {
    socket.on('my-event', data => {
        //Push data to clients connected to server on port 9000
        io9000.emit("event-from-8000", "From 8000: " + data);
    });
});

// Server on port 9000

io9000.on('connection', socket => {
    socket.on('my-event', data => {
        //Push data to clients connected to server on port 8000
        io8000.emit("event-from-9000", "From 9000: " + data);
    });
});
