Goal: send radius value from maxmsp to p5js through [socket.io](http://socket.io)
Current State: testing with index.html works well, but when changed to p5js client, I can’t see the result or reaction.
[socket.io](http://socket.io) server part
```auto
const express = require('express');
const app = express();
const http = require('http').Server(app);
const io = require('socket.io')(http);
app.get('/', (req, res) => {
res.sendFile(__dirname + '/index.html');
})
//below use to solve the loading problem
app.use(express.static(__dirname + '/public'));
io.on('connection', (socket) => {
console.log('new connection >> '+ socket.id);
socket.on('disconnect',function(){
console.log('disconnected >> '+socket.id);
})
socket.on('message', (msg) => {
io.emit('message', msg);
})
socket.on('radius', (data) => {
io.emit('radius',data);
})
})
http.listen(3000, () => {
console.log('listening on *:3000');
})
```
maxmsp client part
```auto
const maxApi = require('max-api');
const io = require('socket.io-client');
let socket;
maxApi.addHandler('connect', (url) => {
socket = io(url);
});
maxApi.addHandler('disconnect', () => {
socket.close();
});
maxApi.addHandler('message', (msg) => {
socket.emit('message', msg);
});
```
index.html (works well and successfully console.log the value)
```auto

Looking at the code, there is no need for r and you shouldn’t have two set up functions, you should delete the second function setup.
This function should be like this;
function drawCircle(msg){
fill(255)
ellipse(width/2,height/2, msg)
}

To Chigoz
Thank you for conquering the blind spots.
I’ve edited the code and it is working normally.
Many thanks to you. This problem bothered me few days.
