I feel I am pretty competent with Processing (java) but have no experience with servers and the like. What would be the best/easiest way to implement a “server/broker” that could allow multiple instances of a sketch simultaneously running in various locations around the country to have a synchronized high score list?

I know there are lots of way to accomplish this but the only one that I can think of would be to use the network library, link the client machines through a VPN like ZeroTierOne, and run a separate server sketch that can parse and compare the incoming scores. I have not tested it but it sounds doable. Thinking 100 clients max.  
Thanks!

I’m writing a drawing application in Processing and connect instances to a central server running a PHP/SQLite database using the contributed library, HTTP Requests for Processing. It’s pretty simple to send POST or GET (html form or query string style) data from Processing. PHP is what I chose but it could be Python, Perl, or even Java. Most web hosting platforms can handle a multitude of languages.

one solution: [Network / Libraries / Processing.org](https://processing.org/reference/libraries/net/index.html)

or my favorite  
node.js with express.js and [socket.io](http://socket.io)

Full example: [GitHub - iaido42/nodeTest\_p5Js: simple client/server with for p5js with node.js, express.js and socket.io](https://github.com/iaido42/nodeTest_p5Js.git)

[Socken.io](http://Socken.io) is a library and protocol based an WebSocket (only for the first connect) but is faster  
simple Server example server.js :  
var express = require(“express”);  
// express app instance  
var app = express();  
// server  
var server = app.listen(3000);  
// static files  
app.use(express.static(“public”));  
// [socket.io](http://socket.io) instance  
var socket = require(“[socket.io](http://socket.io)”);  
var io = socket(server);  
// new connection event  
io.sockets.on(“connection”, newConnection);  
function newConnection(socket) {  
console.log(“new connection” + socket.id);  
console.log(socket.id);  
// mouse event listener  
socket.on(“mouse”, mouseMsg);  
function mouseMsg(data) {  
// broadcast to all clients  
socket.broadcast.emit(“mouse”, data);  
console.log(data);  
}  
}

Install and first steps [Socket.IO](http://Socket.IO) with Node.Js + Express:

Client [Socket.io](http://Socket.io) Software for Java  
[GitHub - socketio/socket.io-client-java: Full-featured Socket.IO Client Library for Java, which is compatible with Socket.IO v1.0 and later.](https://github.com/socketio/socket.io-client-java)

very useful (p5js):
