import { classes } from './classes';

class B {

const listeners = new Set<(message: string) => void>;

const server = Bun.serve({

    async fetch(req, srv){
        if(req.method === 'OPTIONS') {
            return new Response('', {
                headers: {
                    'Access-Control-Allow-Origin': '*',
                    'Access-Control-Allow-Methods': 'GET, OPTIONS',
