const http = require("http");
const Koa = require("koa");
const KSR = require("koa-static-resolver");
const socketIO = require("socket.io");

const open = require("open");

const app = new Koa();
app.use(KSR({
    dirs: [
        "./test/client/",
        //for livereload
        "./node_modules/socket.io-client/dist/",

const server = http.createServer(app.callback());
const io = socketIO(server);
io.on("connection", function(client) {
    client.on("data", function(data) {
    });
    client.on("disconnect", function() {
        console.log(`${new Date().toString()} a preview page disconnected`);
    });
    console.log(`${new Date().toString()} a preview page connected`);
});

const sockets = io.sockets;

const port = 8080;
server.listen(port, function() {
    const url = `http://localhost:${port}`;
    console.log(`${new Date().toString()} server started: ${url}`);
    open(url);
