开发@L_874_13@

app.js

var http = require('http');
var fs = require('fs');

var server = http.createServer(function(req,res) {
    fs.readFile('./index.html','utf-8',function(error,content) {
        res.writeHead(200,{"Content-Type": "text/html"});
        res.end(content);
    });
});

var io = require('socket.io').listen(server);

io.sockets.on('connection',function (socket) {
    socket.on('newOrder',function () {
        socket.broadcast.emit('message','Nouvelle commande');
    });
});

server.listen(4321);

前端

<script src="{{ asset('http://localhost:4321/socket.io/socket.io.js') }}"></script>

<script>
    jQuery(function($) {
        var socket = io.connect('http://localhost:4321');

        $('form').on('submit',function() {
            socket.emit('newOrder','1');
        });

    });
</script>

后端

<script>
    jQuery(function($) {    
        var socket = io.connect('http://localhost:4321');

        socket.on('message',function(messagE) {
            alert(messagE);
        });
    });

</script>

启动服务器
