Socket.io - Serving HTML
Socket.io with HTML
So far in index.js we’re calling res.send and pass it a HTML string. Our code would look very confusing if we just placed our entire application’s HTML there. Instead, we’re going to create a index.html file and serve it.
Let’s refactor our route handler to use sendFile instead:
app.get('/', function(req, res){
res.sendFile(__dirname + '/index.html');
});

And populate index.html with the following:
<!doctype html>
<html>
<head>
<title>Socket.IO chat</title>
<style>
* { margin: 0; padding: 0; box-sizing: border-box; }
body { font: 13px Helvetica, Arial; }
form { background: #000; padding: 3px; position: fixed; bottom: 0; width: 100%; }
form input { border: 0; padding: 10px; width: 90%; margin-right: .5%; }
form button { width: 9%; background: rgb(130, 224, 255); border: none; padding: 10px; }
#messages { list-style-type: none; margin: 0; padding: 0; }
#messages li { padding: 5px 10px; }
#messages li:nth-child(odd) { background: #eee; }
</style>
</head>
<body>
<ul id="messages"></ul>
<form action="">
<input id="m" autocomplete="off" /><button>Send</button>
</form>
</body>
</html>

If you restart the process (by hitting Control+C and running node index again) and refresh the page it should look like this:
