Beginner Node.js routing upon on submit - node.js

Question

Just starting to play with node, and having a little bit trouble on routing, I looked on the routing separation example but thought it was a little bit advance for my skill, so I did in the following way, would anyone advice on the following code
index.html
<div class="container" id="test-container">
<h1>Test</h1>
<span id="test-error"></span>
<form id="test-input2">
<input type="text" id="test"></input>
</form>
</div>
ui.js
$('#test-input').submit(function(e){
e.preventDefault();
socket.emit('route', null);
});
ui_backend.js
exports.listen = function(server){
io = socketio.listen(server);
io.set('log level', 2);
io.sockets.on('connection', function(socket){
route_testing(socket);
});
}
function route_testing(socket){
socket.on('route', function(req, res){
res.render('test', function(err, html){
});
})
}
server.js
app.get('/test', function(req, res){
res.sendfile(__dirname + '/views/test.html');
});
Edit:
The problem is that I cannot get the routing to work.

Answer 1

Suggestion:
You setup a route in your server.js
app.get("/test", routes.page("test"));
In your ui_backend.js
module.exports = function (view) {
return function (req, res) {
res.render(view + ".html", {
page: view
});
};
};
Just do res.render() is fine. sendfile is not what you want.

Answer 2

function route_testing(socket){
socket.on('route', function(req, res){
res.render('test', function(err, html){
});
})
}
with socket.on(message,callback) , there is no req,res arguments. You are mixing up express and socket.io api.
on a socket message you need to emit another socket message. socket.emit(message)
socket.on('route', function(data){
socket.emit(message,somedata);
})
You basically have a server with 2 different protocols here, websockets and classic http.
The socket.io api is pretty clear: http://socket.io/ you cant make up a different api and expect it to work.
app.get('/test', function(req, res){
res.sendfile(__dirname + '/views/test.html');
});
sends /views/test.html as an attachement. You dont want to do that,you want express to render some html template or page:
app.get('/test', function(req, res){
res.render('test');
});
should work out of the box with a default express script.
So when you want to query over http, use the express api.
when you want to send message through websockets,use socket.io api.
