I would recommend you get and use express, then you could do routes
something like this:
app.get('/', function (req, res) {
> res.sendfile(__dirname + '/public/index.html');
> });
>
What this means, is that anytime a request happens on the root route, the
server responds with the index.html located in *.*/public/. Assuming the
file exists.
Also I would recommend that you use firefox's built in "debugger" to
examine why what you're expecting to happen, isn't happening.
Anyway express is very useful and in my humble option well worth the 22M
space it takes up. You're also welcome to install whichever version you
like, but I personally install globally and the latest version 3 such as .
. .
$ npm install -g express@3
Also while you're at it you may wish to do some googling / reading on
M.E.A.N. An Acronym for MongoDB, Express, Angularjs, Node.js.
