isn't this jquery? =/
Not at all.
node.js
lets you use Javascript on your server. The article talks about
using node.js to create a server to accept web socket connections
and talk to your MySQL server.
Do
you want to use Javascript on your server? If so, node.js is a nifty
solution! Otherwise, pick a server language or framework, and do
some searches to see how you can deal with websockets in that language/framework.
In
any case, you need to write server code to deal with the other end
of the websocket. We can't help you with that here. We can point
you in a direction.
For
the client side, modern browsers have a websocket API built-in. If
your target browser doesn't have one, you are out of luck. There
might be some libraries that add something that the built-in API
doesn't have, or that normalizes differences between browsers.
Jake might be able to offer some advice, since he's played a lot
with websockets.
In
any case, jQuery has nothing to offer.
