10 years ago I think socket.io would be appropriate since it's probably faster than constantly asking for changes via ajax. Also as far as I know socket.io downgrades to ajax if websockets are not available. Something like this would be a good start:
I also started implementing a Websocket server for this library. You can take a look at it, too. It's located in webapi.js. But I think it's not functional at the moment.
Another thing that may be interesting for you is my new port of this library to the chrome app platform. I just published a sample app: https://github.com/jdachtera/rtpmidi-chrome

Hello again jdachtera,
Sorry to bother you with this off topic question but i think there is no one better than you to ask about it, if you have time ill appreciate it, if you dont i will understand it perfectly.
Im trying to make a display for the timecode but im stuck with the way to pass variables between modules in node. This is what did to your example/mtc.js, i tried moving the http server without luck, i tried using socket.io but not sure if thats the way to go, so i ended using jquery on the http side and i get a value on screen but only of when i did the request, i have to refresh the whole thing to see a change in the code as the variable is filled only when i do the http request. If you have time, can you give me a hint or example of how i can handle in this scenario the node variables in the http module, or what do you think thats the best approach to achive this? (i replaced the brackets with - - so you can read it all)
Regards and thanks
