Synchronize script calls with the help of socket.io and callbacks

Primary LanguageJavaScript

syncUp

Run code across tabs/browsers at the same time, by the help of a socket.io server and callbacks.

There is probably minimal uses for this, and its not that robust. I created this in a quick attempt to sync Web Audio API synthesizers/drums accross tabs.

Usage

  1. Start the server (default port 8080) node lib/server.js

  2. Add the script onto the page(s) where you want to run your stuff (you need to add socket.io-client as well).

  3. Connect the syncup's to the server

     syncup({
     socketUrl: 'http://localhost:8080',
     trigger: true,
     timeout: 5,
     callback: function() {
         console.log('tab #1');
     }
 });

This snippet will tell all other syncups connected to the server to execute their callback function in 5 seconds. If trigger had been false or not set, nothing would have happened until another syncup connected with the trigger flag set to true.
