The pool manager will allow you to subscribe to more channels than the maximum recommended.
// Init
var pubnub = require('./pnpool')( 25, {
publish_key : 'demo',
subscribe_key : 'demo'
} );
// Subscribe to Many Channels
pubnub(channel).subscribe({
channel : channel,
message : function(msg) { console.log(msg },
});
// Send Message
pubnub(channel).publish({
channel : channel,
message : channel
});
