Usage

For example, collector is a module that request and update real-time data from all exchanges. When it gots new exchange's feed (ohcl). It will trigger an event to inform to all listeners :

let event = new NetworkEvent();
event.setNetworkName('collector').setEnv('development');
event.registerEvent('newFeed').then((result) => {
   //Event registered successfully
});
//Get OHCL from and exchange
onGetNewFeedSuccess().then((feed) => {
    event.triggerEvent('newFeed', {feed : feed});
})

Next, analytics is a module which always wait for exchange feed update and recalculate new indicator values. It needs listen newfeed event of collector module.

let event = new NetworkEvent();
event.setNetworkName('analytics');
event.addListener('collector', 'newFeed', function(feed) {
    //New feed received. Start recalculate...
});
