var ServiceRegistry = require( 'br/ServiceRegistry' );
var EventHub = ServiceRegistry.getService( 'br.event-hub' );
Services are accessed via a ServiceRegistry and are identified by a unique string.
For example, a BladeRunnerJS application always has access to an EventHub service
(an in-app messaging system). This is accessed via the ServiceRegistry as follows:
var ServiceRegistry = require( 'br/ServiceRegistry' );
var EventHub = ServiceRegistry.getService( 'br.event-hub' );
In the upcoming exercises we'll see how to use some pre-defined ModularApp services.
As before, the real services aren't available yet. So, we'll need to use some fake service implementations to aid development that another team has kindly provided.
