How do we do that
with OSGi™?

What do we have
in JavaScript ?

Module Patterns
+ -
Fix visibility A bit complex
No interfaces

Module loaders
+ -
Avoid <script>
Transitive
Reuse
Hard-coded
dependencies

MVC / MVVM
+ -
Code
organization
UI Bindings
Pushing
the limits

Run
h-ubu
Cordoba
play2, grails

Something close to
OSGi™ : h-ubu

Service-based
Injection
Framework

var component = {
configure : function(hub, conf) { },
getComponentName : function() { },
start : function() { },
stop : function() {}
};
hub
.registerComponent(component)
.start()

var myService= {
doSomething : function() {}
}

services
Service
Registry
1 - Publication2 – Lookup,
Service Listener 3 - Binding

Why services ?
Substitutability
Loose-coupling
Testable
Dynamic

var provider = {
configure : function(hub, conf) {
hub.provideService({
component: this,
contract: myService
});
},
start : function() { },
stop : function() {},
doSomething : function() { … }
}

var consumer = {
hub.requireService({
component: this,
contract: myService,
field: "svc"
});
},
start : function() {},
work : function() {
this.svc.doSomething();
}
}

var consumer = {
hub.requireService({
component: this,
contract: myService,
field: "svc"
});
},
work : function() {
this.svc.doSomething();
}
}
Proxy

var publisher = {
configure : function(hub, conf) {}
work : function() {
this.hub.publish(this, "my/topic",
event);
}
}

var receiver = {
hub.subscribe(this, "my/(.)*?",
this.receive);
},
receive: function(event) { }
}

Modularize your
JavaScript
require.js/node.js
Composition
Standalone
Configurability

Stop hacking,
Start composing
