Example Usage

// define a dummy hello world service
var Acme = function (name) {
  if (name) {
    this.sayHello(name);
  }
};
Acme.prototype.sayHello = function (name) {
  console.log('Hello ' + name + '!');
};

// define some initial parameters to start with
var someParameters = {
  username: "sweikenb"
};

// create the dependency container (if you don't have initial parameters just skipp the arument)
var container = new Dicon(someParameters);

// add a new parameter "on-the-fly"
container.setParameter('repository', "https://github.com/sweikenb/dicon.js");

// register the acme service and add the "username"-parameter as dependency
container.register('acme', Acme, ['%username%']);

// define a service "on-the-fly" and add the "acme"-service and the container itself as dependency
container.register('helloWorld', function (acme, container) {
  acme.sayHello('World, please have a look at: '+container.getParameter('repository'));
}, ['acme', '&']);


// HINT: if you like to inject the container itself as an dependency use the special '&' service-id.


// request the services
var greeter = container.get('acme');
container.get('helloWorld');

// call a service method
greeter.sayHello('Octocat');

This will return:

Hello sweikenb!
Hello World, please have a look at: https://github.com/sweikenb/dicon.js!
Hello Octocat!
