I have a working angular2 Component. I implemented a class for some service (using ng.core.Class if that matters). What are the minimal steps to inject my service to my Component? Should I include my service in bootstrap function? Should I use any of ng.core.Inject or ng.core.Injectable? All my experiments failed so far.

• javascript
• angular
• ecmascript-5

• I refer to current beta version of angular2 in this question. – Sergey P. aka azure Commented Dec 30, 2015 at 15:16

You can do it super simple. Just create a class an pass it through providers property or through bootstrap

For example

 // Alternative 1
 var Service = ng.core.Class({
  constructor : function() {},
  someFunction : function() {
    console.log('Some function');
  }
})

// Alternative 2
var Service = function() {}
Service.prototype.someFunction = function() {
  console.log('Some function');
}

Then pass it to the ponent

var Component = ng.core.
      Component({
        selector: 'cmp',
        template : '',
        providers : [Service]
      }).
      Class({
        constructor: [Service, function(svc) {
          svc.someFunction();
        }]
      });

Or through bootstrap

ng.platform.browser.bootstrap(Component, [Service]);

Here's an example so you can take a look at it.
