Provider Creation in AngularJS

createProvider

var app = angular.module('capeloMod', []);

app.provider('demo', function() {
    var cfg = 'Default';
    this.setCfg = function(providedCfg) {
    	cfg = providedCfg;
    };
 
    this.$get = ['dependencyName', function(dependency) {
        return new dependency(cfg);
    }];
});

// we can now set a custom cfg before the app starts, on the 
// configuration phase of the application life-cycle:

app.config(["demoProvider", function(demoProvider) {
  demoProvider.setCfg({stuff: true});
}]);
