Use a provider to configure other factories

README.md

Like a Façade the ConfiguratorProvider take care of the entire app configuration.

So in your app instead of something like:

.config(function(firstProvider, secondProvider, thirdProvider){
    firstProvider.foo();
    secondProvider.bar();
    thirdProvider.baz();
});

you can have:

.config(function(configProvider){
    configProvider
      .foo()
      .bar()
      .baz();
});

You can keep all your app factories and use a single provider.

app.js

angular.module('app', [])
  .factory('Factory', function () {
    var foo = 'Factory (default)';

    function setFoo(value) {
      foo = value;
      return foo;
    }

    function getFoo() {
      return foo;
    }

    return {
      text: getFoo,
      setFoo: setFoo
    }
  })
  .provider('Configurator', function () {
    var text = 'Provider (default)';
    this.setText = function(value) {
      text = value;
      return this;
    };

    this.$get = ['Factory', function(Factory) {
      (function init(){
        Factory.setFoo(text);
      })();

      return {
        text: Factory.text
      }
    }];
  })
  .config(['ConfiguratorProvider', function(ConfiguratorProvider){
    ConfiguratorProvider.setText('Configuration');
  }]);
