Services

Singletons

[Style Y040]

  • Services are instantiated with the new keyword, use this for public methods and variables. Since these are so similar to factories, use a factory instead for consistency.

    Note: All AngularJS services are singletons. This means that there is only one instance of a given service per injector.

  // service
  angular
      .module('app')
      .service('logger', logger);

  function logger() {
    this.logError = function(msg) {
      /* */
    };
  }

  // factory
  angular
      .module('app')
      .factory('logger', logger);

  function logger() {
      return {
          logError: function(msg) {
            /* */
          }
     };
  }
