// For this example i use angular $http service but you could
// replace it with other with similar interface
let http = angular.injector(['ng']).get('$http');
// Registry for new Resource classes
let registry = new arekzc.resource.registry.ResourceRegistry();
// Create configuration to set defaults for resourceManager service
let configuration = new arekzc.resource.configuration.Configuration(registry);
// Create instance of resource with provided services
let resourceManager = new arekzc.resource.ResourceManager(http, configuration);
// Get new resource based on metadata added by Reflect library
resourceManager.create(Book).get(1);

Javascript

	this.title = undefined;
}

Reflect.defineMetadata('Url', new arekzc.resource.resource.UrlGenerator('/books/{id}'), Book)

// replace it with other with similar interface
var http = angular.injector(['ng']).get('$http');
// Registry for new Resource classes
var registry = new arekzc.resource.registry.ResourceRegistry();
// Create configuration to set defaults for resourceManager service
var configuration = new arekzc.resource.configuration.Configuration(registry);
// Create instance of resource with provided services
var resourceManager = new arekzc.resource.ResourceManager(http, configuration);

resourceManager.create(Book).get(1);
