What is BEAR.Sunday?

BEAR.Sunday is a framework for creating elegant, truly RESTful API centric web applications in PHP.

It helps you to create beautiful decoupled object orientated code. How does it do this?

Object Frameworks

Many web frameworks give you lots of components, modules and features. BEAR.Sunday however gives you just 3 consistent framework patterns into which you can then wire up to your favourite libraries and custom gizmos.


Ray.Di is a modern and powerful Dependency Injection framework that enables this unobtrusive wiring up of dependencies, libraries and instantiated PHP objects.


Ray.Aop is an Aspect Orientated Programming framework that allows you to wrap objects with other objects by binding them together. This is great when your core business logic should have no knowledge that it is being wrapped by for example an authentication or logging aspect.


BEAR.Resource allows you to treat all entry points to your app as RESTful resources. Resources can then be consumed uniformly across your app. This can be done externally via HTTP or internally via the resource client.

Treating all of your data as a resource then simplifies the how you get to your app.


BEAR.Sunday is not like other MVC frameworks that contains libraries that support databases, authentication or the likes.

Instead, you can hook your own great libraries that are available on Packagist like the Aura component libraries.

Resource Orientated Pattern

BEAR.Sunday does not follow MVC instead it is a variation of Resource-Method-Representation


Resource state is created by calling stateless requests on RESTful methods, the internal renderer then handles the representation and becomes the response.

class Index extends ResourceObject
    public $code = 200;
    public $headers = ['access-control-allow-origin' => '*'];
    public $body = [];

    private $renderer;

    public function __construct(RenderInterface $render)
        $this->renderer = $render;

    public function onGet(string $name) : ResourceObject
        // set resource state
        $this->body = $state;

        return $this;

    public function __toString()
        // contextual renderer makes representation (JSON, HTML)
        return $this->renderer->render($this);

    public function transfer(TransferInterface $responder, array $server)
        // contextual responder output (CLI, HTTP)
        $responder($this, $server);


What initially makes up a web application is a group of resources. In BEAR.Sunday these can be created as Resource Objects. (Object as a service) The resources can then be accessed locally via PHP or by HTTP requests. In both cases using a consistent URI interface. Each Resource object can then be exposed as a service either or both inside and outside of your application. Using Hypermedia using specially provided annotations you can either @Link or @Embed other resources.


Each resource object is accessible through an HTTP verb based method. HTTP parameters can also be specified in the method and are then able to be passed in. Once invoked resource properties can then be constructed inside this method. Just like in a controller action in an MVC framework other domain models or resources can be called and accessed.

Method construction can then be built up using a variation of Onion Architecture or Clean Architecture. Logging, validation or authentication etc can then be implemented using Aspect Orientated Programming wrapping the original target method.


Each resource has the representation of its current state rendered through an injected renderer. Methods themselves do not know anything about a representation’s existence at all. This representation is handled by the resources’ Responder

Clean Method


  1. A web handler transforms a client request into an application resource request.

  2. The Method that received the Resource request then constructs itself (the resource).

  3. The resources assigned Renderer then renders the string value Representation of that resources state.

  4. The Responder returns the Representation to the client

Why a new pattern?

The conventional object orientated pattern maps an application to HTTP. Controllers know nothing about HTTP or REST.

In this new pattern you create an object that is mapped to HTTP. Making REST the framework in which do your development in. Unlocking the power of REST this Resource Orientated pattern allows you to use HTTP as the application protocol.
