A resource oriented framework

Scrutinizer Code Quality Code Coverage Build Status

What's BEAR.Sunday

This resource orientated framework has both externally and internally a REST centric architecture, implementing Dependency Injection and Aspect Orientated Programming heavily to offer you surprising simplicity, order and flexibility in your application. With very few components of its own, it is a fantastic example of how a framework can be built using existing components and libraries from other frameworks, yet offer even further benefit and beauty.

Everything is a resource

In BEAR.Sunday everything is a REST resource which leads to far simpler design and extensibility. Interactions with your database, services and even pages and sections of your app all sit comfortably in a resource which can be consumed or rendered at will.

GET - Hello World

The resource class receive a named argument over the query parameters of the URL.

class Hello extends Page
    public function onGet($name = "World")
        $this['greeting'] = "Hello " . $name;
        return $this;
<!DOCTYPE html>
<html lang="en">

Building a Hypermedia-Driven RESTful Web Service in 1 min

Hypermedia is an important aspect of REST. It allows you to build services that decouple client and server to a large extent and allow them to evolve independently. The representations returned for REST resources contain links that indicate which further resources the client should look at and interact with. Thus the design of the representations is crucial to the design of the overall service.

Create project

composer create-project bear/skeleton:~1.0@dev MyVendor.MyPackage
cd MyVendor.MyPackage
composer install

Create a resource class



namespace MyVendor\MyPackage\Resource\App;

use BEAR\Resource\ResourceObject;

class Greeting extends ResourceObject
    public function onGet($name = 'World')
        $this['greeting'] = 'Hello, ' . $name;

        return $this;

That's all.

Test the service

Use the built-in PHP server.

php -S localhost:8080 bootstrap/api.php

Now that the service is up, visit http://localhost:8080/greeting, where you see:

    "greeting": "Hello, World",
    "_links": {
        "self": {
            "href": "/greeting"

JSON representation of a greeting enriched with the simplest possible hypermedia element, a link pointing to the resource itself:

Congratulations! You’ve just developed a hypermedia-driven RESTful web service with BEAR.Sunday.


Application execution sequence is scripted by the user-defined application script.

Application services are just stored in one object variable. You can access all resource of application with resources clients, easy use from plain PHP files or CMS and other frameworks as well.

Dependency injection

It is google guice style DI framework.




public function __construct(Annotations $reader)
    $this->reader = $reader;

Aspect oriented programming

Many features of the framework are implemented as an aspect.


class WeekendBlocker implements MethodInterceptor
    public function invoke(MethodInvocation $invocation)
        $today = getdate();
        if ($today['weekday'][0] === 'S') {
            throw new \RuntimeException(
                  $invocation->getMethod()->getName() . " is not allowed on weekends!"
        return $invocation->proceed();


class RealBillingService implements BillingService
     * @WeekendBlock
    public function chargeOrder()

Weaving an Interceptor


RESTful Service

Resource object fusion resources and web PHP class.

Resource object

class Greetings extends AbstractObject
    public function onGet($lang = 'en')
        $this['greeting'] = $this->message[$lang];
        return $this;

Resource client

use ResourceInject;

$this->resource->get->uri('app://self/greetings')->withQuery(['lang' => 'ja'])->eager->request();
