TIPS, INSIGHTS AND THE LATEST FROM THE EXPERTS BEHIND CAKEPHP

Meet the CakeDC

The articles section of our site will include best practices, business advice, and technical advice, updated weekly or more often by our talented developers. Our articles will touch upon a wide range of topics from our experiences and expertise. Check back frequently for fresh thoughts from our seasoned talent, including Mark Story who was at CakeFest in Argentina providing updates daily on the talks.

As a founder of and lead developer at the Cake Development Corporation, I am proud to provide the inaugural article for the all new CakeDC.com. It has been a long and wonderful last 12 months, and CakeDC has helped bring reality to the limitless potential of our clients' projects. Like any great recipe, the ingredients of Cake Development Corporation have been hand–selected and carefully measured to create the very best blend of talent, imagination, and sophistication of any team in the world. It is my great pleasure to introduce you to our outstanding development team, as well as provide a little background about where our company has come from and where we are headed.

After spending nearly 2 years working exclusively on CakePHP and seeing its popularity growing daily, Garrett Woodworth and I realized the need for a team of experts devoted to building the best applications for clients. Therefore, in 2007, Garrett and I formed Cake Development Corporation – a company dedicated to bringing the potential of CakePHP to life while supporting its further development and aiding clients in the rapid development of web applications. In this venture, Garrett and I recognized that we had a unique and rarely realized opportunity to do what we love as our full–time jobs – and, unlike during those initial two years of development, actually get paid to do it.

As a business partner, I could not have asked for anyone better than Garrett. A key player in the development of CakePHP, Garrett continues to develop the code and drive the machines that keep users coming back for more. He is extremely passionate about the work he does and takes pride in delivering quality products that are the best of their kind, a true leader the team members can look up to. In fact, I have come to think of him as a younger brother – someone whom I respect greatly, but with whom I also spar from time to time (in a healthy way, of course).

After a short time, it became necessary to bring on some new talent. Garrett and I welcomed a third developer Jitka Koukalová, to our small family in 2007. Jitka, a developer who was active in the CakePHP community and was vital contributor to its code, was an amazing addition to our team from the beginning, and exhibited great skill in, and equally great appreciation for, our open source platform. With great attention to detail, she became instrumental in server security and maintenance. Her ability to find an issue and fix it fast along with her classy and professional demeanor would make her a mentor to future members of the Cake development team.

Florian Krämer, the next to join CakeDC, soon became our second great recruit. Florian has continually proven himself to be extremely knowledgeable when it comes to developing applications. Florian's meticulous attention to detail, outstanding work ethic, and dogged pursuit of excellence continue to be hugely important assets of our company. But more than a colleague, I consider Florian a good friend. Apart from his great skill, his fun and personable demeanor make him a great team member and someone I genuinely enjoy working with. He has a great sense of humor – or, at least, he appreciates mine!

Having seen a great deal of growth in 2007, we sought to expand our development team in early 2008 by welcoming aboard a whole new crop of distinguished developers with a great working knowledge of CakePHP and a passion for its vast capabilities. The first of this group was Yevgeny Tomenko. Yevgeny knows an astounding amount about the inner workings of application development, and I am continually amazed at his dependability and sheer speed. Since joining our team, he has become a great "go–to" person who uses his years of experience to help guide the others on the team. I really love how passionate he is about our product, and it’s great to see such a talented and focused guy enjoying his work at CakeDC.

Next, after spending some time watching Niles Rowland help others in the CakePHP IRC channel, we realized he would be a true asset to the CakeDC team. We recruited him in early 2008, and since then he has been a very knowledgeable and dependable part of the development team with a vast understanding of CakePHP and programming in general.

Soon to follow Niles were Erin McCargar and Daniel Feinberg, both of whom came aboard in May of 2008. Erin has a long history working with CakePHP and is looked up to as an advisor by those on her team. Daniel, a key person when it comes to machine learning, is very knowledgeable with CakePHP. With outstanding attention to detail and a great skill in their fields of expertise, both are willing and able to go the extra mile to make a project shine.

Finally, our most recent addition to the family is Mark Story who joined the team in November of 2008. Mark brings a lot to CakeDC; he is a core developer of CakePHP with design experience that is second to none. Mark is all about getting things done right the first time, and is great at working with others. The rest of the team truly looks up to him for both his skill and amicable personality.

This eclectic group of talent is the heart and soul of CakeDC, the family unit that makes our company stand a head and shoulders above the rest. After seeing how far we have come in the last two years, I am very excited to see what this team can accomplish next! We are looking forward to all the challenges that lay ahead and can’t wait to help our clients create a brighter, more innovative future.

CakeFest 2021 Recap

Here we are again coming off of the CakeFest sugar high! I don’t even know where to begin.    Unfortunately, or fortunately - I haven’t decided, we had to do another virtual event. The safety of speakers, staff and attendees is very important to us, so a physical event was not the best option in our opinion with traveling.    However, after this event, I started thinking about the people who were able to attend from the comfort of their own homes or offices. These people may not have been able to travel or attend otherwise, and that gives me our silver lining. Not to mention that we had more ticket sales this year than any of our previous events (at least that I can remember).    The theme, for me anyway, ha ha, was traveling the world, ironically. We started in the Canary Islands, traveled to Germany, to Canada, to England and Austria. We had new faces from the US, the Czech Republic and even Japan - and more! This is, as I’ve mentioned, one of the best things about the CakePHP community, we have community members all over the world. This was our chance to come together.    So let’s get to the event. Here’s what you may have missed:

Trivia and giveaways 

Cake ceremony dedicated to Mark Story

We took this time to thank and acknowledge Mark Story for all of his hard work and dedication that he puts into CakePHP. He then headed the cake cutting ceremony (virtually of course) as speakers and attendees enjoyed their own treats!   See the full archive here: https://cakefest.org/archive/virtual-2021  

So what’s to come? 

First!  Videos are starting to be released. With the help of community member Aroop Roelofs, we will be releasing these videos faster than expected. Ticket holders have been receiving access, and they will be released publicly in the coming days.  In regards to future events, it’s up in the air. We will have some internal discussions about safety measures and restrictions, then we will weigh the option between another virtual or physical event. We will, of course, reach out to the community for their input.  I will close by just saying THANK YOU. Thank you for making my job worth it. When an event runs smoothly and gets so much great feedback, that is a direct reflection from the community support. We hope you all will continue to join us in years to come!    Thanks for baking!  

Dependency Injection with CakePHP

Let’s talk about Dependency Injection!

SOLID principles

As you know SOLID is an acronym for the  five object-oriented design principles. In this topic, we will focus on Interface segregation principle and Dependency inversion principle. Interface segregation principle states that a client must not be forced to implement an interface that they do not use, or clients shouldn’t be forced to depend on methods they do not use. In other words, having  many client-specific interfaces is better than one general-purpose interface. From the other side, Dependency inversion principle states that objects must depend on abstractions, not on concretions. It states that the high-level module must not depend on the low-level module, but they should depend on abstractions. To follow Dependency inversion principle, we need to construct low-level modules and pass them to constructors, and that might create a lot of manual work for developers. The dependency injection container is created specifically for solving the problem with manual construction of an object, before creating a specific object. If we follow interface segregation principle when developing application modules, it would be easy to configure a container and switch module dependency. This is where the interface shows its incredible power.  

Few words about CakePHP Events System

CakePHP Events System was created to allow injecting some logic using listeners. However, in some cases, it is used to get results from code that will be created by the module user. When an event is dispatched by the listener, it can return the result. Callback injection through the event system has some drawbacks. First of all, parameters passed to the event need to pass as a hash array. So unfortunately, there is no way to check that all params are really passed or to be sure that all passed params have correct types. Is there a way to solve this problem? Yes, and containers could help with that. Instead of passing events, we can get the required object from the container and call it method. But you could say: wait, we don't know what object could be used in client code within the developed plugin. That's fine, and this  is where interface segregation principle can help. In our plugin, we define an interface for each such case, and instead of dispatching an event, we can easily get an object from the container by interface.       $updater = $container->get(AfterLoginInterface::class);     if ($updater !== null) {         $user = $updater->afterLogin($user);     }   In the Application::services method, users link the interface with the specific class.       public function services(ContainerInterface $container): void     {         $container->add(AfterLoginInterface::class, MyAfterLogin::class);     }   In some of default behavior needed we can map service class for container to default implementation using Plugin::services method.       public function services(ContainerInterface $container): void     {         if (!$container->has(AfterLoginInterface::class)) {             $container->add(AfterLoginInterface::class, NullAfterLogin::class);         }     }  

Container propagation

Dependency injection is an experimental feature. Initial implementation limited by Controllers constructors and methods, and Commands constructors. If we want to access the container in other parts of the application, we may want to propagate it from app level. The most logical way would be to implement middleware and store the container inside the request attribute.   <?php declare(strict_types=1);   namespace App\Middleware;   use Cake\Core\ContainerInterface; use Psr\Http\Message\ResponseInterface; use Psr\Http\Message\ServerRequestInterface; use Psr\Http\Server\MiddlewareInterface; use Psr\Http\Server\RequestHandlerInterface; use RuntimeException;   /**  * Container Injector Middleware  */ class ContainerInjectorMiddleware implements MiddlewareInterface {     /**      * @var \Cake\Core\ContainerInterface      */     protected $container;       /**      * Constructor      *      * @param \Cake\Core\ContainerInterface $container The container to build controllers with.      */     public function __construct(ContainerInterface $container)     {         $this->container = $container;     }       /**      * Serve assets if the path matches one.      *      * @param \Psr\Http\Message\ServerRequestInterface $request The request.      * @param \Psr\Http\Server\RequestHandlerInterface $handler The request handler.      * @return \Psr\Http\Message\ResponseInterface A response.      */     public function process(ServerRequestInterface $request, RequestHandlerInterface $handler): ResponseInterface     {         return $handler->handle($request->withAttribute('container', $this->container));     }   That’s it! I hope that this will help you when you are baking with dependency injections. If you run into any problems, there are many support channels that allow the CakePHP community to help  You can check them out under the community tab at CakePHP.org.

One CakePHP Project Per Day
