Our Upcoming Presentations

July 25, 2018

Design Patterns are blueprints for common problems. Knowing patterns and being able to use them will help you to writte better code faster. In addition, once you are familiar with certain patterns, you will also spot them in other people's code. Last but not least, patterns are a common language for developers that will improve communication in your team. We will introduce five design patterns (Command, Strategy, Factory, Template Method, and Chain of Responsibility) every web developer should know and use. We will show example code, and discuss when and where to use each pattern.

Was macht sauberen Code aus? Wie wird Code richtig gut? Und wie schreibt man richtig guten Code? In diesem Workshop lernt Ihr das nicht nur, sondern Ihr könnt es auch direkt in die Praxis umsetzen! Zunächst demonstriert Sebastian Bergmann den Einsatz von Domain-Driven Design und Test-Driven Development, natürlich nicht ohne auch über Themen wie Clean Code oder die SOLID-Prinzipien zu sprechen. Danach arbeitet Ihr in Paaren und setzt das Gelernte in die Praxis um. Wir schließen den Tag ab mit einer Review-Runde, in der Ihr Feedback zu Eurem Code bekommt. Um von diesem Workshop wirklich profitieren zu können, bringst Du bitte Dein eigenes Laptop mit Deiner gewohnten Entwicklungsumgebung mit. Neben IDE (oder Texteditor) brauchst Du eine aktuelle Version von PHP und PHPUnit. Frameworks oder Third-Party-Code wird nicht benötigt.

Wer sicher sein will, dass Software richtig funktioniert, muss sie laufend testen. Das kann man entweder immer wieder manuell tun und entsprechende Kosten in Kauf nehmen, oder man automatisiert die Tests. Die Teilnehmer dieses Workshops lernen, wie sie das Werkzeug PHPUnit, den Standard für Testautomatisierung in der PHP-Welt, in ihren Entwicklungsprozess integrieren.

Developers usually have their favourite framework. But when did they choose it, and why? Was the decision rational, or rather emotional? This talk will not name "the best framework", but rather give the attendees a good background on how and why to choose frameworks and third-party-code in general. Topics covered include code quality, metrics, sustainability, and performing a general project assessment.

Implementing the business logic of your application in the object-oriented fashion requires more than knowing your favorite framework inside out and extending a controller base class. Avoiding tight coupling to the framework and hidden dependencies, we will develop business logic in a decoupled, fully tested and extensible way. Following the domain-driven design approach and test-driven development principles, we will develop a fully tested application. Most of the day, attendees will work in groups that are individually coached by the trainers. As we progress from understanding and documenting requirements to writing unit tests and working production code, we might even feel inclined to make use of some modern concepts like Command Query Responsibility Segregation (CQRS) and Event Sourcing. Please bring a laptop with PHP 7.2 and PHPUnit 7.2, and a decent IDE. We will need no web server, so please make sure that you can run PHP at the command line, and are able to execute tests with PHPUnit. We will need to frameworks or other third-party code.
