Talks

Domain Driven Design focusses on modelling the domain logic. This talk looks at the components of the model layer of your web application and the options you have. How are you supposed to organise your models in an MVC application? What goes where? What is a service class, a mapper or an entity? We'll discuss the terminology and take a look at what Domain Driven Design is and see how you use service layer to provide the business logic for your application and hide your persistence code from your controllers. By the end of this session you will be equipped to create excellent, maintainable models in your projects.

Building line-of-business web applications for clients with traditional IT departments brings its own set of challenges when it comes to DevOps. In particular, the IT department adds additional constraints that you may not see in more forward-thinking companies. Rob Allen explores these complexities and shares some solutions he and his team came up with in order to use modern development practices in nontraditional environments. You’ll learn how CI tools with appropriate scripting enable reliable delivery of a quality product on IBM i and Windows. Rob also covers the organizational and technical challenges encountered when IT departments are not used to developers having a say in the server environment and shows you why it’s worth spending time getting them on board.

Apple has open sourced Swift, their new programming language, so you can now use it on Linux servers. Swift's static typing, concise syntax and speed make it a good language for all types of server-side software including APIs. In this session you'll learn how to build an API in Swift 3. We'll cover the key concepts around HTTP request-response resource APIs, including accepting and generating the correct content type, routing, authentication and also returning errors appropriately.

We all know that the M in MVC stands for model, but what does that actually mean? Domain-driven design helps us map our software to the business requirements of our clients, but it can be quite hard to understand. In this talk I explored the fundamentals of Domain Driven Design and showed how to apply it to the design and implementation of the business logic of your application.

Everyone is writing APIs from micro-services through to full applications, but what makes a good one? In this session we’ll go back to the basics and look at what I consider to be five of the more important architectural features that you should think about when creating an API. These are the features that ensure that your API plays well with HTTP and, more importantly, make your API a delight to maintain and work with. I want you to ensure that your API is a good HTTP citizen, while also providing developer-friendly features like thoughtful error handling and documentation.

Slim is a PHP micro framework that enables you to write powerful web applications and APIs. In this talk, I will show how you can easily write great web sites with it. We will look at how Slim's middleware system leverages the PSR-7 HTTP request and response definitions to create easily understandable and flexible applications. We will cover application setup, routing and the relationship between actions and middleware. By the end of the session, you will be equipped to create Slim applications yourself.

Accessing web services from your application is a key requirement and the best HTTP client library for PHP is Guzzle, which happens to be included with Drupal 8. Learn how Guzzle makes accessing APIs a breeze – we'll cover how web services work and then how Guzzle makes it easy for us to send and receive the data we need, including working with Authentication. We'll also cover the PSR-7 standard Requests and Responses, and how Guzzle makes them easy and effective to use in your own applications including the powerful middleware system.
