ClojureScript Workshop (3h)

GraphQL Workshop (3h)
GraphQL has drastically changed the way how we interact with APIs by providing a strongly-typed layer for client-server communication. This notably improves performance by letting clients request the specific data they need using a simple and declarative syntax. Thanks to the GraphQL schema which serves as the contract for all possible API operations, GraphQL further introduces many benefits to local development workflows (such as compile-time error checks and editor auto-completion) and the overall API tooling space.
In this workshop, you will learn how to build a fully-featured GraphQL server (including realtime GraphQL subscriptions) with Node.js that takes advantage of the latest GraphQL tooling and is based on a modern stack.
at THTMaurice de Beijer
Advanced React Components Workshop (3h)
In this half day workshop, you are going to learn how to create better React components. We will start of simple and compare controlled versus uncontrolled components and when you want to use which of the two options. Then you will learn how to use the React.Fragment class to reduce the number of DOM nodes you need to create at runtime.
After the intro you will learn how to use Reacts Component componentDidCatch() lifecycle function to catch errors and make your applications more resilient to failure. We will also take a look at the sorts of errors that componentDidCatch() doesn’t catch for you.
Next you will learn about two different ways of adding cross cutting concerns like error handling to React components. First, we will look at creating higher order components like the Redux connect function. While higher order components are a great way of extending components, they aren’t without their drawbacks. So, we will investigate an alternative approach using render props. This is another great mechanism, and a more flexible approach as well.
Finally, you will learn how to use the new React Context that will ship with React 16.3 to make it even more convenient to pass data from one component to another

Progressive Web Apps workshop (3h)
Progressive Web Apps are the latest iteration in modern web development. It's an open, cross-browser technology meant to improve user experience on the mobile web. It enables push notifications, working offline and can provide a native app experience. In this workshop you'll learn what to consider when building a PWA and get some hands-on experience in setting up a Web App Manifest and a Service Worker. This workshop assumes basic working knowledge of ES6 and the Fetch API.
at THTIvan Jovanovic
After this workshop, attendees will be able to efficiently test their JS applications, from UI frontend side to backend side. They will understand what are the best practices and best tools for building testing environment.
Keynote: The Power of the Paradigm
Bringing Mobile Web back to Life
We rebuilt the whole Pinterest mobile web experience for authenticated users. It looks and feels just like our native apps while maintaining the fast load times expected of mobile web. We used cutting edge technologies which led to a 40% increase in each of our core engagement metrics and up to 30% in time spent. But it was not all sunshine and rainbows ! In this talk I will share challenges, technologies and best practices that we used for the new Mobile Website.
Vue JS Best Practices
At GitLab we use Vue JS in production more than a year. I refactored old parts of GitLab with Vue and created many new features using the framework. We are really impressed how Vue is simple yet powerful. First 10 mins of the talk are an introduction for new comers, then deep dive into the best techniques, like state management, reactivity, tooling and also the experiences about new feature development and migrating a legacy featue to Vue.
TypeScript Ruined My Life (In a Good Way)
No matter your experience in JS, you have probably came across the Array#sort method at some point. Do you remember the first time you tried sorting numbers? You were probably astonished that the sort method does not sort things out quite as we might expect. Believe it or not, there is actually much more going on than meets the eye! Let’s get our computer science hat on and explore some useful sorting algorithms currently implemented by JS engines used by Node such as Chrome's V8 and Microsoft's Chakra. As a developer, learning how these algorithms work, why and when to use them will help you create more performant and consistent applications!

Look ma! No hands!
The main points of the presentation will be focused on tips and best practices regarding WebXR UX. I will have a several VR devices ready to show how an experience can be adapted to run independently of the hardware that's available to the user. Main point is to teach developers how can they make their content truly accessible with as little as possible.
How to scale an SPA?
I'm going to tell you a secret. If you are building an SPA, you can take advantage of optimisations that give you epic scalability, with super low latencies at a fraction of the cost. To understand the secret, I'll need to teach you a few things such as the actors involved in transferring data from your server to the browser; and about the ancient technology called 'serverless' which you might be surprised to learn is something you've already been using for years. By the end, you'll know the secret of how to architect an SPA for scale without breaking the bank.

The dark ages of IoT
Advertisements suggest that we are at the zenith of mankind's scientific knowledge and technological power, but when it comes to IoT and the so-called 'Smart Home', we are clearly not. In fact, we are in the middle of the dark age. I'll explain the challenges that we're facing today (from an implementors perspective), what's 'wrong' with our current products & show you how a smart 'Smart Home' experience could look like in the near future.

ECMAScript Modules: Past, Present, and Future
Since last year, all major browsers support ECMAScript modules, and Node.js is looking to support them as well. Join me for a tour! I will tell you about the history behind the feature, compare it to other JS module systems, explain the new syntax forms and their meaning, discuss some of the pitfalls, and give an overview of proposed extensions.
Optimized Angular apps: smaller, faster, better
Angular apps are getting more performant with each new version of the framework - thanks to the huge number of internal optimizations. But the main responsibility for the eventual app performance is on us, developers. Let's go through the main points on how we could help the framework to build and the browser to perform our app better.
Building functional Front-ends with ClojureScript
Clojure came along into our lives in 2007 as one of the most concise and powerful Lisps, and since them it's been widely adopted by members of the community. Recently, Clojure got a new friend called ClojureScript, which allows us to use Clojure to build robust and reliable front ends. Ever wanted to use a rich data structure set, macros and take advantage of the great performance optimizations present on the JVM? You got it! In this talk I'll go through the super powers ClojureScript can add to the view layer and the benefits of functional programming.
In the Ocean of Angular Web Applications
An online retail website is just the tip of the iceberg hiding a mountain of complexity. Let me walk you through the depths of microservices powering a plethora of Angular applications at bol.com, the biggest webshop in the Netherlands and Belgium - BOL.COM
Mock to start
When you are developing an application that uses remote REST API endpoints, it will be hard to implement a new feature that has not an API implementation yet. Also always you need to have a running API server to continue development. Then, you probably will have some troubles to test some very exceptional issues because it's hard to reproduce that kind of issues. All of these problems can be managed with a very simple client-side mocking approach. At this talk, we will talk about that approach and and how it is easy implementing a client-side mocking solution with connect-api-mocker library.
