    Don’t Let Your Unit Tests Slow You Down
    Daniel Irvine
    Do your unit tests feel like a chore to maintain? Are they sometimes useful but come with a high maintenance cost? Do you secretly believe you’d work faster without them there? A great test suite should help speed up your development process, not slow you down. This talk highlights some techniques you can use to improve the front-end unit tests you write.
  • TBD
    React Native at Wix - Architecture For App in Scale
    Omri Bruchim
    Ever wondered how to use micro-services approach in a FED\mobile application? Hesitating to choose React Native for your big project? I’m here to eliminate the school of thought that React Native is mostly for small mobile applications.
  • TBD
    React-ing to tech debt
    Leonardo Garcia Crespo
    TweetDeck is complex application with a massive codebase that’s been around for more than 10 years. It started as an Adobe Air app, but the current codebase really started as a Chrome Web Store app. It once powered a windows app, and now it is a single page app that is accessed in a browser but also as a Mac app. It went through countless refactors, tech stacks, feature additions, removals and modifications, and lots of bugfixes and workarounds for now old browsers. As such, it accumulated technical debt and a lot of different coding paradigms. However, we managed to introduce React and successfully migrate several parts of the application, which allowed us to start moving faster again in those places. In this talk I want to show how we did that, some techniques and problems to solve when migrating an old codebase into React, and also learn to love what React gives us by looking at the problems we had before and how React removes them.
  • TBD
    Moving intensive logic Elsewhere.
    Alex Thomas
    With the recent publication of react-native-elsewhere, there is now a pure JavaScript method of decoupling computationally-intense operations from the UI thread. We’ll talk through how to take advantage of an <Elsewhere/>, tackle even tricky problems such as persistence, and work through it actually functions under the hood.
  • TBD
    Escape from React!
    David Miller
    You have an application that uses ReactJS in its view layer, but your Hot New Feature is not a good fit for React’s declarative programming model 😱! Oh no! Let’s explore some examples where that might be the case, and some strategies where React’s new(ish) Hooks API can help you escape from React and interface with non-React parts of your codebase.
  • TBD
    Build your own Native Module
    Patrick Loureiro
    Sometimes an app needs to access a platform API and React Native doesn’t have a corresponding module yet. Maybe you want to reuse some existing Objective-C, Swift or C++ code without having to reimplement it in JavaScript, or write some high performance, multi-threaded code such as for image processing, a database, or any number of advanced extensions. In this talk you will learn how to do that and see a real-world example.
  • TBD
    React Native: the Past, the Present and the Future
    Lorenzo Sciandra
    React Native is now 4 years old. During this time, we’ve observed more progression than ever before towards the vision of a cross-platform mobile solution. Even still, we have yet to realise its core mission of being as powerful as pure native. There have been many challenges that we’ve faced head on as they’ve surfaced. In overcoming them with the support of the community, we’ve managed to establish React Native as a force that is now defining the future of the segment.
    In this talk, we’ll explore this history-in-the-making before diving deeper into more technical subjects including the JSI & JSC upgrade, TurboModules & Fabric, and the CodeGen. With all the pieces of the puzzle in place and landing on master by end of the year, we are closer to reaching our original objective than ever before - while pushing the limits to a whole new level.
  • TBD
    What a Drag
    Vojtech Miksu
    "Can we do this thing drag and droppable?". That’s one of the sentences that every front end developer fears the most. There are many DnD libraries out there but did you ever consider building something from scratch before adding additional 100kB to your bundle?
    Let’s take a look what tools browsers offer today. You can build beautiful and accessible experiences while supporting mobile devices and not sacrificing the performance! This talk is inspired by the recently released react-movable library.


October 23-24

Take full advantage of your conference visit and get additional training from our best speakers and trainers.

Workshop programmes

Giving back to community

When we launched our first event five years ago, we never imagined we would welcome up to 1400 attendees at our events and organize four meetup groups and multiple spin-offs in Europe. Our secret? We welcome people from all walks of life in our community. We are a proud partner of initiatives like Unicorns in Tech, the global tech network for LGBT professionals and their straight allies.

We know that supporting diversity inside and outside of IT takes more than mere statements, which is why our diversity scholarship programs are a key part of every conference we organize.

In addition to our self-funded tickets pool, we're actively working with partner companies to sponsor more diversity scholarship tickets. Help make the React community a better place–support our scholarship programme!
