The Original European React Conference

ReactEurope is coming back on 23-24 May 2019 to bring you the best and most passionate people from the very core teams to the coolest people from the community we love.

After changing the way we think about state management in JavaScript applications, the way we write native mobile apps with React Native, how we interact with remote data with GraphQL or even how we manage CSS, the React community keeps innovating and its ecosystem growing.

At this conference, you will learn how new projects such as ReasonML will bring web and mobile React Native apps to the next level and how projects such as React Native Web, React Primitive and Expo make it easy to write, deploy and share code on all platforms quickly. The conference aims to give talks that inspire and explore new futuristic ideas dealing with all the techs we enjoy from the React ecosystem such as React.js, React Native, GraphQL, Relay, Universal apps, ReasonML, Webpack, inline CSS and more.

ReactEurope is also a great occasion to socialize, meet new people and old friends, hack together, taste delicious food and have fun in the beautiful city of Paris.

Join us at ReactEurope Conf to shape the future of client-side, mobile and universal applications!

React-spring is a popular React animation library that explores physics based UI animation. This talk will be about the state of React animation in general, the methods and techniques employed, the journey we took with react-spring, and how Reacts new hooks feature can change the way animation is supposed to work for the foreseeable future. Animated hooks can mend the gap between the declarative and the imperative and express intent more clearly, which has big implications on not only the moving thing itself but also with how we combine it with all the other things going on around it, from the data-model to user interaction.

Since the early 2000’s the name DJ Fresh has been synonymous with innovation. The cutting edge drum and bass sounds of drum and bass outfit Bad Company served as a backdrop to his early 2000’s tech startups, the award-winning forum Dogsonacid.com, and anti-piracy startup Darkstar LLC. But after 20 years of success in the music industry including signing acts like Pendulum and Chase and Status to his label Breakbeat Kaos and having the UK’s first ever Drum & Bass and Dubstep Number 1 records, Dan Stein contracted cancer, and after a narrow brush with death realised that he needed a change of pace. In 2017, he attended a Ruby boot-camp and two years later is a Machine Learning Developer at leading education research company HT2 Labs in Oxford, where his work has helped to win innovation awards. Stein believes that as our lives become more and more intertwined with technology that there are roles for everyone to be passionate about in the world of Tech. He’s here to tell us his story and explain why he thinks that developers are ‘Hot Right Now’.

Writing UI that can be accurately translated often comes with tradeoffs. If the text is sufficiently complicated, engineers have to take great pains (write conditionals, which are often error-prone) to ensure it is accurately rendered in other languages. Additionally, engineers are often either required to (a) keep strings separate from UI, or (b) keep translatable text simple enough to be extracted from UI source.

Fbt is an explicit markup language that tackles complexity and keeps UI text bundled with the relevant source code. This has the added benefit of keeping UI source self-documenting. This markup is parsed at build-time with text collected and sent to translators. The framework enables engineers to write text that would normally be tedious and error-prone in a succinct and accurate way.

Security and privacy are more important than ever in modern apps yet still continue to be an afterthought during the development and test cycles. Concepts around authorization, signing, and fine grained access control can be tackled and modern patterns such as GraphQL give us powerful tools to accomplish these requirements. This session will give details on lessons learned and solutions the AWS Amplify team encountered over the past year when working with customers building applications, and the differences implementing across React and React Native.

Forms are an ubiquitous element in the web. Most of web ecosystem tackled this subject years ago (Rails, Symfony, …), however, what about the JavaScript (especially SPA) ecosystem?

While most of current solutions (redux-form, Formik) provides full-features and widely used solutions, we are gonna focus on “typed forms”.

In a JavaScript ecosystem being more and more “typed” with the expansion of both GraphQL and TypeScript, why not take advantages of typed data? “Typed-data” means, no more duplicated logic between the back-end and the front-end (fields list, validation, etc).

We will explore an alternative way to manage forms using types and GraphQL.
