The Original European React Conference

ReactEurope is coming back in 2019. Last year's edition was on 17-18 May 2018 to bring you the best and most passionate people from the very core team 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!

This one-day workshop will teach you everything you need to know to incorporate GraphQL into your application. First, we’ll start by building a GraphQL server, covering best practices for architecting your schema, error handling, and caching. You’ll also be exposed to some advanced backend topics such as schema stitching.

Next, we’ll connect our GraphQL server to a React application with Apollo Client. We’ll break down the modular architecture of the client and teach you how to customize your own network interface through Apollo Link. We’ll also dive into server-side rendering and building query components with React Apollo. Throughout the course of the workshop, you’ll learn practical tips for using GraphQL in production from the engineers at Formidable Labs.

This workshop assumes participants have basic knowledge of GraphQL and intermediate knowledge of React.

I’m a sucker for web apps that make me smile.

This talk explores various ways that we, as front-end developers, can make our products more delightful to use. While it’s design’s job to give us static mock-ups, it’s our job to bring those designs to life.

For example, at Khan Academy, we fill the user’s screen with confetti rain when they get 100% correct on an exercise. I’ll talk about how we drew on 2D physics to make the confetti feel real.

Make no mistake; while this talk straddles the line between engineering and UX design, this is very much a React talk. I’ll show how to abstract motion and whimsical behaviour into reusable components, and how to do SVG/canvas animation in a React-friendly way. I’ll tear down some of my favourite examples from across the web, and show how to implement them in React.

Let’s play a game. What’s the biggest difference between type systems for JavaScript and an ML inspired language like OCaml or Haskell? Subtyping! Subtyping allows runtime values of some type to be used as a different type, and how a language designer chooses to address subtyping deeply affects every other design decision in the language. From the way values are represented in the runtime, to how effective type inference algorithms are, to the supported polymorphic code patterns. Implicit runtime subtyping is common in today’s most popular languages like JavaScript, Java, C#, and Ruby but the tradeoffs aren’t well understood. Subtyping is useful, but in today’s programming environment subtyping is overrated.

In 2017, Airbnb supported 27 languages and had developed robust translation tools that made it easy to add more. We launched Croatian in May with little overhead beyond setting up the new domain and translating phrases. However, this was not true for all new languages; our next most requested language, Hebrew, posed a unique challenge. Because it reads right-to-left, the entire Hebrew UI must be flipped. Browsers only handle reversing the DOM structure, but styling and interactions must be coded manually.

This talk covers the journey of enabling right-to-left languages on airbnb.com. Recently, Airbnb has moved to a React frontend and away from Sass to a CSS-in-JS paradigm. We developed a performant and cross-browser solution for RTL that leveraged a CSS-in-JS abstraction layer to isolate the logic from our codebase. Our efforts led us most of the way to launching in Arabic and Hebrew while requiring little effort from our product engineers and with minimal disruption to their work.

The React prop-types package is a simple runtime type system that is used for property validation. But runtime type systems can do many more things than just data validation. Because they are very flexible (as you can basically reuse the entire hosting language to express your types) it will be much less likely that you will run into structures that cannot be expressed in the type system. You can generate runtime types on the fly from other sources (json-schema, graphql etc) or compose them together.

In this talk I will walk you through some runtime type systems, like prop-types, tcomb and mobx-state-tree. But also show you how runtime- and compile-time typesystems like TypeScript or Flow can co-exist and leverage each other.

If you thought so far Higher Order Components or render callbacks where cool, in this talk I will show you that these patterns can be applied in general to any datastructure you have.

The talk introduces ReasonReact and the way it operates on the state of React components. This is illustrated by introducing the notion of local state presented via a series of examples. State is changed by means of reducers, that can operate directly on the current component, or on distant components via remote actions. Further examples illustrate how certain animations can be considered instances of local state that can be easily composed.

Navigation works in a wildly different way on Mobile apps than it does on the web. Why is that? We will explore how navigation state and URL handling tends to vary between the environments, and introduce a model that manages the complexity of both use-cases. Then, we will dive into the API of React Navigation to see how easy it can be to implement an app with fully-featured navigation on iOS, Android, browser apps, and server-rendered React sites!

React fundamentally changed how we build UI in JavaScript, yet the principles behind React are equally powerful outside the JavaScript ecosystem. What if we could build a design tool based on these principles, allowing us to design flexible, composable component systems? What if we could transpile these components into any language on any platform, such as a Swift components on iOS, or Kotlin components on Android?

In this talk, he ll demonstrate how React could fundamentally alter design and native development, just like it did for JavaScript.

Two months ago, I was working on a React project with a lot of SVG icons. I started to convert them into React components. I quickly figured out that it was a bot job and I started to look for a solution to do it. I found tons of projects but none of them matched my needs, so I decided to create my library.

I called it SVGR. The goal was simple, transforming a SVG into a React component. I coded it and I solved my problem, I saved a lot of time! I wanted to make it open source so I took the time to make a “beautiful” logo with a lion emoji and a good README. I also integrated Prettier in the project, I wanted to have a nice React code output out of the box. I tweeted it and got 40 stars and one contribution, I was happy.

Two weeks ago, Christopher Chedeau tweeted about my library, two hours later React Europe also tweeted it, later that day I got a star from Dan Abramov. Next thing you know I was trending on GitHub, getting 1K stars in one day!

What is the future for SVGR?

We’re Progress. We make software that developers love. We’ve heard that you’re a big fan of React, which is great, because we are too. In fact, we make a pretty awesome tool for React that you really need to know about: Kendo UI. Kendo UI is a set of modular UI components you can use to enhance your apps—think calendars, grids, charts, and such. Sure, there are other grids and charts and stuff out there, but not like ours. See for yourself! You’ll find features that you just won’t see elsewhere. We even make it easy to use our components, too, with popular out-of-the-box themes and a custom theme editor. Pretty cool? Our customers seem to think so.
Come find us to chat about Kendo UI, grab some swag, and enter in a drawing.
