    The power of interpolation

    Mike Grabowski, Poland

    One of the biggest benefits when choosing React Native is its declarative nature. Instead of laying out elements on screen manually, we tell React how our interface should look like for a given state. That, combined with React Native taking care of rendering, allows us to write things that would be hard or even impossible otherwise. One of such things are animations. Historically, we used to write them in an imperative and stateful manner. By design, these are hard to debug and - most importantly compose. In this talk we will take a look at writing animations in React Native by using Animated module.

  • 10:10

    Keep Your Sanity with Redux Sagas

    Tyler Clark

    Pluralsight, US

    Redux is a strict framework. Whether you view that as a pro or a con, handling async actions can sometimes be a pain. Especially if you are using middleware such as Redux Thunk and have to chain promises.

    As an application grows, it's difficult to maintain and continuously test these actions. By the use of the ES6 generator function, Redux Sagas break up async actions into synchronous events. This makes it easier to test, chain actions that depend on the result of each other, and deserialize promises.

  • Humanizing Your Documentation

    Carolyn Stransky

    Contentful, Germany

    It’s no secret that people don’t usually read technical documentation for pleasure. Users often come to your docs when they are frustrated, disappointed and at their lowest. In this talk, we’ll discuss how the language we use affects our users and the first steps towards writing use case-driven, accessible docs.

  • Data Driven Styling

    Oleg Slobodskoi

    Grape, Germany

    While all CSSinJS solutions try to improve API's for describing static styles, not many actually know how to solve dynamic styling. Let me show you how we can completely forget inline styles.

  • Add Powerful Components to Your React Apps

    Olga Petrova

    Sencha, Germany

    In this presentation, you will learn how you can add powerful components to your React apps.

Learn how you can build data-intensive, cross platform applications using React and powerful components from commercial libraries.

  • Jest & Enzyme complement each other.

    Manjula Dube
