React Day Berlin

In this talk Tomasz would like to show you how YOU can start covering your app with e2e tests and showcase coolest features that cypress.io has to offer.

Building GraphQL apps in React is no easy feat but is hugely simplified by GraphQL clients that intelligently take schemas and types into account. In this talk, we'll explore what a newer more flexible version of the urql library will look like, and how it encourages experimentation so you can build your own, custom GraphQL client more easily.

Redux and Context are frequently discussed as competing state management solutions. Redux is strengthened, but also sometimes limited by its prescription of "one true global store." This talk discusses a synergy between the two technologies to address this 'limitation' in certain cases.

This talk will explain how context and render props work and give you some ideas of how to use them to simplify your own code.

Large applications cannot be structured the same way as small applications. Many good decisions you make for a small application suddenly become bad once it grows in code and organization size. Let me walk you through a number of challenges and good decisions for scalable applications.

In this talk we'll dive into the approaches and strategies needed to create a great unit test environment for your JavaScript and React applications. We'll examine what makes the perfect test, what to avoid, and how to use more complex features like mocks and spies to enable you to write tests more easily.

Let's talk about how React fares in the real world when 'the business' gets involved.

If React is designed for the view layer, and we’re using Redux or something similar for the state, then where does the business logic go? This talk looks at the different options and tries to answer that question.

In this talk, you'll learn how to pitch a design system to your boss, rarely discussed technical caveats and challenges, and how to set your design system up for success from the start.

Let's walk this road thogheter and I promise it will all be fine and you will leave with an ideia of type of styling is better for each project. Hint: There is no perfect way...

In this talk, we'll do a deep dive into how React Native and Metro goes about resolving platform specific code, common patterns for separating platform-specific code, and look at those same patterns from the perspective of a platform developer to see how we can make them more resilient to new & upcoming platforms.

Suspense is an exciting new fundamental arriving soon in React. This talk explores this interesting new paradigm in-depth on the client and on the server, outlining its implications for current and future front-end development.

People in our community are bursting with excitement about ReasonML - but why is that, and what does it have to do with our beloved React? Is this something for hipster types only, or will we all be using it in a year's time?

Since Apple and Google have introduced ARKit and ARCore respectively, the excitement for easy access to Augmented Reality (AR) on everyday mobile devices is exploding. So let’s take a look of how we can marry this new medium with React Native in the most efficient way. We head dive into AR by understanding our UX goals with an interactive AR stage demo (so bring your device!), identify implementation paths as well as existing and new libraries.

Today's front-end community is highly fragmented when it comes to styling. From good-old css, css modules, and inline styles to numerous css-in-js libraries—there is a range of options to choose from. This talk puts forth some best practices discovered while building a React component library shared across all different engineering teams at Signavio.
