## The tech behind a design system that scales
by Monica Lent

Most teams who end up implementing a design system do so because they need a more efficient way to propagate design ideas and their implementations across various products and codebases. They want to stop reinventing the wheel and offer a consistent experience to their end-users — but they also want to be able to adapt and adjust without a ton of manual overhead. In this talk, you'll see how SumUp uses React, Emotion, and Storybook to implement a design system that scales: in terms of people, products, and processes.

## Embracing the render method – an unconventional approach to data fetching
by Daniel Berndt

Attempting to fit CSS into React's component model has led to a great deal of innovation – bringing a component's style definition closer and closer to its render method.
Daniel will present a similar process for data fetching. In a component-centric code base, GraphQL is a big improvement compared to traditional REST Apis. It allows defining a query for each component to describe the exact shape of data it needs. But the query and the render method can get out of sync. This talk will explore whether it is possible to infer the shape of the data from within the render method, and will discuss its implications.

About Daniel (

Daniel has been a web developer for 7 years. He has a background in Computer Linguistics but found it more useful to put websites in front of people. His current project is – a card-based and playful tool for project management using React and an unconventional approach for data fetching.
