Open Source GraphQL engines do not perform compile-time optimizations on queries. We have built a compiler for GraphQL that turns a query into JS which with 6x the performance of the runtime implementation. About Rui (https://twitter.com/raraujoc) Rui is beard fluid software engineer that enjoys making code dance mainly with Latin rhythms. Previously very focused on mobile and frontend, he has been going down the stack slowly but surely. ## Advanced Styled Components Toolkit As the world scrambles to cope with CSS in a post-Webpack world many of us have moved to some form of CSS-in-JS to pair styles with our components. Styled-Components 💅 offers a flexible mix of classic CSS syntax and functional JS power. In this talk will review the basics of Styled Components and explore some of the lesser-known features of the library, intended and otherwise. About Mims (https://twitter.com/mimshwright) Mims is a freelance software developer and product manager who can't seem to help himself from obsessing over CSS. ## Lightning talks Have you discovered a new project, fall in love with a technique, or avoided a pitfall.
