Cristiano Rastelli gave a presentation about design systems and component-based design. He discussed Atomic Design, React, Cosmos, and examples from Badoo's design system. He emphasized that design systems provide consistency, efficiency, and collaboration benefits. Complex systems work best when evolved from simple, working systems rather than designed entirely from scratch.

Things to notice React • we generally have only pure components (this is a UI library) • we split components is sub-components (our files are generally quite small, and if they’re not then is a “code smell” for us) • we use prop-types for type checking (and documentation) CSS • we use BEM notation for the classnames • classnames are “name-spaced” to avoid conflicts • extensive use of design tokens as Sass variables (when appropriate)

A complex system designed from scratch never works and cannot be patched up to make it work. You have to start over with a working simple system. ” complex system evolved from a simple system from scratch never works working simple system cannot be patched up
