NextJS Starter Project, converted to use Typescript, Rebass, @Emotion, and Styled-System
Check the src/theme.ts file for all the colors and variants being used.
All of the styles in <style jsx> tags were converted to variants.
The global style was added to _app.tsx using Global/css from @emotion.
Also added a webpack resolution / tsconfig path for the src folder, so all imports will be relative to that folder.
