Yarr is yet another React router library, but with a focus on enabling the render-as-you-fetch concurrent UI pattern by offering both component code preloading and data preloading. This behavior is enabled even without opt-in to React's experimental Concurrent Mode. Yarr was originally developed for use with Relay (formally Relay Modern) in September 2020 for internal use at Contra.
More info coming soon.
Yarn requires React >=16.14.0.
npm install yarr
# or
yarn add yarr
