Zero-API, React, & TypeScript

⚡️ Probably the fastest way to build a React Native app with your own backend ⚡️


A monorepo containing:

  • Next.js web app
  • React Native app with Expo
  • A tRPC-API which is inferred straight into the above.
  • Prisma as a typesafe ORM

In tRPC you simply write API-functions that are automatically inferred straight into your frontend - no matter if it's React, React Native, or something else (that is TS/JS-based).
