Learn how to build scalable, fully type-safe APIs in your Next.js projects using tRPC.

tRPC + Next.js

tRPC is a framework for building type-safe APIs without schema duplication. It uses TypeScript inference to make backend and frontend share the same types.

🚀 Features

  • No REST, no GraphQL
  • Fully type-safe, end-to-end
  • Great developer experience

âš¡ Example

const appRouter = createRouter()
  .query("hello", {
    resolve() {
      return "world";
    }
  });

Use it with Next.js API routes or App Router server actions.
