Middleware in oRPC

Middleware is a powerful feature in oRPC that enables reusable and extensible procedures.

Overview

const authMiddleware = os
  .$context<{ something?: string }>() // define dependent-context
  .middleware(async ({ context, next }) => {
    // before
    const result = await next({
      context: { user: { id: 1, name: 'John' } }
    })
    // after
    return result
  })
