Accessing req & res in Trpc + Next.js

Total beginner question. Would love to move my next.js project over to trpc, but am having problems getting started. How would I access req & res objects in NextJS with trpc? My current code / function starts like this:

export default async function createPaymentIntent(req, res) {
    const { product, email, name, coupon } = req.body;
//...
}

export default async function createPaymentIntent(req, res) {
    const { product, email, name, coupon } = req.body;
//...
}

Now, I'm trying to do the same thing, but with trpc:

export const paymentRouter = createRouter().query(
  "stripe.create_payment_intent",
  {
    input: z
      .object({
        text: z.string().nullish(),
      })
      .nullish(),
    resolve({ ctx }) {
      console.log(ctx.req); ??

      return {
        greeting: `Creating Intent`,
      };
    },
  }
);

export const paymentRouter = createRouter().query(
  "stripe.create_payment_intent",
  {
    input: z
      .object({
        text: z.string().nullish(),
      })
      .nullish(),
    resolve({ ctx }) {
      console.log(ctx.req); ??

      return {
        greeting: `Creating Intent`,
      };
    },
  }
);

you get data from input and return data in the return statement if you need req or res for something else, you can go into the function where context is created and pass them there but i'd recommend to try without first

resolve: ({ ctx, input }) => { 
  return `hello, ${input.text}`;
}

resolve: ({ ctx, input }) => { 
  return `hello, ${input.text}`;
}

yeah, tRPC is a different paradigm from REST, if you think you need req/res you're probably doing something wrong

Oh damn, I didn't know that it's totally different in this regard

you might need it occasionally if you're doing some weird stuff with headers or something have you read the docs at all?
