Getting user IP in trpc without req object?

I used to get the users IP like so, just giving the package the req object:

const requestIp = require('request-ip');
const ip = requestIp.getClientIp(req);

const requestIp = require('request-ip');
const ip = requestIp.getClientIp(req);

With trpc, I don't have access to Next.JS's req object - how would I solve this now?

You have access On the createaContext function you have next request

thanks for the reply I'm not sure how exactly I would add it though Some help or a hint would help me out a lot! My context.ts file looks like this:

// src/server/router/context.ts
import * as trpc from "@trpc/server";
import * as trpcNext from "@trpc/server/adapters/next";
import { prisma } from "../db/client";

/**
 * Replace this with an object if you want to pass things to createContextInner
 */
type CreateContextOptions = Record<string, never>;

/** Use this helper for:
 * - testing, where we dont have to Mock Next.js' req/res
 * - trpc's `createSSGHelpers` where we don't have req/res
 **/
export const createContextInner = async (opts: CreateContextOptions) => {
  return {
    prisma,
  };
};

/**
 * This is the actual context you'll use in your router
 * @link https://trpc.io/docs/context
 **/
export const createContext = async (
  opts: trpcNext.CreateNextContextOptions
) => {
  return await createContextInner({});
};

type Context = trpc.inferAsyncReturnType<typeof createContext>;

export const createRouter = () => trpc.router<Context>();

// src/server/router/context.ts
import * as trpc from "@trpc/server";
import * as trpcNext from "@trpc/server/adapters/next";
import { prisma } from "../db/client";

/**
 * Replace this with an object if you want to pass things to createContextInner
 */
type CreateContextOptions = Record<string, never>;

/** Use this helper for:
 * - testing, where we dont have to Mock Next.js' req/res
 * - trpc's `createSSGHelpers` where we don't have req/res
 **/
export const createContextInner = async (opts: CreateContextOptions) => {
  return {
    prisma,
  };
};

/**
 * This is the actual context you'll use in your router
 * @link https://trpc.io/docs/context
 **/
export const createContext = async (
  opts: trpcNext.CreateNextContextOptions
) => {
  return await createContextInner({});
};

type Context = trpc.inferAsyncReturnType<typeof createContext>;

export const createRouter = () => trpc.router<Context>();

On the createContext function On the opts parameters you have both next request and response
