How can I set a Cookie from the server (for the login)?

This code is not working..

import { initTRPC } from "@trpc/server";
import { createHTTPServer } from "@trpc/server/adapters/standalone";
import cors from "cors";
import { z } from "zod";
const t = initTRPC.create();

const publicProcedure = t.procedure;
const router = t.router;

const appRouter = router({
  login: publicProcedure
    .input(
      z.object({
        login: z.string(),
        password: z.string(),
      })
    )
    .mutation(async (opts) => {
      opts.ctx.res.cookie("cokkieName", 7777, {
        maxAge: 900000,
        httpOnly: true,
      });
    }),
});

export type AppRouter = typeof appRouter;

// create server
createHTTPServer({
  middleware: cors(),
  router: appRouter,
  createContext({ req, res }) {
    return { req, res };
  },
}).listen(2022);

Your t needs to be passed the typedef of your context

As shown here https://trpc.io/docs/server/adapters/express

Express Adapter | tRPC

Example app

// created for each request
const createContext = ({
  req,
  res,
}: trpcExpress.CreateExpressContextOptions) => ({}); // no context
type Context = Awaited<ReturnType<typeof createContext>>;
const t = initTRPC.context<Context>().create();
