cookies not being set in procedure

This is all the code for setting my cookie

import { publicProcedure, router, userProcedure } from '$lib/trpc/t'

export const user = router({
  testCookie: publicProcedure
    .query(async ({ ctx: { cookies } }) => {
      cookies.set("name", "value", {
        path: '/'
      })
    })
})

import { publicProcedure, router, userProcedure } from '$lib/trpc/t'

export const user = router({
  testCookie: publicProcedure
    .query(async ({ ctx: { cookies } }) => {
      cookies.set("name", "value", {
        path: '/'
      })
    })
})

I'm using svelte-kit, but this doesn't set the cookie

you probably need to set it on the response object

@alex / KATT yeah, how do I get access to that in the context?

Alex / KATT 🐱•15mo ago

you can pass it in your createContext-fn

export async function createContext(
  opts: trpcNext.CreateNextContextOptions,
) {
  return { req: opts.req, res: opts.res }
}

export async function createContext(
  opts: trpcNext.CreateNextContextOptions,
) {
  return { req: opts.req, res: opts.res }
}

@alex / KATT I don’t have access to opts, can this be because I’m using trpc/sveltekit? This is how my createContext looks like

import type { RequestEvent } from '@sveltejs/kit';
import type { inferAsyncReturnType } from '@trpc/server';
import { prisma } from '$lib/prisma';

export async function createContext(event: RequestEvent) {
  let cookies = event?.cookies
  return {
    cookies,
    prisma
  };
}

export type Context = inferAsyncReturnType<typeof createContext>;

import type { RequestEvent } from '@sveltejs/kit';
import type { inferAsyncReturnType } from '@trpc/server';
import { prisma } from '$lib/prisma';

export async function createContext(event: RequestEvent) {
  let cookies = event?.cookies
  return {
    cookies,
    prisma
  };
}

export type Context = inferAsyncReturnType<typeof createContext>;
