By default request and response passed as third argument in every query and mutation

resolvers = {
    Query: {
        hello: (parent, { name },rootValue,context) => {
            console.log(rootValue)
            return `hello ${name || "world"}`
        },
    },

I don't follow what you mean but req and res is available in the context which is third parameter of the resolver function.

(root, args, context, info)

context -> req, res and the rest.

If you have any issues, please create a new issue by following this template here;
