Express handler receiving HTTP response reference

[asieraduriz]

Hello! I just started with my pet project using express and this library to serve my graphql endpoint, and I hit a snag when developing some authentication methods.

It is my understanding that in order to log out, the server should be the one setting the cookies to expire to abstract it from the Frontend, but I wasn't capable of finding that snippet of code in your documentation.

I sort of pieced together what might be helpful and this is what I came up with

import express from "express";
import { schema } from "./schema";
import { createHandler } from "graphql-http/lib/use/express";
const app = express();

app.use("/graphql", (req, res, next) =>
  createHandler({
    schema,
    context: (req) => ({ req, res }),
  })(req, res, next)
);

// Start the server
const PORT = 4000;
app.listen(PORT, () => {
  console.log(`Server is running at http://localhost:${PORT}/graphql`);
});

I would very much appreciate any validation if there's any issue applying such code.
My intention is that for the logout mutation, the resolver can influence the response by setting some headers.

Thank you
