[Http headers] I need to send a cookie.

How can I access to the response headers since this lib provides only the req parameter but not res ?

You’re right, they’re not defined in the example I gave above, so it wouldn’t work. What you actually have to write is something like this (which wraps the graphqlHTTP middleware in a function that acts as middleware:

app.use('/graphql', (req, res) => {
  return graphqlHTTP({
    schema,
    graphiql: true, // or whatever you want
    context: { req, res },
  })(req, res);
);

I’m not sure why you thought you had to fork the project to do this… the following should work:

app.use('/graphql', graphqlHTTP({
  schema,
  graphiql: true, // or whatever you want
  context: { req, res },
});

and in your resolve function:

resolve: (root, args, context) => {
  let cookieValue;
 /* your code here */
  context.res.set('cookie', cookieValue);
}
