Set response header in resolver

Question

I am trying to implement authentication in a custom resolver function but to achieve that, I must be able to set a cookie on the response.

I found the following docs on what data is available, unfortunately, I see no way to access the response object nor the response headers. How would this be achievable?

Answer 1

I recommend you to keep the HTTP layer separate from the GraphQL layer. That means:

• don't deal with cookies in resolvers
• don't expect certain resolvers in HTTP middleware

In my experience, authentication work best when handled exclusively on the HTTP layer - use standard Laravel mechanisms such as guards, described in https://laravel.com/docs/authentication and tie it into your Lighthouse server through middleware such as Nuwave\Lighthouse\Http\Middleware\AttemptAuthentication.

Answer 2

If you want to set something in the response of the graphQL you can use EndRequestEvent.
