Authentication and Authorization (1/1)
How to implement authentication and authorisation in GraphQL?
GraphQL execution should begin after authentication middleware confirms the user’s identity and passes that information to the GraphQL layer. But after that, you still need to determine if the authenticated user is allowed to view the data provided by the specific fields that were included in the request.
It’s simple to use any Express middleware in conjunction with graphql-http. In a REST API, authentication is often handled with a header, that contains an auth token which proves what user is making this request. Express middleware processes these headers and puts authentication data on the Express request object. Some middleware modules that handle authentication like this are Passport, express-jwt, and express-session. Each of these modules works with graphql-http.
