GraphQL Middlewares

Casbin follows the officially suggested way to provide authorization for GraphQL endpoints by having a single source of truth for authorization: https://graphql.org/learn/authorization/ . In another word, Casbin should be placed between GraphQL layer and your business logic.

// Casbin authorization logic lives inside postRepository
var postRepository = require('postRepository');
 
var postType = new GraphQLObjectType({
  name: ‘Post’,
  fields: {
    body: {
      type: GraphQLString,
      resolve: (post, args, context, { rootValue }) => {
        return postRepository.getBody(context.user, post);
      }
    }
  }
});
