Exploring the integration of authentication and authorization in GraphQL, the article distinguishes between authentication, which verifies user identity, and authorization, which determines user permissions within a system. It outlines that while GraphQL creators suggest placing authorization in the business logic layer, authentication logic should be executed for all requests, ideally in the middleware part of the system. The article demonstrates this process using the Express framework and Apollo Server, highlighting how authentication can be handled independently of GraphQL by leveraging existing REST skills. On the client side, token-based authentication is discussed along with strategies for token storage, retrieval, and inclusion in requests, using Apollo Client as an example. The importance of understanding that authorization is business-specific logic is emphasized, suggesting it should be centralized in the codebase to avoid redundancy. Monitoring and securing GraphQL APIs with platforms like Moesif is also recommended, emphasizing the reuse of HTTP API authentication skills across both REST and GraphQL frameworks.
