Securing GraphQL – authentication and authorization

Securing a GraphQL API, particularly in a NestJS environment, requires a nuanced approach compared to traditional REST APIs. While the fundamental principles of authentication and authorization remain the same, the implementation details can differ due to the nature of GraphQL’s single endpoint and complex query structures. Let’s delve into the intricacies of securing a GraphQL API, highlighting the differences from REST APIs and exploring mechanisms to handle authentication and authorization effectively.

Understanding the differences

We’re now familiar with the authentication and authorization mechanisms that are available for REST APIs. However, building secure GraphQL APIs can be a little bit different. Here are some of the key differences you need to keep an eye on:

• Single endpoint challenge: Unlike REST APIs, which typically have multiple endpoints corresponding to different resources...
