What are some effective techniques for authorization in GraphQL?

There are several techniques for implementing authorization in GraphQL, including role-based access control, field-level authorization, and using middleware for authentication checks.

Can you explain role-based access control in more detail?

Sure! Role-based access control (RBAC) assigns permissions to users based on their roles. In GraphQL, you can define roles and restrict access to certain queries or mutations based on the user's role.

What about field-level authorization?

Field-level authorization allows you to control access to specific fields in your GraphQL schema. This means you can restrict access to sensitive data based on user roles or permissions.

How can I implement middleware for authorization?

You can implement middleware in your GraphQL server to check user permissions before resolving a query or mutation. This can be done using libraries like Apollo Server or Express.
