Schema visibility control in GraphQL - Cheat Sheet & Quick Revision

Recall & Review

beginner

What is schema visibility control in GraphQL?

Schema visibility control is the practice of limiting which parts of a GraphQL schema are visible or accessible to different users or clients, helping protect sensitive data and simplify the API.

How can you restrict access to certain fields in a GraphQL schema?

You can restrict access by using authorization logic in resolvers or by creating separate schema layers that expose only allowed fields to specific users.

intermediate

What is a common method to implement schema visibility control?

A common method is to use schema stitching or schema delegation to create different schema views for different user roles, showing only permitted fields.

beginner

Why is schema visibility control important in GraphQL APIs?

It helps protect sensitive information, reduces data exposure risks, and improves API usability by showing only relevant data to each user.

intermediate

Can schema visibility control affect API performance?

Yes, by limiting visible fields, it can reduce data processing and network load, improving performance for clients.

What does schema visibility control primarily help with in GraphQL?

A Limiting data exposure to users

B Increasing query complexity

C Adding more fields to the schema

D Improving database indexing

Schema visibility control limits which parts of the schema users can see, protecting sensitive data.

Which technique can be used to create different schema views for different users?

A Indexing

B Database sharding

C Schema stitching

D Caching

Schema stitching allows combining or splitting schemas to control visibility for different users.

Where is authorization logic usually applied to control schema visibility?

A In the network layer

B In the database schema

C In the client UI

D In resolvers

Resolvers handle data fetching and can include checks to restrict access to fields.

What is a benefit of hiding fields users don’t need in a GraphQL schema?

A Simplifies the API for users

B Increases server load

C Makes queries slower

D Exposes more data

Showing only relevant fields makes the API easier to understand and use.

Does schema visibility control replace the need for authentication?

A Yes, it replaces authentication

B No, it complements authentication

C Only for public APIs

D Only for internal APIs

Schema visibility control works together with authentication to secure data access.

Explain how schema visibility control helps protect sensitive data in a GraphQL API.

Think about who can see what data and how to control it.

Describe methods to implement schema visibility control in GraphQL.

Consider both code and schema design approaches.
