Why server setup enables GraphQL - Quick Recap

Recall & Review

beginner

What role does the server play in enabling GraphQL?

The server processes GraphQL queries, fetches data from databases or other sources, and returns exactly the requested data to the client.

intermediate

Why is server setup important for GraphQL's flexibility?

The server defines the GraphQL schema and resolvers, which control how clients can query data and how the server responds, enabling flexible and efficient data fetching.

beginner

How does the server ensure clients get only the data they ask for in GraphQL?

The server interprets the client's query and runs resolvers that return only the requested fields, avoiding over-fetching or under-fetching data.

intermediate

What is a GraphQL resolver and where is it set up?

A resolver is a function on the server that fetches or computes the data for a specific field in the GraphQL schema. It is set up during server configuration.

How does server setup affect the security of a GraphQL API?

The server setup controls authentication, authorization, and validation of queries, protecting data and ensuring only allowed data is accessible.

What does the GraphQL server primarily do?

A Creates user interfaces

B Processes queries and returns requested data

C Runs client-side code

D Stores data permanently

The server processes GraphQL queries and returns exactly the data requested by the client.

Where are GraphQL resolvers defined?

A On the client application

B In the database

C In the server setup

D In the browser

Resolvers are functions defined on the server to fetch or compute data for each field.

Why does GraphQL server setup improve data fetching?

A It fetches only requested data

B It fetches all data regardless of query

C It ignores client queries

D It duplicates data

The server returns only the data fields requested by the client, avoiding extra data transfer.

How does server setup help secure a GraphQL API?

A By controlling authentication and authorization

B By allowing all queries without checks

C By hiding the schema from clients

D By storing passwords in plain text

The server setup manages who can access what data through authentication and authorization.

What is defined in the GraphQL server schema?

A The network protocol

B The client user interface layout

C The database engine type

D The structure of data clients can query

The schema defines the types and fields clients can request in queries.
